SonarQube License-Check

This SonarQube plugin ensures that projects use dependencies with compliant licenses. All dependencies and licenses can be viewed per projects and exported to Excel 2003 XML Format. This enables a simple governance of dependencies and licenses for the whole organization.

Features

Analysis

The plugin scans for dependencies defined in your project including all transitive dependencies.

Currently, supported formats are:

• Maven POM files - all dependencies with scope “compile” and “runtime” are checked
• Gradle projects which use JK1 plugin

• NPM package.json files - all dependencies (except “devDependencies”) are checked

  • Note that transitive dependencies are not scanned unless licensecheck.npm.resolvetransitive is set to true.

    

Project Dashboard

The plugin contains a project dashboard showing a list of dependencies with version and a list of all used licences. Each table shows the status of the license
(allowed, not allowed, not found). You can also export the data to Excel.

Compatibility

This plugin is compatible:

• 6.x version with 9 LTS (>= 9.5) and 10.x
• 5.x version with 8.9 LTS and < 10 (9.x is compatible)
• 4.x version with SonarQube 8.x

For all changes see CHANGELOG.md

Installation

Put the pre-built jar-file (from release downloads) in the directory $SONARQUBE_HOME/extensions/plugins and
restart the server to install the plugin. Activate the rules of this plugin (“License is not allowed”, “Dependency has unknown license”) in your SonarQube quality profiles - otherwise the plugin is not executed.

Configuration

After booting the SonarQube Server with the License-Check Plugin be found in the tab Administration or also in the Configuration -> LicenseCheck drop down menu.

Configuration via Administration Tab

• Within the General Settings and License Check you find the settings for the plugin.

• Within the general settings the plugin can be manually enabled or disabled. By default, it is enabled.

  • Under “Dependency Mapping” you can map a dependency name/key (with regex) to a license, e.g. ^asm:asm$ to “BSD-3-Clause”

  • Under “License Mapping” you can map a license name (with regex) to a license, e.g. .*Apache.*2.* to “Apache-2.0”.

    

  • Under “Licenses” you can allow or disallow licenses globally and add/edit the list of known licenses.

    

  • Under “Project Licenses” you can allow and disallow licenses for a specific project.

    

Configuration via License Menu

Administration -> Configuration(dropdown) -> License Check

• Under “Licenses” you can allow or disallow licenses globally and add/edit the list of known licenses.

  

  

• Under “Project Licenses” you can allow and disallow licenses for a specific project.

  

  

• Under “Dependency Mapping” you can map a dependency name/key (with regex) to a license, e.g. ^asm:asm$ to “BSD-3-Clause”

  

  

• Under “License Mappings” you can map a license name (with regex) to a license, e.g. .*Apache.*2.* to “Apache-2.0”.

  

  

Activation rules in Quality Profile

You have to activate the new rules in a (new) quality profile, for each supported language (Groovy, Kotlin, Java, JavaScript, TypeScript) And you have to use this profile for your project.

Execution

When a project is analyzed using the mvn sonar:sonar in command line the extension is started automatically.

Please make sure to have all dependencies installed before launching the SonarQube analysis. So your complete build
should look something like this:

mvn -B org.jacoco:jacoco-maven-plugin:prepare-agent install org.jacoco:jacoco-maven-plugin:report
mvn -B sonar:sonar

Supported Languages

Groovy, Kotlin, Java, JavaScript, TypeScript

Supported Project Types

Maven + NPM

When using Maven and a Javascript Package Manager, define the sonar.sources property to point to the files which contain dependency information.

...
<properties>
  <sonar.sources>pom.xml,package.json</sonar.sources>
<properties>
...

Maven

Maven works if your project/module has a pom.xml on its root level (running with Maven, Gradle or SonarScanner).

NPM

NPM works if your project/module has a package.json on its root level (running with Maven, Gradle or SonarScanner).

Gradle

Gradle project should use JK1 plugin https://github.com/jk1/Gradle-License-Report

Note: Please check above link for instructions or follow as mentioned below

Step1: Update build.gradle file with following code for using JK1 plugin

import com.github.jk1.license.filter.LicenseBundleNormalizer
import com.github.jk1.license.render.JsonReportRenderer
plugins {
  id 'com.github.jk1.dependency-license-report' version '1.13'
}
licenseReport {
    allowedLicensesFile = new File("$projectDir/src/main/resources/licenses/allowed-licenses.json")
    renderers = new JsonReportRenderer('license-details.json', false)
    filters = [new LicenseBundleNormalizer()]
}

Step 2: Update build.gradle file with following code for using SonarQube plugin

plugins {
    id 'org.sonarqube' version "3.0"
}
jar {
    enabled = true
}
sonarqube {
    properties {
        property "sonar.host.url", "http://localhost:9000"
    }
}

Step 3: run following command to generate your report license-details.json in build/reports/dependency-license

> gradle generateLicenseReport

Step 4: run following command for SonarQube

> gradle sonarqube
