Gracefully stopping a build step (plugin) on build abort

I have a plugin in Jenkins that operates a remote server via rest.
How can I send one last request to the server on build abort? Thus, gracefully finishing the work of the plugin?

The only reference to the 'Abort sequence' that I found is this. Which makes me think that the procedure is very rough, and that I can't catch the signal before it terminates the child (my plugin).

Why is my Jenkins build taking so long?

Fortunately, the most common reasons your Jenkins instance is slow are easy to diagnose and correct: Non-performant plugins. Poorly tuned JVM arguments. Non-optimal garbage collection.

I have a similar need, which I solved with the PostBuildScript Plugin.

I choose to run a build step, but you can run several other options. Very easy to use. I have a script I must run regardless of how the build ended (success, fail or abort). It works great for me.

I hope this helps.
