Catching InterptedException Within Builder Plugin (Java)

[Tal Yanai]

Hi,

Is there any way to catch an InterptedException within the Builder Perform method?

I'm trying to catch the event of aborting a build.

Thanks,

Tal.

Read about how Jenkins aborts a build here  https://www.jenkins.io/doc/book/using/aborting-a-build/

It is somewhat OS dependent. I was looking for the same thing on a windows 10 agent but TerminateProcess is a non-interruptible function.

I heard that some folks had tried in-memory patching on the fly, sounds a bit dicey.

A watchdog or dead man's handle type of approach might be more robust.

If Jenkins had an abort hook built in to ensure equipment is returned to a safe state but once you put the hook in, it is also open to misuse.

If Jenkins had a 'build other job on abort' type of thing that design introduces all sorts of potential race conditions and cascading errors.

Don't know about your use case but I settled on putting the 'return to safe state' function into the equipment under test and triggered by an over boundary condition. Which is where it should have been in the first place.

I can't think of a way to do this without making Jenkins less robust, and I love the robustness of Jenkins.

Would like to hear if others have the same type of requirement for an action when a Jenkins job is aborted.
