I tried putting the task code in the linked Gist into a build but the example simply fails to compile. The gist is missing how you use the extracted task type. After some minor changes unrelated to this issue your task type compiles. I was able to create and run it without any issue.

Please use the Gradle forums for support questions https://discuss.gradle.org/ and provide a build ready to reproduce if possible.
