Description

This bug only happens if I have maven-javadoc-plugin enabled. If I comment it out site generation works. The POM is not specifying a particular version so I am not sure which one it is using.

These bugs seem to report the same problem against other plugins:
http://jira.codehaus.org/browse/MOJO-1118
http://jira.codehaus.org/browse/MOJO-1101

Based on the error message, I checked the repository after successfully building without JavaDoc and it shows these versions of commons-logging were used:
1.0
1.0.3
1.0.4
1.1

The only SNAPSHOT dependency is 2.1-SNAPSHOT of the maven-site-plugin (to get around site generation bugs). I am using the -U during building.

# mvn site
