Sonarqube Community Branch Plugin

A plugin for SonarQube to allow branch analysis in the Community version.

Support

This plugin is not maintained or supported by SonarSource and has no official upgrade path for migrating from the SonarQube Community Edition to any of the Commercial Editions (Developer, Enterprise, or Data Center Edition). Support for any problems is only available through issues on the Github repository or through alternative channels (e.g. StackOverflow) and any attempt to request support for this plugin directly from SonarSource or an affiliated channel ( e.g. Sonar Community forum) is likely to result in your request being closed or ignored.

If you plan on migrating your SonarQube data to a commercial edition after using this plugin then please be aware that this may result in some or all of your data being lost due to this compatibility of this plugin and the official SonarQube branch features being untested.

Compatibility

Use the following table to find the correct plugin version for each SonarQube version

SonarQube Version	Plugin Version
10.6	1.22.0
10.5	1.20.0
10.4	1.19.0
9.9 (LTS)	1.14.0

Older versions are listed on the Github release page but are no longer supported.

Features

The plugin is intended to support the features and parameters from the SonarQube documentation.

Installation

Manual Install

Please ensure you follow the installation instructions for the version of the plugin you're installing by looking at the README on the relevant release tag.

Either build the project or download a compatible release version of the plugin JAR .

1. Copy the plugin JAR file to the extensions/plugins/ directory of your SonarQube instance
2. Add -javaagent:./extensions/plugins/sonarqube-community-branch-plugin-${version}.jar=web to the sonar.web.javaAdditionalOpts property in your Sonarqube installation's conf/sonar.properties file, e.g. sonar.web.javaAdditionalOpts=-javaagent:./extensions/plugins/sonarqube-community-branch-plugin-${version}.jar=web where ${version} is the version of the plugin being worked with. e.g 1.8.0
3. Add -javaagent:./extensions/plugins/sonarqube-community-branch-plugin-${version}.jar=ce to the sonar.ce.javaAdditionalOpts property in your Sonarqube installation's conf/sonar.properties file, e.g. sonar.ce.javaAdditionalOpts=-javaagent:./extensions/plugins/sonarqube-community-branch-plugin-${version}.jar=ce
4. Start Sonarqube, and accept the warning about using third-party plugins

Docker

The plugin is distributed in the mc1arke/sonarqube-with-community-branch-plugin Docker image, with the image versions matching the up-stream Sonarqube image version.

Note: If you're setting the SONAR_WEB_JAVAADDITIONALOPTS or SONAR_CE_JAVAADDITIONALOPTS environment variables in your container launch then you'll need to add the javaagent configuration to your overrides to match what's in the provided Dockerfile.

Docker Compose

A docker-compose.yml file is provided. It uses the env variables available in .env.

To use it, clone the repository and execute docker-compose up. Note that you need to have docker-compose installed in your system and added to your PATH

Kubernetes with official Helm Chart

When using Sonarqube official Helm Chart, you need to add the following settings to your helm values, where ${version} should be replaced with the plugin version (e.g. 1.11.0). Beware of the changes made in helm chart version 6.1.0:

helm chart version < 6.1.0

plugins:
  install:
    - https://github.com/mc1arke/sonarqube-community-branch-plugin/releases/download/${version}/sonarqube-community-branch-plugin-${version}.jar
  lib:
    - sonarqube-community-branch-plugin-${version}.jar
jvmOpts: "-javaagent:/opt/sonarqube/lib/common/sonarqube-community-branch-plugin-${version}.jar=web"
jvmCeOpts: "-javaagent:/opt/sonarqube/lib/common/sonarqube-community-branch-plugin-${version}.jar=ce"

helm chart version >= 6.1.0

plugins:
  install:
    - https://github.com/mc1arke/sonarqube-community-branch-plugin/releases/download/${version}/sonarqube-community-branch-plugin-${version}.jar
jvmOpts: "-javaagent:/opt/sonarqube/extensions/plugins/sonarqube-community-branch-plugin-${version}.jar=web"
jvmCeOpts: "-javaagent:/opt/sonarqube/extensions/plugins/sonarqube-community-branch-plugin-${version}.jar=ce"

Issues with file path with persistency

If you set persistence.enabled=true on SonarQube chart, the plugin might be copied to this path, based on the helm chart version, mentioned above (${plugin-path} equals lib/common or extensions/plugins):

/opt/sonarqube/${plugin-path}/sonarqube-community-branch-plugin-${version}.jar/sonarqube-community-branch-plugin-${version}.jar

instead of this:

/opt/sonarqube/${plugin-path}/sonarqube-community-branch-plugin-${version}.jar

As a workaround either change the paths in the config above, or exec into the container and move file up the directory to match the config.

Configuration

Global configuration

Make sure sonar.core.serverBaseURL in SonarQube /admin/settings is properly set in order to for the links in the comment to work.

Set all other properties that you can define globally for all of your projects.

How to decorate a Pull Request

In order to decorate your Pull Request's source branch, you need to analyze your target branch first.

Run analysis of branches

If the scan is being run from a CI supporting auto-configuration then the scanner can be launched without any branch parameters. Otherwise, the analysis needs the following setting: sonar.branch.name = branch_name (e.g master)

Run analysis of the PR branch

Carefully read the official SonarQube guide for pull request decoration

In there you'll find the following properties that need to be set, unless your CI support auto-configuration.

sonar.pullrequest.key = pull_request_id (e.g. 100)
sonar.pullrequest.branch = source_branch_name (e.g feature/TICKET-123)
sonar.pullrequest.base = target_branch_name (e.g master)

⚠️ There must not be any sonar.branch properties like sonar.branch.name arguments set when you analyze a pull-request. These properties indicate to sonar that a branch is being analyzed rather than a pull-request so no pull-request decoration will be executed.

Serving images for PR decoration

By default, images for PR decoration are served as static resources on the SonarQube server as a part of Community Branch Plugin.

If you use a SonarQube server behind a firewall and/or PR service (Github, Gitlab etc.) doesn't have access to SonarQube server, you should change Images base URL property in General > Pull Request settings.

Anyone needing to set this value can use the URL https://raw.githubusercontent.com/mc1arke/sonarqube-community-branch-plugin/master/src/main/resources/static, or download the files from this location and host them themself.

Building the plugin from source

If you want to try and test the current branch or build it for your development execute ./gradlew clean build inside of the project directory. This will put the built jar under libs/sonarqube-community-branch-plugin*.jar
