Relative paths that start with a `.` now work for me. I noted one more case that should be handled and also left one minor comment.

build.gradle line 729:

This will exclude relative paths underneath the jfx directory you are in unless you explicitly add `./` before the directory. It's a rare case, but seems worth handling. Perhaps you can remove the `if` test entirely and always use `file(testSdkPath).absolutePath`?

build.gradle line 745:

> 743:     ext.TEST_SDK_DIR = "${rootProject.buildDir}"
> 744: }
> 745: println "TEST_SDK_PATH: " + TEST_SDK_DIR

Minor: Consider moving this down to the block where most other build properties like this are logged?
