Régis Décamps commented on MNG-3814:
------------------------------------
The problem occurs with any type of dependency. It can be a plugin dependency
or a dependency.
My project fails because
module-1.1 (uses plugin)-> plugin-1.0 (which depends on)-> module-1.0
> Reactor builds fail due to erroneous cycle in project sorting which does not
> consider versions
> ----------------------------------------------------------------------------------------------

> Key: MNG-3814
> URL: http://jira.codehaus.org/browse/MNG-3814
> Project: Maven 2
> Issue Type: Bug
> Components: Reactor and workspace
> Affects Versions: 2.0.9, 2.1.0-M1, 3.0-alpha-1
> Reporter: Benjamin Bentmann
>
> Just to officially track the reason why the parent POM {{maven-plugins}}
> currently excludes the maven-project-info-reports-plugin from the reactor:
> {noformat}
> [INFO] Scanning for projects...
> [INFO]
> ------------------------------------------------------------------------
> [ERROR] BUILD FAILURE
> [INFO]
> ------------------------------------------------------------------------
> [INFO] The projects in the reactor contain a cyclic reference:
> Edge between
> 'Vertex{label='org.apache.maven.plugins:maven-remote-resources-plugin'}'
> and
> 'Vertex{label='org.apache.maven.plugins:maven-project-info-reports-plugin'}'
> introduces to cycle in the graph
> org.apache.maven.plugins:maven-project-info-reports-plugin -->
> org.apache.maven.plugins:maven-remote-resources-plugin -->
> org.apache.maven.plugins:maven-project-info-reports-plugin
> {noformat}
> It appears the {{ProjectSorter}} does not take versions into account, i.e.
> there is no cycle in a multi-module scenario like this:
> {noformat}
> parent:1
> - plugin-a:2.0 which uses plugin-b:1.0
> - plugin-b:2.0 which uses plugin-a:1.0
> {noformat}
