David Hoffer commented on MEAR-212:
-----------------------------------
I was able to track down the change in my project that will cause this. My war
has a dependency on the following jar artifact. Since I am making a skinny war
in the ear, I have to also add this dependency in the ear. Once I do that it
causes the error. So its not possible to make a skinny war with this jar
dependency.
<dependency>
<groupId>org.apache.rampart</groupId>
<artifactId>rampart-core</artifactId>
<type>jar</type>
</dependency>
> Failed to initialize ear modules: Unknown artifact type[mar] for addressing

> Key: MEAR-212
> URL: https://jira.codehaus.org/browse/MEAR-212
> Project: Maven Ear Plugin
> Issue Type: Bug
> Affects Versions: 2.10
> Reporter: David Hoffer
>
> I'm trying to generate and ear file but I'm getting the following message:
> Failed to initialize ear modules: Unknown artifact type[mar] for addressing
> (full debug stack trace is below)
> However I don't have any mar artifacts in my dependencies. What I do have is
> a war that has 4 mar files added as resources and I'm making a ear with the
> skinny war feature.
> Why would the ear plugin give this error when it has no nothing to do with
> the mar resources in the war...or perhaps this error has nothing to do with
> those resources, not sure.
