Re: [jira] Commented: (MSOURCES-8) maven-source-plugin causes generate-sources phase to execute twice

[Grzegorz Slowikowski <gs...@gmail.com>]

Hi

This is not the first problem with cycle forking. The others I know are:
- test coverage checking with clover plugin
- jspc plugin (codehaus mojo) - forking was removed

Do you have any idea, what to do with it?
