Hi Ali,
I believe that an eclipseextension (ExtensionLocationMetadataRepository) can
only contain features/ and plugins/ directories. If you additionally have any
of p2 metadata files
({artifacts,compositeArtifacts,content,compositeContent}.{xml,jar}), this
becomes a p2 repository (StandardP2Repository). Finally, starting with Eclipse
4.2 an error is produced if one tries to load an eclipseextension directory
with one of the aforementioned files, unless there is a ".eclipseextension"
file which silences the error (see
https://bugs.eclipse.org/bugs/show_bug.cgi?id=348990). I don't know an answer
to your question, but hope this helps.
Kind regards,
Mikhail Kalkov

Please note that eclipseextension repo is automatically created with
below mentioned data even when you delete all the IUs from the eclipse-juno.
