I have been getting the following exception using the maven-jxr-plugin
<...several other exceptions omitted...>

This appears to be due to missing runtime dependencies on maven-reporting-impl.
uncommenting:
<!-- dependency>
<groupId>org.apache.maven.reporting</groupId>
<artifactId>maven-reporting-impl</artifactId>
<version>2.0-beta-1-SNAPSHOT</version>
</dependency -->
in the pom causes it to fail with another missing runtime dependency
on commons-collections, then another for avalon-logkit. Adding the
following to the pom successfully generates the report:
<dependency>
<groupId>commons-collections</groupId>
<artifactId>commons-collections</artifactId>
<version>3.1</version>
</dependency>
<dependency>
<groupId>avalon-logkit</groupId>
<artifactId>avalon-logkit</artifactId>
<version>2.1</version>
</dependency>
Are these dependencies omitted from the pom for a particular reason
(e.g. they should be transitively inherited), or is this an error
(e.g. plugin was written for an older version of m2)? Has anyone else
successfully used the jxr plugin with the latest and greatest m2?
I would be happy to submit a patch for the pom if this is actually an error...
