Analyze your code for free with SonarCloud

Using this GitHub Action, scan your code with SonarCloud to detects bugs, vulnerabilities and code smells in 26+ programming languages! In case you want to analyze C and C++ code: rely on our SonarCloud Scan for C and C++ and look at our sample C and C++ project

SonarCloud is the leading product for Continuous Code Quality & Code Security online, totally free for open-source projects. It supports all major programming languages, including Java, JavaScript, TypeScript, C#, C and C++, and many more. If your code is closed source, SonarCloud also offers a free, no-commitment 14-day trial to run private analyses. Start your free trial here: SonarCloud Sign up. With SonarCloud, you also get IDE Support with SonarLint integration to find code issues on the fly. SonarCloud rules and analysis settings synchronize to SonarLint, aligning teams around a single standard of Clean Code.

The repository to analyze is set up on SonarCloud. Set it up in just one click.

Usage

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.organization=<replace with your SonarCloud organization key>
sonar.projectKey=<replace with the key generated when setting up the project on SonarCloud>

# relative paths to source directories. More details and properties are described
# in https://sonarcloud.io/documentation/project-administration/narrowing-the-focus/
sonar.sources=.

The workflow, usually declared in .github/workflows/build.yml, looks like:

on:
  # Trigger analysis when pushing in master or pull requests, and when creating
  # a pull request.
  push:
    branches:
      - master
  pull_request:
      types: [opened, synchronize, reopened]
name: Main Workflow
jobs:
  sonarcloud:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v3
      with:
        # Disabling shallow clone is recommended for improving relevancy of reporting
        fetch-depth: 0
    - name: SonarCloud Scan
      uses: sonarsource/sonarcloud-github-action@master
      env:
        GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
        SONAR_TOKEN: ${{ secrets.SONAR_TOKEN }}

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

uses: sonarsource/sonarcloud-github-action@master
with:
  projectBaseDir: my-custom-directory

In case you need to add additional analysis parameters, you can use the args option:

- name: Analyze with SonarCloud
  uses: sonarsource/sonarcloud-github-action@master
  with:
    projectBaseDir: my-custom-directory
    args: >
      -Dsonar.organization=my-organization
      -Dsonar.projectKey=my-projectkey
      -Dsonar.python.coverage.reportPaths=coverage.xml
      -Dsonar.sources=lib/
      -Dsonar.test.exclusions=tests/**
      -Dsonar.tests=tests/
      -Dsonar.verbose=true

More information about possible analysis parameters is found in the documentation at: https://docs.sonarcloud.io/advanced-setup/analysis-parameters

Secrets

SONAR_TOKEN – Required this is the token used to authenticate access to SonarCloud. You can generate a token on your Security page in SonarCloud. You can set the SONAR_TOKEN environment variable in the "Secrets" settings page of your repository.
GITHUB_TOKEN – Provided by Github (see Authenticating with the GITHUB_TOKEN).

Error cleaning up workspace

In some cases, the checkout action may fail to clean up the workspace. This is a known problem for GitHub actions implemented as a docker container (such as sonarcloud-github-actions) when self-hosted runners are used. Example of the error message: File was unable to be removed Error: EACCES: permission denied, unlink '/actions-runner/_work//project/.scannerwork/.sonar_lock' To work around the problem, sonarcloud-github-action attempts to fix the permission of the temporary files that it creates. If that doesn't work, you can manually clean up the workspace by running the following action:

- name: Clean the workspace
  uses: docker://alpine
  with:
    args: /bin/sh -c "find \"${GITHUB_WORKSPACE}\" -mindepth 1 ! -name . -prune -exec rm -rf {} +"

You can find more info here.

Do not use this GitHub action if you are in the following situations

Your code is built with Maven: run 'org.sonarsource.scanner.maven:sonar' during the build
Your code is built with Gradle: use the SonarQube plugin for Gradle during the build
You want to analyze a .NET solution: Follow our interactive tutorial for GitHub Actions after importing your project directly into SonarCloud
You want to analyze C and C++ code: rely on our SonarCloud Scan for C and C++ and look at our sample C and C++ project
