AppDistribution Gradle plugin with Gradle 7

Question

I am using Android Gradle Plugin version 7.0.0-alpha14 and Gradle version 7.0 and when I try to upload the app to app distribution through the Gradle plugin version 2.1.0 it fails on a task app:appDistributionUploadDebug with an error

> Task :app:appDistributionUploadDebug FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Some problems were found with the configuration of task ':app:appDistributionUploadDebug' (type 'UploadDistributionTask').
  - Type 'UploadDistributionTask' property 'COMMAND_LINE_PREFIX' is missing an input or output annotation.
    
    Reason: A property without annotation isn't considered during up-to-date checking.
    
    Possible solutions:
      1. Add an input or output annotation.
      2. Mark it as @Internal.
    
    Please refer to https://docs.gradle.org/7.0/userguide/validation_problems.html#missing_annotation for more details about this problem.

I suppose the plugin is not compatible with Gradle 7 but is it a known issue and is there some workaround? Thanks
