------------------------

             Summary: Parent POMs not resolved in multi-module project
                 Key: MNG-5682
                 URL: https://jira.codehaus.org/browse/MNG-5682
             Project: Maven
          Issue Type: Bug
          Components: Bootstrap & Build
    Affects Versions: 3.2.3, 3.1.1, 3.0.4
         Environment: Apache Maven 3.2.3 (33f8c3e1027c3ddde99d3cdebad2656a31e8fdf4; 2014-08-11T22:58:10+02:00)
Java version: 1.7.0_67, vendor: Oracle Corporation
Default locale: en_US, platform encoding: Cp1250
OS name: "windows 7", version: "6.1", arch: "x86", family: "windows"
            Reporter: Kek
            Priority: Critical
         Attachments: test-project.zip

I have multi-module project - I attach the similar simple project structure to this issue, to simulate the problem =>  !test-project.zip!.

The structure is:
{noformat}
A    - aggregating project, parent for "parent"
 |_parent  - parent for B and C
 |_B
 |_C
{noformat}

In reality we have more parents under A for diferent types of A-submodules, but now it does not matter.

When we run build under maven 2.2.1  - everything is OK, the reactor sorts the projects like  A, PARENT, B,C and build success.

When we run the same build under maven 3.x  (3.0.4, 3.1.1, 3.2.3 was tested), the build fails with following errors:


a>mvn clean

There is no explicit "relativePath" set in project POMs.
