Compatibility with Gradle 7.0 rc2

[Jeff11]

When running ./gradlew -Pandroid.enableJetifier=false canIDropJetifier I get the following output:

> Task :myapp:canIDropJetifier FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Some problems were found with the configuration of task ':myapp:canIDropJetifier' (type 'CanIDropJetifierTask').
  - Type 'CanIDropJetifierTask' property 'analyzeOnlyAndroidModules' is missing an input or output annotation.

    Reason: A property without annotation isn't considered during up-to-date checking.

This project hasn't been updated in two years. I jumped to https://github.com/dipien/bye-bye-jetifier on side project, worked no problem.

I worked around this by setting gradle.properties back to to distributionUrl=https\://services.gradle.org/distributions/gradle-6.7.1-all.zip

and in my build.gradle I had to go back to classpath 'com.android.tools.build:gradle:4.2.0'

and then it worked - and I can drop jetifier :-)
