Set up SonarLint towards ONAP for IntelliJ

Prerequisites

• 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

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'
4. Ensure sonarcloud is selected  and click [Next]
5. Click [Create Token]
6. Select GitHub, logon and follow the GitHub wizard to create a Token
7. Copy Token into IntelliJ wizard
8. Click [Next] (might have to wait a little while your data is being downloaded)
9. Select 'Open Network Automation Platform (ONAP)' from 'Your Organizations' and click [Next]
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) 'Binfd 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 

Python

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

Add python binary to Path.

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

git-review

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)

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.

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 

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:

$ docker run -d --name sonarqube -p 9000:9000 sonarqube:latest

...

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

Other Tools

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

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.
