[kepler-dev] Kepler source + eclipse

[David Welker]

Hi Michal,

Typically, it is not your responsibility to set _libraryDir. Looking at 
the "WARNING:" it looks like for some reason your $KEPLER directory is 
not being set correctly.  The KAR repository directory should be either 
<kepler.modules>/common/kar (for kepler-trunk) or 
<kepler.modules>/kepler-1.0-jar-tag/kar (for kepler-1.0).

My best guess is that somehow your eclipse workspace is somehow flawed. 
Normally, you should be able to simply type in "ant eclipse" to 
regenerate all the eclipse .project and .classpath files and then 
refresh all the projects and that should resolve things when this 
happens. If that doesn't work, you might consider emptying your 
workspace of all your projects and reimporting...

Also, I would definitely do an "svn update" in the build-area directory 
followed by an "ant update" command to ensure that all of your modules 
are downloaded correctly and up-to-date.

A tricky error that sometimes occurs is that a module you depend on is 
both not downloaded properly and there are no .svn files associated with 
it so it cannot update properly either. The build system assumes that if 
there is a folder with the same name as your module in <kepler.modules> 
that the module is already present. So, if you have an empty folder with 
the name of the module you need in <kepler.modules> maybe you are 
missing something.

Does the build work properly for you from the command-line? If not, that 
points to a problem with your eclipse workspace. You should consider 
starting fresh. If the command-line does work, that indicates you may be 
missing something in terms of not have retrieved all the modules you 
need properly.
