--------------------------------------------------------------
Same problem occurs in maven 2.2 if you have 3 levels of poms:
* root (with dependency on module setup, modules=child1, ...)
* child1 (parent=root, modules=setup,...)
* setup (root=child1)

> Key: MNG-4184
> URL: http://jira.codehaus.org/browse/MNG-4184
> Project: Maven 2
> Issue Type: Bug
> Components: Dependencies
> Affects Versions: 2.1.0
> Reporter: Jörg Hohwiller
> Assignee: John Casey
> Fix For: 2.2.0
>
>
> In my project (https://m-m-m.svn.sourceforge.net/svnroot/m-m-m/trunk/)
> I am doing exactly what maven-checkstyle-plugin suggests as best practice for
> multi-module-builds:
> http://maven.apache.org/plugins/maven-checkstyle-plugin/examples/multi-module-config.html
> Howerver when I upgrade to maven 2.1 my build does not work anymore, while
> maven 2.0.10 works fine:
> [INFO] The projects in the reactor contain a cyclic reference: Edge between
> 'Vertex{label='net.sf.m-
> m-m:mmm-setup'}' and 'Vertex{label='net.sf.m-m-m:mmm-setup'}' introduces to
> cycle in the graph net.s
> f.m-m-m:mmm-setup --> net.sf.m-m-m:mmm-setup
> Indeed the module mmm-setup inherits from the toplevel-pom and therefore has
> a maven-checkstyle-plugin
> with a dependency on itself. However this worked with maven 2.0.x and if this
> is NOT going to be
> "fixed" in 2.1, you need to supply an acceptable workaround and update
> instructions such as
> the one linked above. Please also note that such config-moudles
> (net.sf.m-m-m:mmm-setup or
> com.example.whizbang:build-tools) should typically be available in IDE and
> other modules might
> depend on them so they have to be part of the reactor for eclipse:eclipse.
