Ah ha!  You gave me an idea what the problem is.

I have a have 'multi-module' (not parent) pom in the parent directory

workspace/trunk/fitpjava/pom.xml
workspace/trunk/fitpjava/fitp-parent/pom.xml
workspace/trunk/fitpjava/libA/pom.xml
workspace/trunk/fitpjava/libB/pom.xml
etc

I have the multi-module pom.xml open as a project so that I can edit the pom.xml and commit atomically,  but this doesn't work well with eclipse/m2e
- all the files show up twice in the resource browser
- all the launch files show up twice in run/debug
- all the files show up twice in team synchronise and it's get very confused.

So on the parent directory project I setup a resource filter to include only pom.xml and .settings

If I close this project, now the update project configuration dialog shows everything.  So

If I keep the project open but remove the resource filters, it works too.

Seems to use eclipse I must move the multimodule pom into a child directory, except then all the maven and intelliJ users will complain.  Is there a better solution for this?

PS. I have tried 'hide folders that are physically nested' but this seem to only apply once at time of importing, if you import the multimodule and child projects together in one go.  So when projects are refactored or new ones added, I get the same issue with duplicate resources as the changed projects are not hidden in the parent.  Then I have to delete all 103 projects from my workspace and reimport them, which loses all my changeset assignments etc.

PPS. Running on linux with ext3 filesystem.

Thanks,
Dan.

m2e just reads all workspace projects and arranges them in a tree based on their filesystem location. This is the first time I hear about this problem, so I don't really know what might be going on. What platform and java version do you use? Do you store your project on some non-standard filesystem?

Also, if you are interested, have a look at the code that populates the tree [1], maybe you can spot something there.

Hello,
I have eclipse indigo with m2e working well except for one issue.
When I right click on a project and select Maven ->  Update
Dependencies… or Maven ->  Update Project Configuration… it pops up a
dialog that asks to select ‘Available Maven Codebases’.
The problem is the list is empty. Very occasionally it works, but most
of the time the list is empty.
How does m2e decide which projects to show? All my projects have the
little M decoration on the icon indicating they have the maven project
nature.
When the project configuration becomes out of sync I have to close and
re-open all the project with is very tedious… Thanks Dan.
