Execute action on build deletion

[Adri CS]

Hi,

I have a parametrized job that spawns Docker containers when it's running. This job is configured to store only the 10 most recent runs.
I would like to have the containers running for as long as the run that spawned them is stored in Jenkins.

So, the idea would be having something like a Listener that would execute the Docker commands to remove the containers when the build is about to be deleted.

I've thought of using the PostBuild Groovy script plugin to execute a listener and redefine the onDeleted method.

For example:

import hudson.model.Run;
import hudson.model.listeners.RunListener;
import hudson.Extension;

@Extension
public class DeleteListener extends RunListener<Run> {
      @Override
      void onDeleted(Run r) {
         println(r.getNumber())
      }
}

The problem with this approach is that when I execute the build, I get this error:

Groovy script failed:
org.codehaus.groovy.runtime.metaclass.MissingMethodExceptionNoStack: No signature of method: DeleteListener.main() is applicable for argument types: ([Ljava.lang.String;) values: [[]]
Possible solutions: wait(), wait(long), all(), any(), find(), wait(long, int)

I'm not proficient with Java, neither Groovy; so I'm having a hard time understanding this error.

My question is how, if possible, can I execute some system commands whenever a certain build is about to be deleted.

Thanks and kind regards!

I think this is a matter of context. That has to be like a "system" groovy script.

Also, if that doesn't work, you should probably just create a plugin. You have already written what you need, and that will let you manage it cleanlier (writing tests, versioning…).

Cheers

Hi Baptiste,

Thanks for your input.
I will go for the plugin option, as I think this shouldn't be a "system" script, because I only need this behaviour for a very specific jobs.

Thanks and cheers!
