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

_   _,_ _/___ _ _ 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'

Hi Arnaud,

Thanks for opening this issue (I couldn't, as Jira was bug).

Anyway, the fix is pretty simple: it's just a matter of callign mkdir before the <j:if> statement:

Before it was:
<goal name="maven-javadoc-plugin:report"
description="Generate API documentation" prereqs="xdoc:init">

<javadoc:init/>
<j:if test="${internal.javadoc.needed}">
<ant:mkdir dir="${maven.javadoc.destdir}"/>

Now it should be:

<ant:mkdir dir="${maven.javadoc.destdir}"/>
<j:if test="${internal.javadoc.needed}">

I'll provide a patch...

Felipe

If we do this, won't we create an empty jar ?

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.

Temporarly I commited the fix with the mkdir before the test.
I'll do somethink better with util:available to definitively close this issue.
