Description

Given the following two projects:

parent, released as organization POM
child, uses parent as its parent

parent pom is NOT in the local repository (i.e. new developer machine or build node of the CI)

settings.xml defines:

a) a global mirror for all repositories (http://local-nexus.srv/content/groups/public)

 <mirrors>
   <mirror>
      <id>Nexus</id>
      <name>Coporate Nexus</name>
      <url>http://local-nexus.srv/content/groups/public</url>
      <mirrorOf>*</mirrorOf>
    </mirror>
  </mirrors>

b) a profile "repos" including a snapshot repository and an active-profiles entry activating this profile

  <profiles>
    <profile>
      <id>repos</id>
      <repositories>
        <repository>
          <id>nexus-snapshots</id>
          <name>Projektserver Snapshots</name>
          <url>http://local-nexus.srv/content/repositories/snapshots</url>
		<releases>
			<enabled>false</enabled>
		</releases>
		<snapshots>
			<enabled>true</enabled>
			<checksumPolicy>fail</checksumPolicy>
			<updatePolicy>always</updatePolicy>		
		</snapshots>
        </repository>
      </repositories>
    </profile>
  </profiles>
  <activeProfiles>
    <activeProfile>repos</activeProfile>
  </activeProfiles>

This is a fairly standard setup for copporate development.

now, when trying to compile the project, the following error is thrown:

[INFO] Scanning for projects...
[ERROR] The build could not read 1 project -> [Help 1]
[ERROR]
[ERROR]   The project de.eucodos.bugs.maven:child:0.1-SNAPSHOT (X:\ACM\test\child\pom.xml) has 1 error

Without maven trying to download the parent from the corp-repo.

Sidenote: with Maven 2.x, this works without problems.

If an additional release-repository is included in profile "repos", everything works as expected:

  <profiles>
    <profile>
      <id>repos</id>
      <repositories>
	<repository>
          <id>nexus</id>
          <name>Projektserver</name>
          <url>http://msgs722i.msg.de:8080/nexus/content/groups/public</url>
		<releases>
			<enabled>true</enabled>
		</releases>
        </repository>
        <repository>
          <id>nexus-snapshots</id>
  ...
