Subject RE: Setting up a better eclipse environment....
Date Wed, 06 Mar 2013 01:06:35 GMT
Another tip I have is to create one source repo and workspace for one major branch.  We've
been changing our environment a lot and it really messes with the whole git checkout <branch>
and then have eclipse reconfigure automatically.  It has the added benefit of working on multiple
branches at the same time simply by opening multiple eclipses.  

Just don't create workspaces in the directory you store your source.  This used to be okay
for me back in the ant days but since the switch to maven, eclipse has had really weird problems
with that.  Once I stored the workspace outside of the source directory, everything works
