We've got a project which is about 10.000 classes when compiled.
Compilation takes a very long time (15 to 30 minutes or more), compared to IDEA 12.
Especially the 'Writing classes...' part.
We've had a similar issue with IDEA 12, but this was solved by unchecking the 'Use external build' option in the compiler settings.
This option is no longer available in IDEA 13.
I've tried using the eclipse compiler, but this resulted in some generics related compilation errors which we don't have with javac.
Is there anything we can do about this? Is there still some way to disable the external build?
Edit: I've just recompiled an older patch version and it took 50min... (while less than 5min in IDEA12)
