we have run into this issue as well. There are AFAIK two options, none
of which is great:

- Use Maven profiles to make test execution and obfuscation mutually
exclusive, e.g., only obfuscate when using -Prelease and then
-DskipTests. Unfortunately, your tests then won't catch breakage due to
misconfigured obfuscation anymore.

- Use Guava's @VisibleForTesting or a similar annotation to selectively
exclude some methods from obfuscation, effectively making your test API
entrypoints. This of course has the drawback that the more you test the
less you obfuscate.

If there's a better solution then I would like to hear of it, of course.

Hope this helps anyway.

Andreas
