Slawomir Jaranowski commented on MENFORCER-378:
-----------------------------------------------
Ok, I see that should be not issue about only optional but optional with
missing artifacts.
We can add a IT test for it.
> requireReleaseDeps does not support optional dependencies or runtime scope

> With using the <requireReleaseDeps> the enforcer throws a RuntimeException
> due to the following error:

> This file is an optional dependency and the POM is sometimes not available. I
> have given the optional parameter in the POM

> <type>selector</type>
> <scope>runtime</scope>
> <optional>true</optional>

> I report this as a bug, since the <optional> parameter is long supported in
> maven.
> In my opinion "AbstractBanDependencies.getDependenciesToCheck" line 139
> should have a 'if present and if optional' check. If so, no RuntimeException
> should be thrown. I'll leave it to you if <scope>runtime should also be
> excused from the RuntimeException.
> I have no other option (no workaround) than to skip the Enforcer for this
> project.
