Is your Checkstyle version in your settings set to 8.1?

I looked through the release notes for Checkstyle and found that version 8.2 removed the FileContentsHolder module, which would explain the failure to instantiate the module and thereby, the exception thrown since Gradle uses version 8.1.

I changed my checkstyle version to 8.24 and received the same error that you received as well.

Kudos for the taking extra effort to look into the problem @shaoyi1997 👍
