I'm trialling IDEA as an alternative to Netbeans and have created a project from existing sources. One module in this project is maintained under Mercurial. The project builds ok, but when I select the Mercurial/Commit directory in the drop-down menu on the module, it tells me there is "Nothing to commit - no changes detected". On the command line I can use hg status and see there are numerous changes. I can also use Mercurial/Show history in IDEA and see the correct log for the repository.
I have another module in the same project maintained with Git, and it is behaving as expected.
Any suggestions on how to make this work?
