Emeric MARTINEAU commented on MJAVADOC-407:
-------------------------------------------
In fact, if you read documentation of javadoc tool, you don't need build output
dir. Javadoc tool works on source file.
Annotation can be found in source or classpath (see
http://www.oracle.com/technetwork/java/javase/documentation/index-137868.html#annotations).
But I have already see "home" maven plugin to be generate ".class" file
directly in build output dir (no source are generated).
I think in this case, issue raise up.
We are in tricky situation.
If we want to be backward compliant, you can use my patch and change default
value to false.

> ____________________________
> I now know that the reason is that the Maven Javadoc Plugin has changed from
> 2.9.1 to 2.10. and this is the cause of the problem.
> I can see this warning...
> [WARNING] 'build.plugins.plugin.version' for
> org.apache.maven.plugins:maven-javadoc-plugin is missing. [WARNING]
> 'build.plugins.plugin.version' for
> org.apache.maven.plugins:maven-deploy-plugin is missing.
> By setting the following in my pom....
> org.apache.maven.plugins maven-javadoc-plugin 2.9.1 attach-javadocs jar
> I can fix the version back to the last release.
