Task :publishGuide FAILED

FAILURE: Build failed with an exception.

• What went wrong:
  A problem was found with the configuration of task ':publishGuide' (type 'PublishGuide').

  • Type 'grails.doc.gradle.PublishGuide' property 'resourcesDir' specifies directory '/home/runner/work/grails-cache/grails-cache/build/resources/grails-common-build-master/src/main/resources' which doesn't exist.

    Reason: An input file was expected to be present but it doesn't exist.

    Possible solutions:

    1. Make sure the directory exists before the task is called.
    2. Make sure that the task which produces the directory is declared as an input.
