Exception is:
org.gradle.internal.execution.WorkValidationException: Some problems were found with the configuration of task ':elasticsearch-spark-30:signSpark30scala213Publication' (type 'Sign').
  - In plugin 'org.gradle.plugins.signing.SigningPlugin_Decorated' type 'org.gradle.plugins.signing.Sign' property 'generatorsByKey./Users/rene/dev/elastic/elasticsearch-hadoop/spark/sql-30/build/classes/scala/spark30scala213.toSign' file '/Users/rene/dev/elastic/elasticsearch-hadoop/spark/sql-30/build/classes/scala/spark30scala213' is not a file.

    Reason: Expected an input to be a file but it was a directory.

    Possible solutions:
      1. Use a file as an input.
      2. Declare the input as a directory instead.

    For more information, please refer to <https://docs.gradle.org/8.14.2/userguide/validation_problems.html#unexpected_input_file_type> in the Gradle documentation.

The build cache configuration of the root build differs from the build cache configuration of the early evaluated ':projectA', ':projectB' included builds. It is recommended to keep them consistent, see here.

Such included builds will inherit the build cache configuration from the top level build, regardless of whether the included builds define build cache configuration themselves or not. The build cache configuration present for any included build is effectively ignored, in favour of the top level build’s configuration.

The request for this plugin could not be satisfied because the plugin is already on the classpath with a different version (1.8.22).
