----------------------------------
I think it may be possible to close this now, this seems to do the job:
http://mojo.codehaus.org/extra-enforcer-rules/banCircularDependencies.html
> Maven should fail the build or give a warning when there are cyclic
> dependencies
> --------------------------------------------------------------------------------
>
> Key: MNG-4999
> URL: https://jira.codehaus.org/browse/MNG-4999
> Project: Maven 2 & 3
> Issue Type: Bug
> Components: POM
> Affects Versions: 2.2.1, 3.0.2
> Environment: any
> Reporter: Phillip Hellewell
>
> Maven gives no warning or error when there are cyclic dependencies. It
> should give at least a warning, and have the ability to fail the build
> through an option.
> How to reproduce:
> 1. Make B that doesn't depend on anything. Deploy a snapshot of B.
> 2. Make A that depends on the snapshot of B . Deploy a snapshot of A.
> 3. Change B to depend on the snapshot of A. Now deploy a new snapshot of B
> (same version as in step 1).
> I would venture to say that the perc. of people who actually want to allow
> cycles is smaller than the percentage who want to catch it as an error.
