java.lang.NullPointerException during ANT build process handling Ordered Dependencies
===

We have an `ANT` build process that builds all of our android projects at once. It is completely based on the build process encouraged by android.

We switched to ADT20 and the build process now fails when we are building a `release`. The android build process fails when trying to handle "Ordered Dependencies" during the `-build-setup`.

We sign our `release` applications with an `ant.properties` file that contains the `key.store`, `key.alias`, `key.store.password` and `key.alias.password`. 

It fails with the following error:

    C:\PATH\android-sdks\tools\ant\build.xml:546: java.lang.NullPointerException

That is all it says without the `-debug` flag.

With the `-debug` flag i am getting this:

    C:\PATH\android-sdks\tools\ant\build.xml:546: java.lang.NullPointerException
