Recompile gwt on no changes

[tbroyer]

Any idea why the sources jar has been rebuilt? It shouldn't be if there are no changes (at least according to documentation)

Maybe you could post the full log as gist?

Full gist. I just change plugin version to 1.0-rc-6. No effect
upd: full log is huge and gist doesn't support it. There is end of output https://gist.github.com/zufarfakhurtdinov/429bff8f28fe714c0ea0

This is the culprit: https://gist.github.com/zufarfakhurtdinov/a8fe415308f83b33e972#file-gistfile1-txt-L1098

[DEBUG] isUp2date: false (Resource with unknown modification date found.)

Now we'd need to understand which resource has a zero modification time. I'll see if I reproduce locally and will try to debug it.

OK, so the problem is that the maven-compiler-plugin:3.2 creates directory target/generated-sources/annotations and adds it as a source root, and maven-source-plugin (through maven-archiver → plexus-archiver → plexus-io) treats an empty directory as "having changed" (and that directory is always empty as there's no annotation processor involved).

Using maven-compiler-plugin:3.1 (which won't add target/generated-sources/annotations to the source roots; see https://issues.apache.org/jira/browse/MCOMPILER-157) will workaround the problem (until you need to use an annotation processor, in which case you should try maven-compiler-plugin:3.5.1 which should behave correctly/sensibly).

Fixed in 2247532, thanks for the report.
