NullPointer in DependenciesNode if using a compileProject dependency

[deveth0]

Hi,

I've a project setup with a android application using a compileProject dependency. If the dependency has never been compiled (or the build folder been deleted), opening the Dependencies Node in Netbeans causes a NPE (see below).

I think the reason is a missing null-check in DependenciesNode:87.

Cheers
