Description

If we have a submodule project producing a war archive, javadoc:aggregate fails with the following message:

[WARNING] Only outputDirectories and jars are accepted on the path
 [ERROR] Error while creating javadoc report: Only outputDirectories and jars are accepted on the path
 java.lang.IllegalArgumentException: Only outputDirectories and jars are accepted on the path
     at org.codehaus.plexus.languages.java.jpms.LocationManager.resolvePath (LocationManager.java:333)

     at org.apache.maven.plugins.javadoc.AbstractJavadocMojo.addJavadocOptions (AbstractJavadocMojo.java:5001)

After some investigations it seems it tries to pass the war package to LocationManager.resolvePath.

I've added a quickstart project to reproduce the problem. Just run:

mvn package javadoc:aggregate
