I have been trying my company's build with the current main trunk, but I'm
seeing significant performance issues. I will try to run a profiler and track
this down more, but I wanted to see if this triggered any thoughts for anyone.
With 0.8, the subset of our build that was mainly compiling java and jarring
everything up took 3:23 (min:sec). With the current trunk, it takes 15:34. I
added a little bit of timing to the trace and at least part of the problem is in
the logic determining if a task is up to date.
ExecutionShortCircuitTaskExecuter line 58 (repositor.getStateFor) is taking over
a minute to execute for some tasks.
These performance problems seem to be worst for subprojects with deep
dependencies. The leaf subprojects (with no dependencies) seem to execute as
fast as before, but some of my root projects (lots of dependencies) are very
slow now. From just trying a breakpoint a few times when it is running slowly,
it seems to often be inside a chain of dependency resolvers when I think the
problem is happening. Here is a typical stack trace:

I had made some changes to add some trace messages to
ExecutionShortCircuitTaskExecuter, so line numbers in that file may be off.
