Build failed when adding Mockmp to an initial KMP project

[hantsy]

I tried to add Mockmp to my example project, which just include the initial codes from the KMP wizard, when run ./gradlew :composeApp:build -x test and got the following exceptions.

FAILURE: Build failed with an exception.

* What went wrong:
A problem was found with the configuration of task ':composeApp:mockmpExtractExpectKt' (type 'MocKMPExtractExpectKt').
  - Method 'execute' is private and annotated with @TaskAction.

    Reason: Annotations on private methods are ignored.

    Possible solutions:
      1. Make the method public.
      2. Annotate the public version of the method.

    For more information, please refer to https://docs.gradle.org/8.12/userguide/validation_problems.html#private_method_must_not_be_annotated in the Gradle documentation.
