Since this is common for all OS, we will also use it to generate our SSH keys as well :
Code Block |
---|
ssh-keygen |
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.
Java
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
Maven
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:
Code Block |
---|
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 :
Code Block |
---|
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

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
Expand |
---|
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' 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)
Expand |
---|
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. |

|
---|
git-review (optional)
In a shell, type the following command (assumes you installed python above) :
Code Block |
---|
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)

Code Block |
---|
git config --global user.email <your_LF_account_email>
git config --global --add gitreview.username <your_LF_user_name> |
Configure git review
Code Block | ||
---|---|---|
| ||
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:
Code Block |
---|
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.
Node-JS
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
Code Block |
---|
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.
Start the server by running:
Code Block language bash $ docker run -d --name sonarqube -p 9000:9000 sonarqube:latest
- Log in to http://localhost:9000 with System Administrator credentials (login=admin, password=admin).
- 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.

Hack oparent to fix "curly bracket" issue
Expand |
---|
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.

Installing Git
To install Git on your client, visit: https://www.atlassian.com/git/tutorials/install-git, and download the appropriate installation image for your host. Once downloaded, execute the installation script ("open" the .msi file).
During installation, you will see the following dialog box. Include the "Git Bash" and "Git GUI" components (this is the default).To do this, leave the following boxes checked:
If you intend to type Git commands from the Windows Command Prompt, leave the default setting for adjusting the PATH environment:
The repositories use Unix-style line-feed for line termination, so on your windows Git client, select the conversion option:
Select the following option based on your own preference (non-default shown, so 'winpty' is not required):
Choose the defaults here:
The installer lets you choose the experimental 'difftool'; either choice will work. Continue with the installation dialogs until the installation is complete.
Install Python on Windows (optional) - required to get pip for git-review
Not all components require Python for development. See the documentation for your component in the Development Guides section. (Note: the "node-gyp" tool requires Python.)
Download Python version 2.7.10:
Execute the install file that you just downloaded. (You must have administrative privileges.) During installation, select "Add python.exe to Path", overriding the default setting. Also, be sure to install "pip" (this is the default).
Continue with the installation until it is completed.
Set up Git review and Configure Git
Run Git Bash as Administrator (for example, in Windows 10, use the Windows menu, scroll to the Git directory, right-click on Git-bash, and select "Run as administrator":
Within Git Bash, type the following command: assumes you already installed python above
$ pip 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), otherwise you will get the error message UnboundLocalError: local variable 'no_git_dir' referenced before assignment.

Install Putty and Generate Keys
Info |
---|
An alternate method for creating public and private keys, without using PuTTY, is given here: https://help.github.com/articles/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent/ |
Info |
---|
If you already have keys registered with PuTTY, skip this section. |
PuTTY is a terminal emulator that uses Secure SHell (SSH) to communicate with a host. You need to install PuTTY in order to create a public/private encryption key pair. This pair of keys enables Git to communicate securely with the repositories.
To install PuTTY, visit, www.putty.org and follow the links to the appropriate Windows installation for your machine (32-bit or 64 bit). The downloaded file will be named putty-0.67-installer.msi
or the like.
Execute the .msi
file. Use all the default settings, thereby ensuring that you will install pageant.exe
, plink.exe
, and puttygen.exe
.
Generate Public and Private Keys
OSX
...
ssh-keygen -t rsa
...
The puttygen
utility, installed with putty
, generates public and private keys used for secure communication with Gerrit.
Info |

You should execute |
To do this, right-click on C:\Program Files (x86)\PuTTY\puttygen.exe
and select Run as Administrator:
Answer "Yes" to the User Account Control challenge. Then click the "Generate" button in the puttygen window. puttygen will ask you to move your mouse over its dialog box to generate random seed bits. After it has computed a public key, it will display a dialog box resembling the following:
If you want to edit this key pair in the future, create a text file containing a short phrase, called a "passphrase". Copy and paste this passphrase into the "Key passphrase" and "Confirm passphrase" lines, then select "Save public key" and choose a filename (e.g. public.txt
); also "Save private key" and choose another filename (e.g. private.ppk
). Since you ran puttygen
as Administrator, the files are visible to Windows Explorer.
Close puttygen
.
Load Your Private Key Into Pageant
Pageant is an SSH authentication agent. It holds your private keys in memory, already decoded, so that you can use them often without needing to type a passphrase.
To load your private key into pageant
, right-click on the private key file (e.g. private.ppk
in this example), and select Load into pageant
:
This action not only loads private.ppk
into pageant, but also starts pageant if it is not already running. You will be prompted for the passphrase that you entered into puttygen
when you created the key. If successful, pageant will load the key without further interaction.

If you are using IntelliJ to do Java compilations, download the IntelliJ installation image from https://www.jetbrains.com/idea/. The installation dialog gives you the opportunity to associated IntelliJ with file type .java, among others. Installation takes several minutes.
When you start your first IntelliJ project, you will need to specify the Java Software Development Kit (SDK) as the project's. If you do not have the Java SDK installed on your machine, you can download it from within IntelliJ by selecting Maven as the New Project type and clicking on "Download SDK": (Or, visit http://www.oracle.com/technetwork/java/javase/downloads/index.html).
Installing the Gerrit plugin in IntelliJ
Open File -> Settings -> Plugins of IntelliJ, and click on the Browse repositories... button.
In the new window, search for Gerrit, click Install to install the plugin, and finally restart IntelliJ.
To verify whether the Gerrit plugin is installed successfully, you can click File -> New -> Project from Version Control and verify whether Gerrit is present.
Other Tools
The component you are working on may require additional tool installations, see the relevant section under Development Guides.
Maven
For console (mvn) Install maven 3.3.3+ (currently 3.5.0) - as 3.2.x will have issues with the ODL certificate not matching
Will also fix
hostname in certificate didn't match: <nexus.opendaylight.org> != <logs.opendaylight.org> OR <logs.opendaylight.org> |

Selecting a connection method
Once Git is installed, you will need to select a connection method to the Gerrit host, https://gerrit.onap.org/.
We recommend using SSH, in which case you need to register your private key in your account settings on the Gerrit host. However, if you are using a Virtual Private Network (VPN), you will require the HTTPS method, since most VPNs won't allow an ssh connection.
...
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.
In the Settings window, select SSH Public Keys, and then click Add Key... .
...
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":
The icon at the right of the generated password allows you to copy the generated password to your clipboard, it will be needed when you interact with Git/Gerrit.
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.
Working with a Proxy
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.
Building all ONAP projects
Maven Example 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
Save this Maven settings.xml as your ~/.m2/settings.xml
Some notes on the settings.xml:
- The use of the staging repo has been eliminated with the rollout of https://wiki.onap.org/display/DW/Independent+Versioning+and+Release+Process in Sept. 2017.
If you are behind a proxy you can add a proxy section to your settings.xml
