Eclipse/maven: solution to cannot nest folders problem
I had the following problem with Eclipse 3.5 (Galileo) and m2Eclipse 0.9.8, but
from searching I believe that it occurs with other combinations as well.
Situation: I have a maven-ized project in subversion, and I want to check it
out into my Eclipse workspace. Method: bring up the subversion repositories
view, navigate to the repository folder with the project in it, right click,
select the “Check out as Maven Project …” context-menu option. All seems to
be OK – the project gets created, maven dependencies are resolved, etc, except
Problem symptom: Eclipse complains that Cannot nest 'rdfutil/src/test/java'
inside 'rdfutil/src'. To enable the nesting exclude 'test/' from 'rdfutil/src'
(your project name will obviously differ). And there’s a red ‘compilation
failed’ triangle in the problems list. Check the Java build path, all is fine.
Check the pom.xml, all is fine. What to do? Solution Right-click the
project node in the project explorer window to first close it, and then again
to delete the project, but without removing the project contents on disk.
Then, right-click in the project explorer window to “Import … > Existing
project into workspace …”. Navigate to the location of the project, import,
and it comes back without the nested file warning.
