How to clean up .metadata [message #267141]

Is there a way to clean up .metatdata in a workspace? I have noticed it's
about 2/3 of my whole workspace now. Thanks.

Fchen,
if you look into .metadata/plugins, which folders use the most space?

For me it's usually:
- org.eclipse.jdt.core - uses lot of space for Java search index. This
is a price for fast Ctrl+Space, Ctrl+Shift+T, etc.
- org.eclipse.pde.core - if you do Plug-in development, launch
configurations may take a lot of space. Usually cleaning up Launch
Configurations should help.

btw, how big is your workspace?

rookie...

Just .java files: 1,518 files taking up 5.5 MBytes
..metadata dir : 32,954 files taking up 326 MBytes

But then I have Preferences/ General/ Workspace/ Local History set for
365 days. Probably don't need that much of a back level, but it has
saved me on occasion, and it only takes once :-)

I have a few of them. One extreme case: the workspace is about 100M while
metadata is 93M! You are right, the monsters are in jdt.core, pde.core
and core.resources.

I just wish there were an easier way to clean them up instead of going
through different places like preferences etc.

Just curious, will RCP built based on Eclipse architecture encounter
similar problem?

Regards,

Feng

OMG, whole year back! you could get nice statistics from that.
CVS is supposed to do that. or better Git - where you can have a local
repository, so no need to pollute company's main repo.

keep in mind, it's for Eclipse performance. 100M for cache, with current
hard drives prices is hundrets times cheaper compared to CPU, that would
do the same thing with the same speed.

No, only if your RCP will include JDT or PDE and users will be creating
huge workspaces with big projects. Depends on your RCP.
