Huge discrepancy between batch and Eclipse rebuild times

It definitely shouldn't behave like that. I will try to add some
debugging options so that maybe you can figure out where it is getting
stuck. Did you try getting jvm dump?

Also, things that you should really tell us are:
- eclipse version
- scala plugin version

I assume that the project is not open-source and it is not publicly
available?

Thanks,

I would recommend trying that. You could also enable the heap monitor
in Eclipse to see if you're near the limit. For my medium-size set of
projects, I use -Xmx2500m, which I think is higher than should be but
I had too restart too many times during a coding day otherwise.
