Work around Gradle 6.0 deprecations.

[anuraaga]

• Groovy generates both getFoo and isFoo for boolean properties and Gradle doesn't like it anymore. So manually define getFoo to disable Groovy's generation

• All properties must be annotated, as a reminder for task authors I guess. Annotated the properties that can be Closure as @Internal

• Unit test now ensure we don't use deprecated stuff

Fixes #357

Thank you!

I need to find the time to look into #334 before releasing. The advice of removing the workaround of disabling canBeResolved sounds promising. It just needs to be feature flagged smartly first.

@ben-manes Do you see a chance for releasing a new version?

6.2 supposedly will break this plugin with a new feature, so waiting for that to release with a fix.
