Hi Karol,

>/home/kka34/runtime-EclipseApplication/TestProject overlaps the
location of another project: 'TestProject'.
> Any ideas on what could be wrong?

The resource APIs are a bit tricky here.  When you create a new project,
you should specify the project location as null if you want it to go in
the default location -- i.e., <workspace root> / <project name>.  

Only use IProjectDescription#setLocation[URI]() to set a non-null
location if it *won't* live in that default location, otherwise you'll
get the "overlapping location" error.

My appologies, but GMail sent this email before I was finished. Below is
the entire email.

Hi,

I am trying to programitically create an new managed make project and
after poking around the CDT New Project Wizards I came up with the code
at the end of the post. The problem is that the
createCDTProject() function complains about a location overlap with an
existing project:
/home/kka34/runtime-EclipseApplication/TestProject overlaps the location
of another project: 'TestProject'.
I am not sure why I am getting this error, because I have not even
touched the repoLocation variables before using it in this function.
Any ideas on what could be wrong?

Cheers,
Karol Krizka
