Re: 100% CPU in Eclipse - seems due to Subclipse with overlapping projects

I will have a go, but some end-of-financial-year deadlines
have caught 
up with me so I won't have a chance to try it for a few
weeks.  Some 
more information is that on the Subclipse mailing list
someone told me 
my problem is a known problem with the Subclipse plugin - it
does not 
handle overlapping source trees at present.  Subversive
apparently 
does.  So I think its a Subclipse bug, not an Eclipse bug
that I was 
facing.  This means probably nothing for Eclipse to do
here.

As a side note I am just looking for "the right
way" to do Maven 
development with Eclipse for large multi-module projects.  I
don't care 
too much which are the best tools.  We had been using
m2eclipse, but its 
been unreliable for us, and having it all in one project as
the source 
base has grown is no longer so effective.  Having
overlapping projects 
as in Eclipse 3.2 onwards is looking promising.  I am trying
one project 
per maven module (with its own .project file created by mvn

eclipse:eclipse) which also means each module gets its own
classpath 
(which is good - m2eclipse had a global classpath for
everything which 
causes problems if different WAR file modules want different
versions of 
jar files).  Having an parent overlapping project
corresponding to the 
root pom and all sub modules means I can use that root
project for svn 
branch/tag/switch stuff taking care of keeping all modules
in sync (we 
tag and branch at the project level, not the module level). 
I have no 
need to be able to compile from within the root project. I
do all final 
compiles and builds from the command line at present - I
just want 
compiles inside Eclipse during editing and debugging.  So
the Subversive 
+ mvn eclipse:eclipse + Eclipse >=3.2 is what I am trying
to get playing 
together nicely.

Thanks,
Alan

  I'd like to hear more about it. Can you please send your
concerns and 
expectations to m2eclipse mailing list?

  BTW, I added option to use separate modules in m2eclipse,
and new 
project import wizard will create separate projects for each
module.

  Eugene
