~~MJAVADOC-145~~ If Javadoc is set to aggregate, the build fails inside a Maven plugin module

Description

« Hide

Using maven-javadoc-plugin Version 2.5 or 2.6 for a project of type <packaging>maven-plugin</packaging> leads to the following error message, even if the aggregation is not set:

Error extracting plugin descriptor: 'Goal: ... already exists in the plugin descriptor ...

Using maven-javadoc-plugin Version 2.2 solves this problem.

Could you please provide a test case? It seems that you have 2 identical goals...
Also, please provide debug files

Also, I tried with Doxia and Surefire and your profile seems to work.

@Vincent Siveton:
With the version 2.2 it works fine with the same profile and the same goals as mentioned
in the description.
Please have a look at http://jira.codehaus.org/browse/MJAVADOC-224.
I will provide more information asap.

jcrouvi, I (re) read the plugin code and my only idea is that the sourcepath list is not immutable in reactor mode [1].
Since I have no test case or failing project, could you please try this patch in your project?

It looks it failed on the grid.

I confirm it fails on my env too.
