Description

My ivy.xml had a configuration which extended a configuration which did not exist.

<configurations>
<conf name="default" description="default minimum dependencies"/>
<conf name="compile" extends="default"
description="needed for compilation only"/>
<conf name="tests" extends="compile, runtime"
description="classes needed for running tests"/>
</configurations>

Notice tests extends runtime.

When resolving the dependencies, I received a NullPointerException.

After removing this problem with my ivy.xml, the resolve worked properly. Would probably want a more informative error here.

Thanks.
