We put that message in to reduce confusion; seems ok to me

That wont work because of this:
 - The task is not an Ant core or optional task
 and needs to be declared using <taskdef>.

you cannot redeclare stuff that is already declared; classpath issues:.

This was a brave effort, but it aint going to work.

What was wrong with following this advice :

> - The task needs an external JAR file to execute
> and this is not found at the right place in the classpath.
> Fix: check the documentation for dependencies.
