using subprojects in Free-Form Projects in NetBeans

I have a whole bunch of projects which are maintained by a colleague who works with eclipse.
The first attempt was to import the eclipse project into netbeans. But this was not successfull.
The eclipse project has one master project which encapsulates the others and there was
a hint about "The Eclipse project ... has a source root ( .... )".

So I used the free-form project with the existing ant file.

The problem were subprojects.

In the Master-project I referenced all including projects by name in
the original has an entry like which must be replaced with something like:


If you have everything inserted, the subprojects are opened and you can change to the
source with "Go To Type".

ATTENTION: When you change some project settings, the subprojects are lost!!!

I used NetBeans 6.7.1
