Hi
As I mentioned in the vote thread I had serious problems with the
Javadoc Plugin during the release. After having done some more testing
I'd like to present my findings.
1. The Javadoc Plugin has class loading interference when run from
Maven 2.2.1. Somehow the class path is modified and broken during a
build. In my case this leads to an exception during Javadoc generation.
See stack trace below. This meant that I could not publish the site
using Maven 2.2.1. Using Maven 3.0.3 worked.
Upgrading to the latest 2.8-SNAPSHOT of the plugin does not solve this
issue. I don't know whether the bug is in Maven or the Javadoc Plugin,
but I'm guessing the latter. Looking through the current unresolved
issues fr Javadoc Plugin I'm unable to find a matching issue.
2. Version 2.7 of the Javadoc Plugin takes exponentionally longer time
to run based on the number of modules in a multi module build. Doing
'mvn site:stage-deploy -Preporting' for Doxia took 89 minutes on my new
4-core, 8GB, SSD-equipped machine. No, I'm not kidding - 89 minutes!
Doxia has 19 modules. For each module the Javadocs (and test Javadocs)
for *all* the other modules are created. You do the math.
The good thing is that this seems to have been fixed in 2.8-SNAPSHOT,
probably in MJAVADOC-284. We need to release 2.8 and update maven-parent
to that ASAP.
Stacktrace when running 'mvn site -Preporting' on the current trunk of
Doxia Sitetools. You should be able to use the revision prior to the
release (r1096869) to see this, if you haven't yet downloaded the staged
1.2-version of Doxia. A similar stacktrace occurs for Doxia, but the
build time for that project is considerably longer.
