ONAP Developer Set-Up

Follow the steps below to set up the development environment on your client machine, and to establish credentials with which you may access the repositories.

Create a Linux Foundation Account

Follow the instructions on the identity portal to create a Linux Foundation account and get access to the ONAP Gerrit instance.

Verify that you can log in at https://gerrit.onap.org/ and that you can see the ONAP list of repositories.

Basic Setup


Install git for your OS in accordance with https://www.atlassian.com/git/tutorials/install-git

Since this is common for all OS, we will also use it to generate our SSH keys as well :


This should generate a private and public ssh key.

The public ssh key can then be uploaded to Gerrit (user setting, ssh keys, add new key) or elsewhere as needed for authorization.


ONAP is moving to Java 11 but many projects still use Java 8.

Download and install the appropriate openjdk version in accordance with the component you are working and set JAVA_HOME environment variable to point to that


Download the latest Maven using installer from https://maven.apache.org/download.cgi

Add maven to your path variable.

To test the new installation run:

mvn -version

Use the settings.xml found in the oparent repo

Save this Maven settings.xml as your ~/.m2/settings.xml (windows c:\users\<username>\.m2)

WSL users can point to one common repo across Windows and Ubuntu as :

ln -s /mnt/c/Users/<username>/.m2 ~

Proxy settings for Maven (if required)

If you are behind a proxy you can add a proxy section to your settings.xml 

Proxy Settings

OS Specific Instructions

MAC/OSX  (in review under 10.15.7)

get your MBP 2020 16 inch ready for development - refer to http://wiki.obrienlabs.cloud/display/DEV/Developer+Guide#DeveloperGuide-OSX

Install homebrew package manager - 

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

python should already be installed. - do a --version check

install openstack tools

install docker (dmg) - https://docs.docker.com/docker-for-mac/install/#download-docker-for-mac

Redhat/CentOS (in review under RHEL 8.3)

Add the following option to your MAVEN_OPTS in order not to periodically hang on downloading artifacts in linux


enable IP4 forwarding to enable the RHEL VM to act as an edge router - without this docker containers cannot communicate

add to /etc/sysctl.conf
net.ipv4.ip_forward = 1

Install docker (required for some repos like dcae-inventory off dcae
to install kubernetes follow Cloud Native Deployment#Scriptedundercloud(Helm/Kubernetes/Docker)andONAPinstall-SingleVM

Ubuntu (in review under 20.04 )

enable ubuntu desktop

apt-get update

apt-get install ubuntu-desktop

enable static IP

vi /etc/network/interfaces


iface enp0s25 inet static







disable strict host checking (client and server)
in ~/.ssh/config
Host *
   StrictHostKeyChecking no

Enable non CD repositories so an apt-get update will work

comment out the CD first line in /etc/apt/sources.list
enable ssh if skipped during installation so we can remote sshsudo apt-get install openssh-server
enable root login and gui (no sudo su -)
sudo passwd root

sudo usermod -U root

sudo reboot now

sudo vi /etc/lightdm/lightdm.conf





: enable root login

vi /etc/ssh/sshd_config
PermitRootLogin prohibit-password
PermitRootLogin yes

systemctl restart sshd

Add the following option to your MAVEN_OPTS in order not to periodically hang on downloading artifacts in linux

in /etc/environment


Install docker (required when building docker images)

use the current as of 20180621 17.03 version in the script
which is

curl https://releases.rancher.com/install-docker/17.03.sh | sh

Connecting to ONAP Gerrit

SSH Connection (Recommended)

Log in to the Gerrit host https://gerrit.onap.org/, pull down the menu under your user name (at the extreme top right of the browser window), click on "Settings":

Click your account name on the top right corner of the website and click on Settings.

Add the public ssh key that you created in the previous step.

HTTPS Connection

If you choose to use HTTP/HTTPS, you'll need to generate an access password. Log in to the Gerrit host https://gerrit.onap.org/, pull down the menu under your user name (at the extreme top right of the browser window), click on "Settings", and select "HTTP Password"

This password may have a limited time to live, so you might get errors like this one:

Problem running 'git remote update gerrit'
Fetching gerrit
fatal: unable to access 'https://USERNAME@gerrit.onap.org/r/a/mso/ ': Unknown SSL protocol error in connection to gerrit.onap.org:443 error: Could not fetch gerrit

Regenerating a password will most likely solve the connectivity issue. Sometimes, the Gerrit interface on HTTPS might be temporarily faulty, so retries might be needed.

Proxy setting for IntelliJ and Git (if required)

For developers working with a proxy, you might have proxy issues connecting to Linux Foundation website. To avoid the connection issue, you must define the proxy setting for both IntelliJ and Git.

To configure the proxy settings in IntelliJ;

click File -> Settings -> Appearance & Behavior -> System Settings -> HTTP Proxy

 enter the correct proxy settings and click Apply.

In case of Manual proxy configuration, while entering the Host name, there is no need to write http:// in front of the URL. For example, if the proxy value is http://one.proxy.com, you would put one.proxy.com as the Host name

To configure the proxy settings for Git, play the following command:

git config --global https.proxy https://<proxy username>:<proxy password>@<proxy url> 
git config --global http.proxy http://<proxy username>:<proxy password>@<proxy url>

Note: while entering the proxy username, sometimes it may require to add the domain name in front.



Install Eclipse

Download and run the installer from: Install Eclipse. Select "Eclipse IDE for Java Developers" to install.

ONAP Eclipse Java Formatter 

Download onap-java-formatter.xml and import into Eclipse. 

(updates to the settings should be committed and merged back into the repository)

ONAP uses Google Java Style with some modifications. ( See Java code style )

Using the Eclipse Formatter file above and maven plugin configuration in pom.xml as per pom.xml 

(https://code.revelc.net/formatter-maven-plugin/ for Eclipse formatter and https://github.com/diffplug/spotless/tree/master/plugin-maven for import order)

Example pom.xml configuration
                Using https://code.revelc.net/formatter-maven-plugin/ for Eclipse formatter
                Using https://github.com/diffplug/spotless/tree/master/plugin-maven for import order
                Use in combination to rewrite code and imports, then checkstyle
                mvn formatter:format spotless:apply process-sources
                     <!-- https://code.revelc.net/formatter-maven-plugin/
                          use mvn formatter:format to rewrite source files
                          use mvn formatter:validate to validate source files -->
                <!-- https://github.com/diffplug/spotless/tree/master/plugin-maven
                     use mvn spotless:apply to rewrite source files
                     use mvn spotless:check to validate source files -->

The combination can be used in a maven command to rewrite code and imports, then checkstyle audit like so

Example maven command
mvn formatter:format spotless:apply process-sources

Install useful plugins for Eclipse

Setting up the ONAP Checkstyle for Eclipse

Set "ONAP" configuration in Eclipse

To set the newly built checkstyle files in Eclipse:

  1. Preferences->Checkstyle
  2. Click "New"
  3. Select "External Configuration File"
  4. Give it a name eg ONAP
  5. Point at the file <your_git_folder>/oparent/checkstyle/src/main/resources/onap-checkstyle/onap-java-style.xml

  6. Click OK
  7. Select "ONAP" configuration and click "Set as Default"
  8. Select "Apply and Close"

Apply "ONAP" configuration to a project in Eclipse

Now we need to activate the checkstyle on one project and set it as the blueprint for all of them:

  1. Select a project in eclipse and right click->Properties→Checkstyle
  2. check "Checkstyle active for this project"
  3. Select the "ONAP" checkstyle profile
  4. Click "Apply and Close"

Spread blueprint to other projects for Eclipse

Now spread the profile to all other projects:

  1. Select all the projects you want to apply the profile to in the Eclipse project explorer (not the one that you set up above)

Set up SonarLint towards ONAP for IntelliJ


  • You need to be part of the onap organization in GitHub (see GitHub, click on your icon and select 'My Organizations')
    If you are not a member of this organization email support.linuxfoundation.org  and ask to be added to the onap organization in GitHub
    Note. It is possible to enter a different organization if you at least member of 1 organization (you can create your own in GitHub).
    The plugin wizard crashes if you are member of no organization at all, see this Bug: https://jira.sonarsource.com/browse/SLI-426
  • Make sure you have added the SonarLint plugin

To use SonarLint with Onap projects you need to setup a connection with SonarCloud

  1. Select, File, Settings, Tools, SonarLint.
  2. Click on + beside the 'SonarCube / SonarClod connections' box to add a new connection
  3. Set Configuration Name to something like 'ONAP'

  10. Click [Finish] to close the wizard
  11. Click [OK] to leave settings

Then you need to bind each project to the corresponding project in GitHub/SonarCloud:

  1. Select, File, Settings, Tools, SonarLint, Project Settings
  2. Enable (check) 'Bind project to SonarQube / SonarCloud'
  3. Select the connection created above using the [Configure the connection] button
  4. Enter the project name (e.g. 'onap_ccsdk-sli-plugins') or select it using [Search in list..] 
  5. Start typing the name of your project, and it should appear in a list box where it should be selected.
  6. Click [OK] to finish

Optional Tools & Utilities


Check which version of python your project is using before installing. 

Download Python from https://www.python.org/downloads/

Add python binary to Path.

Install "pip3", if you plan to use git-review.

sudo apt-get update
sudo apt-get -y install python3-pip
pip3 --version

git-review (optional)

In a shell, type the following command (assumes you installed python above) :  

pip3 install git-review

To use git review, you have to be in a Git clone directory that already contains a (possibly hidden) .gitreview configuration file (see Gerrit/Advanced usage#Setting up a repository for git-remote)

The Git and git-review installation steps above are derived from the description at: https://www.mediawiki.org/wiki/Gerrit/git-review#Windows 

Configure Git to remember your Linux Foundation user name and email address (the user name and email address associated with your Linux Foundation login):

git config --global user.email <your_LF_account_email>

git config --global --add gitreview.username <your_LF_user_name>

Configure git review

git config --global gitreview.remote origin

If you are using VPN, you might encounter a proxy problem while connecting to the Linux Foundation website. To avoid the problem, you should add the proxy setting in git config, using the following command:

git config --global https.proxy https://<proxy username>:<proxy password>@<proxy url> 

git config --global http.proxy http://<proxy username>:<proxy password>@<proxy url>

NOTE: When entering the proxy username, you might be required to add the domain name in front of the username.


The dcae build will install npm in most cases.

However you can install it yourself from https://nodejs.org/en/download/

Verify your installation by 

npm -v

Local SonarQube Setup

It can be useful to have SonarQube running locally rather than pushing through CI for feedback.

This can be done using docker:

Images of the Community, Developer, and Enterprise Editions are available on Docker Hub.

  1. Start the server by running:

    $ docker run -d --name sonarqube -p 9000:9000 sonarqube:latest
  2. Log in to http://localhost:9000 with System Administrator credentials (login=admin, password=admin).
  3. Click the Create new project button to analyze your first project.

Other Optional Tools

The component you are working on may require additional tool installations, see the relevant section under Development Guides.

Troubleshooting & Know Issues

Windows Limitations

Some repos might not clone in Windows until some file paths are reduced below 255 chars.

Enable long paths in windows as

git config --system core.longpaths true

Hack oparent to fix "curly bracket" issue

The first issue is that the current ONAP master tagged version of the checkstyle does not work with Eclipse Oxygen/Photon (and maybe other versions) because of the "curly bracket" issue. There is a fix on the way but it's not here yet. The current tagged version of oparent we are using in Policy is 1.2.1.

To get around this issue, check out oparent, checked out the 1.2.1 tag, fixed the "curly bracket" bug and built it on my local machine.

  1. Check out oparent
  2. git tag -l
  3. git co tags/1.2.3 -b 1.2.3
  4. If you want CheckStyle to ignore generated files, do the following:
    1. Add the following tag to the above file:
      <module name="SuppressionFilter">
        <property name="file" value="<absolute path to the directory of the file>/suppressions.xml"/>
    2. Create a file called "suppressions.xml" in the folder given above, and put the following content in it:
      <?xml version="1.0"?>
      <!DOCTYPE suppressions PUBLIC
        "-//Checkstyle//DTD SuppressionFilter Configuration 1.2//EN"
        <suppress files="[\\/]generated-sources[\\/]" checks="[a-zA-Z0-9]*"/>
  5. The versions in the POMs in oparent are snapshot, so we need to change those to 1.2.1
     mvn versions:set -DnewVersion=1.2.1
  6. Now build locally:
    mvn clean install


  • No labels


  1. If you have Git installed, you can use the "ssh-keygen" command from the Git Bash shell to generate a private-public key pair.  (This is not as sophisticated as the Putty/plink configuration, but much easier to make it work.)  Then look in your home directory for the .ssh/id_rsa.pub file and upload its contents to the Gerrit web site's SSH area.  At that point you are set to type git commands in Git Bash.


  2. Chris: good idea! If you've got editing permissions, go ahead and modify the page acccordingly.

  3. https://nexus.onap.org/content/repositories/public/   is also need for org.eclipse.core.runtime and sth else

  4. Is there any guide for remote debug with IDEs ? thx

    1. Xing, 

          Hi, good question and definitely required, I was planning on posting a section to the devops wiki on this later today.  It involves exposing a different port for each docker container that has a JRE after an agreed on port like 5005 is enabled and the JVM restarted.

          Ideally the compose files would enable the debug port in prep of this during deployment - I'll enter a JIRA on this as well.

      UCA-25 - Getting issue details... STATUS


  5. In the web page above instructions for windows users there is mention of a known_hosts file. I was expecting to see a lists of known_hosts to be added somewhere here in the instructions. 


    Copy/paste the known_hosts entries listed, into a file named known_hosts under your .ssh profile (something like C:\Users\<my-id>\.ssh) (if known_hosts does not exist, create it).

    Install NodeJS" 

    1. Steven,

         The mention of known_hosts can be ignored in my experience.  The dynamic file will get created on your first ssh and fill up on every new connect with the server/key pair.  Actually without a "-o StrictHostKeyChecking=no" in your ssh the known_hosts creates issues when you rebuild environments and swap out an IP for a local DNS name like robot - in that case you can also just remove that entry.


  6. I disagree with the advice (in the Installing Git section) to checkout files with Windows-style line endings (on Windows). I am aware of some unit tests in ONAP that compare test-generated outputs with fixed expected outputs, stored as file resources within the git repo. Some of these unit tests directly compare the raw file contents and expect an exact match. Automatic CRLF conversion will cause test failures for such projects.

    1. Have experienced this in the AAI tests. The Java code could/should be changed to use the portable System.lineSeparator() method instead of literal "\n" and "\r\n" embedded strings.

    2. I think we should use this configuration.

      git config --global core.autocrlf input
  7. Please add a pointer to the appropriate page that explains ONAP has adopted the Google no-tabs-just-spaces code style. 

    1. Here is the page that Chris refers to: Java code style

      1. However, following that code style is not mandatory for R1 Amsterdam. Expect it to be mandatory in a future release.

  8. Does anybody recently proceeded successfully with clone of project on Windows e.g. 7?

    1. I find running VMware workstation on Windows and VMware Fusion on OSX works well - then you just develop in Ubuntu 16 or Redhat 7.3 in a VM.

      When I was at Nokia we developed this way on our windows machines so we could be in sync with our Linux developer box - in a config way

      That being said, I have ran into projects that came from a windows environment in ONAP (the CR/LF) so some developers here do run natively.  I have cloned on a windows 10 machine but this is inside cygwin - will post details

  9. Hi All,

    I was trying to build onap code and found some errors. can you please suggest is there any work around.

    I am using git bash and OS is windows 10.

    First time execution of command "repo init -u https://github.com/dbainbri-ciena/onap-manifest" found bellow error.

    ImportError: No module named fcntl

    i downloaded  fcntl.py and paste it into python package library path.

    after execution of same command there are some more errors for that i need help to resolve.please find bellow error:

  10. How do you download the ONAP JAR package? URL......

  11. Hi?

    in Unix Setup >  Ubuntu 16.04,   it explains steps on Ubuntu 16.04.  My question is that we can use Ubuntu1 16.04  version now ?  Because in Deploying SDC on a Linux VM for Development ,  it highlights ubuntu 14.04 (do not use ubuntu 16.04).

    which one is the latest tip?

  12. Hi!

    I'm trying to push a commit towards gerrit.onap.org with the git review command, but get the following error:

    $ git review -s
    Problems encountered installing commit-msg hook
    The following command failed with exit code 104
        "GET https://gerrit.onap.org/tools/hooks/commit-msg"

    Does anyone know what I have done wrong? I have tried following the instructions on this page. I'm working in Windows 10.


    Henrik Andersson

    1. Try following this instruction for installing the commit-msg hook:


      In my case, instead of running "git review", I am running the equivalent "git push origin HEAD:refs/for/master" command (under Git Bash on Windows 7) which you can see here: https://gerrit.onap.org/r/Documentation/user-upload.html#push_create


      1. Thank you! This helped me along!


    2. I was ok on windows 10 using python 2.7, pip and git review - this has helped with other issues on linux/osx

      f you get a 404 on commit hooks - reconfigure - https://lists.onap.org/pipermail/onap-discuss/2018-May/009737.html

      curl -kLo `git rev-parse --git-dir`/hooks/commit-msg http://gerrit.onap.org/r/tools/hooks/commit-msg; chmod +x `git rev-parse --git-dir`/hooks/commit-msg
      git commit --amend
      git review -R

  13. I'm trying to set up the IntelliJ Gerrit plugin.  I set the URL to https://gerrit.onap.org ,  user name to my Linux Foundation id, and password to my HTTP password from Gerrit. When I click "Test", I'm getting an 404 error saying it can't find /a/accounts/self.  

    Has anyone else had this issue?  I tried adding my LF id to the URL (https://djtimoney@gerrit.onap.org), and tried using my usual Gerrit password and neither works. 

  14. Hi Dan -  Please try http://gerrit.onap.org/r...It should work

    1. Thanks!  That was my problem.  I had a feeling it was pilot error on my part

  15. settings.xml file

    create an ~/.m2 folder and copy our settings.xml there
    settings.xml -> https://jira.onap.org/secure/attachment/10829/settings.xml
    The most current settings.xml that you should use to build ONAP can be found in the oparent repo at https://git.onap.org/oparent/plain/settings.xml
    https://git.onap.org/oparent/plain/settings.xml -> https://git.onap.org/oparent/plain/settings.xml

    It should be united.

  16. Update: The latest release of OpenJdk 8 (version 1.8.0_191) fixes this issue. Make sure to pull the latest software updates in Ubuntu to get that update.

    There's a bug in the latest OpenJDK 8 Java, which cases all JUnit test cases to fail. I have observed it on a machine running Ubuntu 18.04 on openjdk-8-jre:amd64 8u181-b13-1ubuntu0.18.04.1

    See the following Stack Overflow article:
    and the first answer on the same article.

    The workaround that worked for me was to downgrade the compiler version to openjdk-8-jdk=8u162-b12-1

    sudo dpkg -l | grep openjdk

    Remove all openjdk packages

    sudo apt remove --purge openjdk-8-jdk openjdk-8-jdk-headless openjdk-8-jre openjdk-8-jre-headless

    Now install the previous version of OpenJDK

    sudo apt install openjdk-8-jre-headless=8u162-b12-1 openjdk-8-jre=8u162-b12-1 openjdk-8-jdk-headless=8u162-b12-1 openjdk-8-jdk=8u162-b12-1

    Now your unit tests should run again.

  17. Ubuntu 16.04 TLS bare-metal, trying to deploy SDC locally

    I've ran into problems  mainly because of Docker, installed using this script [1] as in this page Setting Up Your Development Environment [2]:

    • Got an error because DOCKER_HOST wasn't set
      1. solution $ export DOCKER_HOST="unix:///var/run/docker.sock"  and then  $ mvn clean install -P docker
    • I got this error [ERROR] DOCKER> Unable to build image [onap/sdc-onboard-backend] : Unknown flag: chown  [Unknown flag: chown ]
      1. Th reason is the installed Docker version 17.03.2 didn't support the flag chown, whic is supported starting from 17.09.x
      2.  solution $ sudo apt-get upgrade docker-ce  (this isntalled  Docker 19.03.11)
      3. This solved the flage issue
    • I ran into this timeout issue:

    [ERROR] DOCKER> Unable to pull 'onap/base_sdc-sanity:1.4.1' from registry 'nexus3.onap.org:10001' : Get https://nexus3.onap.org:10001/v2/: net/http: TLS handshake timeout (Internal Server Error: 500) [Get https://nexus3.onap.org:10001/v2/: net/http: TLS handshake timeout (Internal Server Error: 500)]

    • Seemed to be a network issue and resolved by retrying couple times and worked out.

    I've posted this here for reference and to help whoever reproduces the same errors.
