This SonarSource project, available as a GitHub Action, scans your projects with SonarQube Server or Cloud.

SonarQube Server and Cloud (formerly SonarQube and SonarCloud) is a widely used static analysis solution for continuous code quality and security inspection.

It helps developers detect coding issues in 30+ languages, frameworks, and IaC platforms, including Java, JavaScript, TypeScript, C#, Python, C, C++, and many more.

The solution also provides fix recommendations leveraging AI with Sonar's AI CodeFix capability.

To run an analysis on your code, you first need to set up your project on SonarQube Server. Your SonarQube Server instance must be accessible from GitHub, and you will need an access token to run the analysis (more information below under Environment variables).

Read more information on how to analyze your code here.

• Create your account on SonarQube Cloud. Sign up for free now if it's not already the case!
• The repository to analyze is set up on SonarQube Cloud. Set it up in just one click.

Project metadata, including the location of the sources to be analyzed, must be declared in the file sonar-project.properties in the base directory:

sonar.projectKey=<replace with the key generated when setting up the project on SonarQube Server>

# relative paths to source directories. More details and properties are described
# at https://docs.sonarsource.com/sonarqube-server/latest/project-administration/analysis-scope/ 
sonar.sources=.

The workflow, usually declared under .github/workflows, looks like:

on:
  # Trigger analysis when pushing to your main branches, and when creating a pull request.
  push:
    branches:
      - main
      - master
      - develop
      - 'releases/**'
  pull_request:
      types: [opened, synchronize, reopened]

name: Main Workflow
jobs:
  sonarqube:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v4
      with:
        # Disabling shallow clones is recommended for improving the relevancy of reporting
        fetch-depth: 0
    - name: SonarQube Scan
      uses: sonarsource/sonarqube-scan-action@<action version> # Ex: v4.1.0, See the latest version at https://github.com/marketplace/actions/official-sonarqube-scan
      env:
        SONAR_TOKEN: ${{ secrets.SONAR_TOKEN }}
        SONAR_HOST_URL: ${{ vars.SONAR_HOST_URL }}

sonar.organization=<replace with your SonarQube Cloud organization key>

You can change the analysis base directory by using the optional input projectBaseDir like this:

- uses: sonarsource/sonarqube-scan-action@<action version>
  with:
    projectBaseDir: app/src

In case you need to specify the version of the Sonar Scanner, you can use the scannerVersion option:

- uses: sonarsource/sonarqube-scan-action@<action version>
  with:
    scannerVersion: 6.2.0.4584

In case you need to add additional analysis parameters, and you do not wish to set them in the sonar-project.properties file, you can use the args option:

- uses: sonarsource/sonarqube-scan-action@<action version>
  with:
    projectBaseDir: app/src
    args: >
      -Dsonar.organization=my-organization # For SonarQube Cloud only
      -Dsonar.projectKey=my-projectkey
      -Dsonar.python.coverage.reportPaths=coverage.xml
      -Dsonar.sources=lib/
      -Dsonar.tests=tests/
      -Dsonar.test.exclusions=tests/**
      -Dsonar.verbose=true

You can also specify the URL where to retrieve the SonarScanner CLI from. The specified URL overrides the default address: https://binaries.sonarsource.com/Distribution/sonar-scanner-cli. This can be useful when the runner executing the action is self-hosted and has regulated or no access to the Internet:

- uses: sonarsource/sonarqube-scan-action@<action version>
  with:
    scannerBinariesUrl: https://my.custom.binaries.url.com/Distribution/sonar-scanner-cli/

More information about possible analysis parameters can be found:

• in the Analysis parameters page of the SonarQube Server documentation
• in the Analysis parameters page of the SonarQube Cloud documentation

• SONAR_TOKEN – Required this is the token used to authenticate access to SonarQube. You can read more about security tokens in the documentation of SonarQube Server and Cloud. You can set the SONAR_TOKEN environment variable in the "Secrets" settings page of your repository, or you can add them at the level of your GitHub organization (recommended).
• GITHUB_TOKEN – Provided by Github (see Authenticating with the GITHUB_TOKEN).
• SONAR_HOST_URL – this tells the scanner where SonarQube Server is hosted. You can set the SONAR_HOST_URL environment variable in the "Variables" settings page of your repository, or you can add them at the level of your GitHub organization (recommended). Not needed for SonarQube Cloud.
• SONAR_ROOT_CERT – Holds an additional certificate (in PEM format) that is used to validate the certificate of SonarQube Server or of a secured proxy to SonarQube (Server or Cloud). You can set the SONAR_ROOT_CERT environment variable in the "Secrets" settings page of your repository, or you can add them at the level of your GitHub organization (recommended).

Here is an example of how you can pass a certificate (in PEM format) to the Scanner truststore:

- uses: sonarsource/sonarqube-scan-action@<action version>
  env:
    SONAR_TOKEN: ${{ secrets.SONAR_TOKEN }}
    SONAR_HOST_URL: ${{ vars.SONAR_HOST_URL }}
    SONAR_ROOT_CERT: ${{ secrets.SONAR_ROOT_CERT }}

If your source code file names contain special characters that are not covered by the locale range of en_US.UTF-8, you can configure your desired locale like this:

- uses: sonarsource/sonarqube-scan-action@<action version>
  env:
    SONAR_TOKEN: ${{ secrets.SONAR_TOKEN }}
    SONAR_HOST_URL: ${{ vars.SONAR_HOST_URL }} # or https://sonarcloud.io
    LC_ALL: "ru_RU.UTF-8"

This GitHub Action will not work for all technologies. If you are in one of the following situations, you should use the following alternatives:

• Your code is built with Maven. Read the documentation about our SonarScanner for Maven in SonarQube Server and Cloud.
• Your code is built with Gradle. Read the documentation about our SonarScanner for Gradle in SonarQube Server and Cloud.
• You want to analyze a .NET solution. Read the documentation about our SonarScanner for .NET in SonarQube Server and Cloud.
• You want to analyze C or C++ code. Starting from SonarQube 10.6, this GitHub Action will scan C and C++ out of the box. If you want to have better control over the scan configuration/setup, you can switch to:
  • the SonarQube Server Scan for C and C++ GitHub Action, for projects on SonarQube Server
  • the SonarQube Cloud Scan for C and C++ GitHub Action, for projects on SonarQube Cloud - look at our sample C and C++ project.

To provide feedback (requesting a feature or reporting a bug) please post on the SonarSource Community Forum page for SonarQube Server or Cloud.
