maven - Can a Jenkins build be failed for coverage going down?

Question

I've seen a number of posts on making a Maven-backed Jenkins build fail for a given project if a coverage threshold isn't met i.e. coverage must be at least 80% or the build fails.

I'm wondering if there is a way to configure Jenkins to fail a build if the coverage is lower than the last build i.e. if the coverage for build N is 20%, and N+1 is 19%, then the build fails. I don't want to put in an explicit threshold, but I want the coverage to stay steady or get higher over time.

Answer 1

Save last coverage percentage on the side. Use Groovy script (run via Groovy Plugin) that taps into Jenkins Java API to compare current coverage level with previous one and fail the build if it drops. If you seriously decide to go this way I can provide more details and code samples.
