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.
Table of Contents |
---|
Create a Linux Foundation Account
...
Follow the instructions on the identity portal to create a Linux Foundation account and get access to the OpenECOMP ONAP Gerrit instance. Then verify
Verify that you can log in at https://gerrit.openecomponap.org/ and that you can see the OpenECOMP ONAP list of repositories.
...
Basic Setup
...
Git
...
Install git for your OS in accordance with https
To install git-review on Linux (Ubuntu), type the following command.
sudo apt-get install git-review
Windows Setup
Installing Git
Install Git on your client, visit: https://www.atlassian.com/git/tutorials/install-git, and download the appropriate installation image for your host. Execute the installation script.
Include the "Git Bash" and "Git GUI" components (this is the default). For example, during the Windows installation, 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.
Windows Setup for git-review
Follow those steps if you are a Windows user and need to interact with Gerrit; it will help you when you install git-review on your system.
Preliminary Step: Install Putty and Generate a Putty Key
NOTE: If you already have keys registered with putty, skip this section.
- Ensure you have the complete putty suite installed. You should have pageant.exe, plink.exe and puttygen.exe.
- Generate a key with puttygen. Choose a passphrase, then select "Save private key" and choose a target; also "Save public key" and select a target. It is recommended to use file names containing "private" and "public" for the keys as both will end in .ppk.
- Start pageant if not started, then add your newly generated private key.
- Under the control panel > system > advanced system properties > environment variables, add a GIT_SSH entry (if not present) and point to plink.exe.
- When done, start a command line (cmd.exe) and run 'env'; the newly added environment variable should appear.
- In your Gerrit profile, add the public key. Also, 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 Python and git-review on Windows
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.
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:
...
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
Code Block | ||||||

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. |

Optional Tools & Utilities
Python
Info |
---|
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.
|
---|
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 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.remote)
Info |
---|
The git Git and git-review installation steps above are described 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):
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.
Selecting a connection method (SSH or HTTPS)
Once Git/Gerrit is installed, you will need to select a connection method to the remote server.
We recommend using SSH in which case you need to register your public key in your account settings in Gerrit.
If you choose to use HTTP/HTTPS, you'll need to generate an access password. To do so:
In your Gerrit account settings, 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.openecomp.org/r/a/mso/ ': Unknown SSL protocol error in connection to gerrit.openecomp.org:443 error: Could not fetch gerrit
Regenerating a password will most likely solve the connectivity issue. Sometime, the Gerrit interface on HTTPS might be temporarily faulty, so retries might be needed.
Cloning the Repository by Using the Command Line
...
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.
Working with a Proxy
For people working with a proxy, you might have proxy issues connecting to Linux Foundation website. To avoid the connection issue, you shall 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 shall putone.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>
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.
