./gradlew build fails in multi-project build

[JacobJBublitz]

When the build task is ran from a multi-project build it fails with a NullPointerException. Both projects use the GradleRIO plugin and the root project depends on the sub-project.

$ ./gradlew build
> Task :extractTestJNI FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':extractTestJNI'.
> java.lang.NullPointerException (no error message)

An example project can be found here: https://github.com/Kaboomboom3/GradleRIO-Build-Test

This is already fixed in #289 and is pending publish
