Description

This simple POM

<project>
  <modelVersion>4.0.0</modelVersion>

  <groupId>${groupId}</groupId>
  <artifactId>test</artifactId>
  <version>0.1</version>
  <packaging>jar</packaging>

  <distributionManagement>
    <repository>
      <id>maven-core-it</id>
      <url>file:///${basedir}/repo</url>
    </repository>
  </distributionManagement>
</project>

causes the following model errors:

[ERROR]     Resolving expression: '${groupId}': Detected the following recursive expression cycle: [groupId] -> [Help 2]

[ERROR]     'groupId' with value '${groupId}' does not match a valid id pattern. @ line 25, column 12

Note the excessive repetition of the groupId related cycle although this expression actually appears only once in the POM.
