I'm following the instructions at
http://help.eclipse.org/ganymede/topic/org.eclipse.pde.doc.u ser/tasks/pde_product_build.htm
to build an set up an automated build for an RCP application. The build
doesn't get far, but terminates with a NullPointerException:

When run with -verbose, this is where the exception appears to be thrown:

Any idea what could be going wrong here?

What's your root build.properties look like?

Also, I find this tutorial pretty good:

This is probably a problem with the "baseLocation" property.
Make sure the directory it points to exists. If you don't have a
baseLocation, either don't define the property, or leave it blank.

That's it!

Bad:

baseLocation="C:/Program Files/Eclipse"

Good:

baseLocation=C:/Program Files/Eclipse
