Ivy plugin throws a NullPointerException if you leave the targets field blank. It should just default to using whatever the default target is in the build.xml file.

Reported by Cristian Vulpe on the users list.

Hello..

I am beginning to set up Hudson with Ivy for our build structure.
I am using a placeholder build.xml and ivy.xml. When I do a build,
I get the exception below.
Could you please take a look and let me know what's up?

Thank you..
