在gradle 7.0.4版本中，A property without annotation isn't considered during up-to-date checking

[lcf687619]

    classpath 'com.android.tools.build:gradle:7.0.4'

Some problems were found with the configuration of task ':ImgCompressTask' (type 'ImgCompressTask').

• Type 'com.kingkingdu.ImgCompressTask' property 'compressedInfo' 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.
