Empty src/main/java causes ejb plugin to fail
---------------------------------------------

                 Key: MEJB-50
                 URL: http://jira.codehaus.org/browse/MEJB-50
             Project: Maven 2.x EJB Plugin
          Issue Type: Bug
    Affects Versions: 2.2.1
         Environment: Apache Maven 2.2.1 (rdebian-1)
Java version: 1.6.0_22
Java home: /usr/lib/jvm/java-6-sun-1.6.0.22/jre
Default locale: en_GB, platform encoding: UTF-8
OS name: "linux" version: "2.6.32-24-generic" arch: "i386" Family: "unix" (Ubuntu 10.04)
            Reporter: Joe Littlejohn
            Priority: Minor


I have a created a simple project that includes a module with a packaging type of ejb. This module does not yet contain any Java classes. When I run {{mvn clean package}} I get the following error:

{{There was a problem creating the EJB archive: /home/jlittlej/workspace/todo/trunk/ToDo-Core/target/classes isn't a directory.}}

If the packaging type is jar, this error does not occur - a normal jar that doesn't contain any classes is built. If the packaging type is ejb, the build fails.

Full trace:
