build errors about CleanAndroidOpenCVBuildFolderTask missing annotations

[brianm-sra]

I followed the steps in the README to update my project build.gradle and app build.gradle

When I build on Ubuntu Linux with

./gradlew clean assembleDebug

I get the following errors about missing annotations in CleanAndroidOpenCVBuildFolderTask:

FAILURE: Build failed with an exception.

* What went wrong:
Some problems were found with the configuration of task ':passthrough:cleanAndroidOpenCVBuildFolder' (type 'CleanAndroidOpenCVBuildFolderTask').
  - In plugin 'com.ahasbini.android-opencv-gradle-plugin' type 'com.ahasbini.tools.androidopencv.task.CleanAndroidOpenCVBuildFolderTask' property 'description' is missing an input or output annotation.
    
    Reason: A property without annotation isn't considered during up-to-date checking.
