Error building POM (may not be this project's POM).

[java javae]

  
Hi, 

I have a problem with compiling my projects under continuum using the top
parent of my projects. I remove the --non-recursive flag on the build
directive of my top projects.

The pom.xml of the modules projects looks like this:
...
    <modules>
        <module>../Project_A</module>
        <module>../Project_B/module>
        <module>../Project_C</module>
    </modules>
...

when I try to build from the top parent of my project pom.xml I get this error:

[INFO] Scanning for projects...
[INFO] ------------------------------------------------------------------------
[ERROR] FATAL ERROR
[INFO] ------------------------------------------------------------------------
[INFO] Error building POM (may not be this project's POM).
...

Project ID: unknown

Reason: Could not find the model file 
'C:\apache-continuum-1.2.3\data\working-directory\Project_A'. for project 
unknown

Any idea why I get this error? 

Thanks.
