Hi,
I have currently a problem with the maven-project-info-report-plugin, that
fails to create the project summary:

=========== %< ============
The problem is quite obvious, the question is, why is it suddenly triggered?
When I build an ear with the same set of plugins I also don't have a
src/main/java directory, but the project summary is created. Therefore it
seems somehow also related to the project itself. That one is build by a
custom plugin (more or less a very specialized assembly plugin generating a
ZIP file). The project is of custom type "qmb" and the plugin contains
following component.xml:
=========== %< ============
<component-set>
<components>
<component>
<role>org.apache.maven.lifecycle.mapping.LifecycleMapping</role>
<role-hint>qmb</role-hint>
<implementation>org.apache.maven.lifecycle.mapping.DefaultLifecycleMapping</implementation>

</configuration>
</component>
</components>
</component-set>
=========== %< ============
I tried to drop the language element in the component descriptor above and I
tried also a version with that element being empty. The plugin is built
against the artifacts of Maven 2.2.1.
The problem occurs running Maven 2.2.1 with site plugin 2.2 and report-info-
plugin 2.3. Downgrading PIR to 2.2 solves it.
For Maven 3 in combination with site 3.0-beta-3 and PIR 2.3, the project
summary generation works, but the javadoc plugin fails with a NPE because
target/site/apidocs dos not exists. Again a problem triggered by the Java
nature.
Apart from the regression I don't understand what triggers the Java handling
while the ear plugin does obviously not. Therefore I struggle to create a
test case here.
Any advice welcome,
Jörg
