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/).
The solution also provides fix recommendations leveraging AI with Sonar's AI CodeFix capability.
## Requirements
### Server
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](https://docs.sonarsource.com/sonarqube-server/latest/devops-platform-integration/github-integration/introduction/).
### Cloud
* Create your account on SonarQube Cloud. [Sign up for free](https://www.sonarsource.com/products/sonarcloud/signup/?utm_medium=referral&utm_source=github&utm_campaign=sc-signup&utm_content=signup-sonarcloud-listing-x-x&utm_term=ww-psp-x) now if it's not already the case!
* The repository to analyze is set up on SonarQube Cloud. [Set it up](https://sonarcloud.io/projects/create) 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:
### Server
```properties
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:
```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> # 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 }}
```
### Cloud
```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=.
```
The workflow, usually declared under `.github/workflows`, looks like:
```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> # Ex: v4.1.0, See the latest version at https://github.com/marketplace/actions/official-sonarqube-scan
env:
SONAR_TOKEN: ${{ secrets.SONAR_TOKEN }}
```
## Action parameters
You can change the analysis base directory by using the optional input `projectBaseDir` like this:
```yaml
- 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:
```yaml
- 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:
```yaml
- 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:
```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).
- *`GITHUB_TOKEN` – Provided by Github (see [Authenticating with the GITHUB_TOKEN](https://help.github.com/en/actions/automating-your-workflow-with-github-actions/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:
```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"
```
## Alternatives for Java, .NET, and C/C++ projects
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](https://docs.sonarsource.com/sonarqube-server/latest/analyzing-source-code/scanners/sonarscanner-for-maven/) and [Cloud](https://docs.sonarsource.com/sonarqube-cloud/advanced-setup/ci-based-analysis/sonarscanner-for-maven/).
* Your code is built with Gradle. Read the documentation about our SonarScanner for Gradle in SonarQube [Server](https://docs.sonarsource.com/sonarqube-server/latest/analyzing-source-code/scanners/sonarscanner-for-gradle/) and [Cloud](https://docs.sonarsource.com/sonarqube-cloud/advanced-setup/ci-based-analysis/sonarscanner-for-gradle/).
* You want to analyze a .NET solution. Read the documentation about our SonarScanner for .NET in SonarQube [Server](https://docs.sonarsource.com/sonarqube-server/latest/analyzing-source-code/scanners/dotnet/introduction/) and [Cloud](https://docs.sonarsource.com/sonarqube-cloud/advanced-setup/ci-based-analysis/sonarscanner-for-dotnet/introduction/).
* 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++](https://github.com/marketplace/actions/sonarqube-scan-for-c-and-c) GitHub Action, for projects on SonarQube Server
* the [SonarQube Cloud Scan for C and C++](https://github.com/marketplace/actions/sonarcloud-scan-for-c-and-c) GitHub Action, for projects on SonarQube Cloud - look at [our sample C and C++ project](https://github.com/sonarsource-cfamily-examples?q=gh-actions-sc&type=all&language=&sort=).
