A Java runtime environment is always required to run the scanner that performs (CI-based) analysis. This applies to all scanner variants (CLI, CI-specific, etc.)
The required versions for these runtimes change with successive versions of the scanner. The current requirements and recommendations are:
- You must use either Java 11 or 17.
- You should use at least Node.js 14.17+, though we recommend that you use the latest Node.js LTS, which is currently Node.js 18.
The SonarQube GitHub Action can be configured for different target build technologies (.NET, Gradle, Maven, etc).
If your whole Maven or Gradle build doesn't run on Java 11 or 17, we suggest first to try to base the whole build on one of those two versions of Java. If it's not compatible, then you can override the
JAVA_HOME environment variable just before the analysis step, as shown here:
All VM images available in Azure Pipelines for Microsoft-hosted agents already contain Java 11. There is no further action required. For self-hosted agents, you must ensure that you are using Java 11 or 17. You can either modify your build pipeline to ensure that it runs with Java 11 or 17 by default, or override the
JAVA_HOME environment variable just before running the analysis.
For the specific case of Xamarin, which only allows Java 8, you will need to specify a Java 8 path separately when invoking MSBuild (using, for example,
XAMARIN_JAVA_HOME), and then leave the
JAVA_HOME environment variable for the scanner only.
Multiple base images can be used to run your build with Java 11 or 17, here are some examples:
debian:buster and above
If your build is not compatible with Java 11 or 17, then you can override the
JAVA_HOME environment variable to point to Java 11 or 17 immediately before running the analysis.
You can define a new JDK in Manage Jenkins > Global Tool Configuration, if you have the JDK Tool Plugin installed.
If you are using a declarative pipeline with different stages, you can add a 'tools' section to the stage in which the code scan occurs. This will make the scanner use the JDK version that is specified.
If you are analyzing a Java 8 project, you probably want to continue using Java 8 to build your project. The following example allows you to continue building in Java 8, but will use Java 11 to scan the code:
This example is for Maven but it can be easily modified to use Gradle.
Set Job JDK version
You can easily set the JDK version to be used by a job in the General section of your configuration. This option is only visible if you have configured multiple JDK versions under Manage Jenkins > Global Tool Configuration.
Set 'Execute SonarQube Scanner' JDK version
If you are using the Execute SonarQube Scanner step in your configuration, you can set the JDK for this step in the configuration dialog. By using this approach, you can use JDK 11 or 17 only for the code scanning performed by SonarQube. All the other steps in the job will use the globally configured JDK.
Java 8 projects
Jenkins does not offer functionality to switch JDKs when using a Freestyle project or Maven project configuration. To build your project using Java 8, you have to manually set the
JAVA_HOME variable to Java 11 or 17 when running the analysis.
To do this use the Tool Environment Plugin. This plugin lets expose the location of the JDK you added under Manage Jenkins > Global Tool Configuration. The location of the JDK can then be used to set the
JAVA_HOME variable in a post step command, like this:
The SonarQube GitHub Action already uses Node.js 14+. If you are using the official SonarQube Action, there is nothing further to do. If you are using your own GitHub Action and invoke the SonarScanner manually within that Action, then you should ensure that you are also using at least Node.js 14. See Other cases below.
sonarqube-scan Bitbucket Pipe uses Node.js 14+. We recommend using the latest version of the pipe declaration in your
bitbucket-pipelines.yml. For example:
All VM images available in Azure Pipelines for Microsoft-hosted agents already contain Node.js 14+. There is no further action required. For self-hosted agents you must ensure that you are using Node.js 14+.
The recommended setup for your
sonar-scanner-cli:latest which already uses Node.js 14+. If you are using the recommended setup there is nothing further to do.
You should ensure that the Node.js version used by your Jenkins jobs is at least version 14. If you want to manage multiple versions of Node.js in Jenkins, the NodeJS Jenkins plugin may be useful.
If your build setup falls into one of the following categories, then you will need to ensure that the build environment within which the SonarScanner runs has Node.js 14+ installed:
- Manual invocation of the SonarScanner from the command line.
- Custom local build script invoking the SonarScanner.
- Non-standard use of a CI listed above. For example, using GitHub Actions but not using the provided SonarQube GitHub Action and instead using some other custom Action.
- Use of a CI which is not listed above.
In general, if you are running the SonarScanner command line tool as an executable, then Node.js 14+ needs to be installed on the machine where it is run. Alternatively, if you are using the SonarScanner Docker image, then you just have to ensure that you are using at least version 4.6 of the image, as it already bundles the correct version of Node.js.
