       Body:
Yes, it will.

But I think it's better then getting an exception. Anyway, the current behavior is not 
consistent, as javadoc:generate works. So we either change javadoc:jar to work too or 
change javadoc:generate to fail as well.

Another option would be enclosing the javadoc:install (and others) tags into a 
<util:available> tag. That way the jar won't be created and the goal won't fail. 

Anyway, it's just a matter of style (I, for instance, prefer a empty jar than nothing 
at all). So, whatever we decide, I can create a patch.

Description:
If your project doesn't have source files, javadoc:jar (and goals that depends on it, 
like javadoc:deploy) fails, even though javadoc itself suceeds.
You can reproduce this bug on the maven-plugins root:

$ maven javadoc
 __  __
|  \/  |__ _Apache__ ___
| |\/| / _` \ V / -_) ' \  ~ intelligent projects ~
|_|  |_\__,_|\_/\___|_||_|  v. 1.0-cpqd-1.0.0

It shouldn't be hard to fix this one - I will try a patch once I'm  back 
from my 'break' :-)
