Here is what I did. I do not know if all the steps are necessary to reproduce the bug, but the bug is reproducible:
1. Check out a multi-level project
2. Install the parent with -N
3. Go into one of the children projects and then run eclipse:eclipse
4. You will see a folder named $
when execution is finished.
Works fine in 2.0.9 and fails with 2.0.10. This is definitely a regression.
