Ever since I've installed the new m2e plugin for maven, my Groovy project no longer builds. I'm using the groovy-compiler-plugin as described here. I get the old "plugin execution not covered..." error for the maven-compiler-plugin. I've tried both execute and ignore for the goals "testCompile" and "compile" as described in the error.
I can't use GMaven due to some arcane compiler issues. I also am locked to Maven 2.2.1 due to my company's build process. The old m2eclipse plugin is gone, and the documentation for m2e is atrocious.
I am at my wits end with this. Nowhere else do I see this issue. I can't be the only one.
If I can't find a solution to this very soon, I'm either scrapping maven for some hacked Gradle implementation (though I can't use that either), or I'm moving over to NetBeans, which is not a winning proposition.
As requested, the pom snippet is below.
