Nate Good commented on MNG-1943:
--------------------------------
I have just experienced this issue in a more critical use case. Here are the
details. Please let me know if you need more information.
${buildVersion} is a property defined in a profile in settings.xml and is used
in all poms.
<parent>
<artifactId>bar</artifactId>
<groupId>foo.bar</groupId>
<version>${buildVersion}</version>
</parent>
It seems that the problem presents itself when a project depends on an artifact
that has a parent with a non-literal value; and the parent pom is not located
on the filesystem.
Example:
pom.xml - This is the master pom that all others inherit from
Project A
pom.xml - Inherits from master pom
A.x
pom.xml - inherits from ProjectA/pom.xml
Project B
pom.xml - depends on A.x
if you run maven on ProjectB and A.x is located in a remote repository it will
fail because ${buildVersion} in A.x/pom.xml will not be interpolated before it
is used to lookup the pom.
Here is the resulting stack trace (from version 2.0.9):
Caused by: org.apache.maven.project.ProjectBuildingException:
Cannot find parent: foo.bar:xyz-pom for project:
foo.bar:prompting-client:jar:${buildVersion} for project
foo.bar:zyx-client:jar:${buildVersion}

org.apache.maven.project.artifact.MavenMetadataSource.retrieve(MavenMetadataSource.java:106)
Is this scheduled to be fixed in the next maven release?
