[Hopefully this isn't a dupe - I got a timeout on posting]
I develop, advise or monitor many branches of our projects and have working copies checked out for several branches at a time. As I use IDEA to open project files in these working copies the IDE caches information for each to improve performance - this works well.
As branches close and new ones appear, my list of working copies changes and projects will be locally deleted. IDEA (v8.1) retains a substantial amount of cached content for, what are now non-existent, working copies.
Is there a way to get IntelliJ to perform garbage collection on cache content for project files that can no longer be found?
This would remove thousands of files and folders and free up several GB of space. At the moment I'm periodically blowing away the entire cache content which bites when I reload project files in branches that are still current.
NB: v7 appeared to slow down more as this cache volume increased - this is less of an issue with v8, possibly evidence of better indexing.
