Light Way to failOnModifications

[mschmiedel]

I am in the need to get Jenkins to be "UNSTABLE" when japicmp finds violations instead of failing the build. Problem is, that I have no way of calling japicmp Task directly from a Jenkinsfile or something similar separately from the build (corporate design).

What I want to do, is to be able to manually get a value from the task in the doLast closure which tells me if there are violations. This way I can signal Jenkins from Gradle to set the build UNSTABLE with a reason.

Is there a way to get this to work?
