This won't allow you to exclude sources in generated_src_dirs (it'll actually
work if the files exist, but won't work if you rm -rf out first).

[jbudorick, 2014/09/16 02:50:41]

Hm, I hadn't thought of people trying to exclude things from generated_src_dirs.
Thoughts on how to handle that case?

[cjhopman, 2014/09/15 22:27:37]

Does this have to be '^' because of the 'java_sources!'?

[jbudorick, 2014/09/16 02:50:41]

Yep. Exclusion happens between PHASE_LATE (>) and PHASE_LATELATE (^).
