Java demand in Run Code Analysis job in Azure DevOps

[sudo-md (Maikel)]

Hi there,

we are currently using the SonarQube plugin in our pipeline.

This suggestion is concerning the Run Code Analysis job, available in Azure DevOps.

Once the job is added to the build, the demand “java exists” is added to the agent. In the transition from JDK to OpenJDK we found that the installation of OpenJDK doesn’t create the demand java. However, because it’s necessary for the Run Code Analysis job our agent can’t execute the entire build.

Is it possible to change this demand? For example, the JAVA_HOME environment variable is present with the OpenJDK installation. This demand is available for the agent to use.

Greetings,

This thread should help you understand why this is going on:

Azure DevOps hosted build “java” demanded capability not present

Hi @ajwgregg. Welcome to the community. To answer your first question, Java is required on the build agent because the Sonar scanner and language plugins are written in Java and they run on the build agent. The reason installing the OpenJDK didn’t fix your build is because of this bug in the Azure DevOps Windows build agent, which we can’t fix or work round in our extensions. I’ve just pinged Microsoft to ask about the status of the bug. The discussions about the bug and possible fixes in the…

Hi Colin,

thank you for your reply.

My request is not entirely what you’re suggesting. What we would like is that the demand doesn’t strictly look at java only, so for instance java or java_home as demand.

@sudo-md the community post @Colin referred you to explains why we can’t change the demands in our Marketplace extension. To summarise, changing the demand to only java_home would break some use cases, and we can’t demand java or java_home as that isn’t supported by Microsoft.
