Subject eclipse and maven working together...
Date Thu, 14 Mar 2013 03:33:01 GMT
With the included checkins, I made some changes to help developers with better productivity.

With maven not supporting incremental build, most people are building with mvn clean install.
 After doing that, you probably see eclipse start rebuilding the workspace and eclipse is
slow when that happens.  I thought that was strange and figured it was because maven and eclipse
are sharing the same target directories.  A quick search on that turns up that this is a common
problem already described on m2e's faq [1].

So with this commit, I did the following things.

I changed the outputDirectory of the build to be based on a config variable.  The default
is the normal target directory.  However with the eclipse profile, it gets set to target-eclipse.
 What this means is that

- When compiling outside of eclipse, it uses target to contain the generated files.
- When compiling inside eclipse, it depends on the active profile for the project.  If it
contains eclipse, then it uses target-eclipse.  If it doesn't contain anything, then it uses
target like before.

Here comes the hard part, in order to make this work, you need to run a script that I checked
in.  Run it with bash.  Works in Cygwin for me.

Quite eclipse.

>From the top directory, run 


This will set all of the projects to have profile eclipse.  From then on, your eclipse won't
be recompiling the workspace every time you run mvn clean install in a terminal.  It also
avoids a race condition between mvn and eclipse in building the class files.
