Newest version of Android SDK has removed tools/ant/build.xml:

This causes "not found" error when compile jar.

Does this mean that Ant is not supported any more or can we just update our config and still use it?

It looks like Android has shifted towards encouraging use of Gradle much more since this project was created so maybe we should migrate to that instead.
