Description dan carter CLA 2012-01-27 09:57:29 EST 
I have flat project structure, all projects exist at the same level in the directory in including the maven parent, but in this directory there is also a pom.xml which is a multimodule pom, to facilitate building the whole application with one command.

./myparentproj/pom.xml
./myliba/pom.xml
./mylibb/pom.xml
pom.xml

When i have this open as 4 projects, 

I have the multi-module pom.xml open as a project so that I can edit the pom.xml and commit atomically, but i add filters to the multimodule project to ignore the child projects, otherwise:
- 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.

But when i right click on a project and Maven ->  Update
Dependencies… or Maven ->  Update Project Configuration… it does not show any projects at all.

If I close the multimodule project, now the update project configuration dialog shows everything. (but now i can't do atomic commits)

If I keep the project open but remove the resource filters, it works too. (but now everything shows up twice in eclipse)


Attached is a workspace / maven project tree which demonstrates the problem.

Open the workspace testMvn, right click on test-libA, Maven -> Update Dependencies...  and the dialog shows no project to update.

Maybe I'm not following your steps in exactly the same way, but I have existing projects in my workspace as you've described, and adding resource filters doesn't prevent m2e from populating the dialog.

Did you forget to attach the example project?

Seems to be a project with the workspace, when i open on another machine it says the test-libA/.project is missing, although it is there!

Let me try again.

maven project tree

 mkdir newworkspace/
 cd newworkspace/
 tar xvfj ../test-aggregator.tbz


open newworkspace as an eclipse workspace
File -> Import -> Maven -> Existing Maven Projects
select test-aggregator -> (leave all 3 selected ) -> Finish

Right click test-libA -> Maven -> Update Project Configuration

no projects displayed.

Please try the attached project, now that i've finally attached successfully.

Also,

If you do have a similar setup that allows nested maven projects, where the filesystem represents the maven project hierarchy, and you do not suffer the duplicated resource issue, nor the issue i mention in this report, then i would be interested to know how you have your eclipse workspace setup.
