Fail on project without any classes

I have some maven projects that don't have any classes in them (one is an ear project, the other a ressource jar).

Findbugs fails on them returning a NoClassesFoundToAnalyzeException. I'm not sure if the plugin can fix this or if it's a findbugs issue. And yes, the solution below is probably the more efficient way to handle this. I think a more meaningful error could be returned by the plugin though (a catch around FindBugsMojo line 740)

The workaround add the code below to these projects poms:

<plugin>
        <groupId>org.codehaus.mojo</groupId>
        <artifactId>findbugs-maven-plugin</artifactId>
        <version>2.0.1.3.2</version>
        <configuration>
          <skip>true</skip>
        </configuration>
      </plugin>
