SonarQube [Server](https://www.sonarsource.com/products/sonarqube/) and [Cloud](https://www.sonarsource.com/products/sonarcloud/) (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](https://www.sonarsource.com/knowledge/languages/).
## A GitHub Action for SonarQube
This GitHub Action integrates continuous code quality and security analysis directly into your workflow. It scans your project with either [SonarQube Server](https://www.sonarsource.com/products/sonarqube/) or [SonarQube Cloud](https://www.sonarsource.com/products/sonarcloud/), helping you catch bugs, security vulnerabilities, and code smells automatically within your CI/CD pipeline. **This action is the official method for scanning C, C++, Objective-C, and Dart projects via GitHub Actions.**
The solution also provides fix recommendations leveraging AI with Sonar's AI CodeFix capability.
> [!NOTE]
> This action now supports and is the official entrypoint for scanning C, C++, Objective-C and Dart projects via GitHub actions.
### What is SonarQube?
[SonarQube Server](https://www.sonarsource.com/products/sonarqube/) and [SonarQube Cloud](https://www.sonarsource.com/products/sonarcloud/) are widely used static analysis solutions for continuous code quality, security inspection, and fix remediation.
The platform supports over in 30+ languages, frameworks, and IaC platforms, including Java, JavaScript, TypeScript, C#, Python, C, C++, and [many more](https://www.sonarsource.com/knowledge/languages/).
## Requirements
## Quick Start
### Server
### 1. Prerequisites:
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**).
You must have a project already set up on SonarQube Cloud or SonarQube Server. This action performs the analysis, but the project must exist on the platform to receive the results.
For more information, see [Key Requirements](#key-requirements).
### 2. Required variables:
The action needs two key variables to connect to the SonarQube instance and run the analysis. These should be stored as GitHub secrets or variables for security.
`SONAR_TOKEN` : The authentication token required to access the SonarQube instance. This is a mandatory secret for all use cases.
`SONAR_HOST_URL` : The URL of the SonarQube Server. This is required for self-hosted SonarQube Server but not needed for SonarQube Cloud.
For more information, see [Configuration](#configuration).
### 3. Quick Start Workflow Example (for SonarQube Cloud)
Create or update your CI pipeline to run the scan action:
```yaml
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 or sha1> # Ex: v4.1.0 or sha1, See the latest version at https://github.com/marketplace/actions/official-sonarqube-scan
env:
SONAR_TOKEN: ${{ secrets.SONAR_TOKEN }}
```
Create a configuration file in the root directory of the project and name it `sonar-project.properties`:
```properties
sonar.organization=<replace with your SonarQube Cloud organization key>
sonar.projectKey=<replace with the key generated when setting up the project on SonarQube Cloud>
# relative paths to source directories. More details and properties are described
# at https://docs.sonarsource.com/sonarqube-cloud/advanced-setup/analysis-scope/
sonar.sources=src
```
For other workflows, see [Workflow Examples](#workflow-examples).
## Important: Special Cases and alternatives

## Usage
## Configuration
### Action parameters
#### `projectBaseDir`
You can change the analysis base directory by using the optional input `projectBaseDir` like this:
```yaml
- uses: SonarSource/sonarqube-scan-action@<action version or sha1>
with:
projectBaseDir: app/src
```
#### `scannerVersion`
In case you need to specify the version of the Sonar Scanner, you can use the `scannerVersion` option:
```yaml
- uses: SonarSource/sonarqube-scan-action@<action version or sha1>
with:
scannerVersion: 6.2.0.4584
```
#### `args`
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:
```yaml
- uses: SonarSource/sonarqube-scan-action@<action version>
with:
projectBaseDir: app/src
args: >
-Dsonar.organization=my-organization # For SonarQube Cloud only
"-Dsonar.projectName=My Project"
-Dsonar.projectKey=my-projectkey
-Dsonar.python.coverage.reportPaths=coverage.xml
-Dsonar.sources=lib/
-Dsonar.tests=tests/
-Dsonar.test.exclusions=tests/**
-Dsonar.verbose=true
```
> [!NOTE]
> In version 6, the way the `args` option is handled has been changed to prevent command injection.
> As a result, we no longer support the full bash syntax.
> This means there is now a much more restricted use of quoting and escaping compared to older versions of the action.
> Example:
> ```yaml
> with:
> args: >
> -testing test
> -valid=true
> --quotes "test quotes" "nested \'quotes\'"
> -Dsonar.property="some value"
> "-Dsonar.property=some value"
> ```
> will be parsed as the following array of strings:
> ```
> [
> '-testing',
> 'test',
> '-valid=true',
> '--quotes',
> 'test quotes', # Surrounding quotes are removed
> 'nested \'quotes\'',
> '-Dsonar.property="some value"', # Internal quotes are NOT removed, contrary to the bash syntax
> '-Dsonar.property=some value', # This is the proper way to pass scanner arguments with spaces
> ]
> ```
#### `scannerBinariesUrl`
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:
```yaml
- 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](https://docs.sonarsource.com/sonarqube-server/latest/analyzing-source-code/analysis-parameters/) of the SonarQube Server documentation
* in the [Analysis parameters page](https://docs.sonarsource.com/sonarqube-cloud/advanced-setup/analysis-parameters/) of the SonarQube Cloud documentation
### Environment variables
- `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](https://docs.sonarsource.com/sonarqube-server/latest/user-guide/managing-tokens/) and [Cloud](https://docs.sonarsource.com/sonarqube-cloud/managing-your-account/managing-tokens/). 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).
- `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:
```yaml
- 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:
```yaml
- 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"
```
## Workflow Examples
### For SonarQube Cloud
Project metadata, including the location of the sources to be analyzed, must be declared in the file sonar-project.properties in the base directory:
```properties
sonar.organization=<replace with your SonarQube Cloud organization key>
sonar.projectKey=<replace with the key generated when setting up the project on SonarQube Cloud>
# relative paths to source directories. More details and properties are described
# at https://docs.sonarsource.com/sonarqube-cloud/advanced-setup/analysis-scope/
sonar.sources=src
```
#### Standard Projects
For projects that:
- do not contain C, C++, or Objective-C, and
- for C, C++, Objective-C projects that don't use [Build Wrapper](https://docs.sonarsource.com/sonarqube-cloud/advanced-setup/languages/c-family/prerequisites/#using-build-wrapper)
the workflow, usually declared under `.github/workflows/build.yml`, looks like the following:
```yaml
