Gradle Plugin seems to be not working.

[Pezhin]

I was trying on testing https://github.com/robolectric/robolectric and following steps in README to use the gradle plugin. After modifying build.gradle, I ran ./gradlew nondexTest on OSX, and it prints

Task 'nondexTest' not found in root project 'parent'. Some candidates are: 'nondexHelp'.

However, after I ran nondexHelp, it does print out nodexTest

This plugin has 2 tasks:

nondexTest
    Run tests with nondex and find out the non-deterministic issue

nondexHelp
    Print this help message

Not sure what is happening and I tried another random gradle project: https://github.com/Meituan-Dianping/AppInit. Same things happened.

Task 'nondexTest' not found in root project 'AppInit'. Some candidates are: 'nondexHelp'.
