I’m currently using SonarQube Server 10.3 and running code scans from Jenkins using the Sonar Jenkins plugin. I install the SonarScanner v.6.2.1 as a tool in Jenkins, which then downloads directly the zip file with the scanner binaries into the agent. The version includes the Java runtime in it, so it uses it to run the scan.
The problem I’m having is that, one of the agents uses alpine as the base image, which is incompatible with the Java runtime included in the bundle. I’ve installed Java in the alpine image as a test but I cannot get the scanner to use that version instead of the embedded one. I’ve tried setting the SONAR_JAVA_PATH and JAVA_PATH as environment variables but it’s still not working. I always get an error like the following:
/home/jenkins/agent/tools/hudson.plugins.sonar.SonarRunnerInstallation/SonarScanner6/sonar-scanner-6.2.1.4610-linux-x64/bin/sonar-scanner: exec: line 66: /home/jenkins/agent/tools/hudson.plugins.sonar.SonarRunnerInstallation/SonarScanner6/sonar-scanner-6.2.1.4610-linux-x64/jre/bin/java: not found
Is there any way to force the scanner to use the local runtime?
Thanks.
yes, I looked into that doc but it didn’t work. In the meantime, I think I found what was causing the issue. I haven’t tested it yet.
According to the discussion in this other thread, and from what I saw in the code, you need to use a specific bundle of the scanner or modify a specific file in order for the scanner to not use the embedded runtime. In the thread, there is a link to a documentation page but it doesn’t exist anymore.
And a pipeline like this (demonstrative purposes only, continue to refer to the docs):
pipeline {
agent any
stages {
stage('SonarQube analysis') {
steps {
script {
scannerHome = tool 'SQScanner621'// must match the name of an actual scanner installation directory on your Jenkins build agent
}
sh "${scannerHome}/bin/sonar-scanner"
}
}
}
}
the logs show that a version without any embedded JRE is downloaded.

Indeed, this is my local Java version.

Yes, using the installer that downloads the bundle from Maven requires a local runtime as it doesn’t include it. But, in my case, I’m using the zip installer pointing to the linux bundle that comes with the runtime as I don’t want to depend on it. But that one doesn’t work when using alpine as it doesn’t include the correct libraries the runtime is compiled with. That’s why I was trying to find a way to use the local Java whenever the embedded runtime didn’t work without the need to use a different scanner bundle.
So, for those Jenkins agents that use alpine, based on what’s described in the post I linked, I’ll be forced to use the installer you used in your example and add something in my code (I’m using a shared library written in Groovy) to distinguish between the 2 cases.
