Checkstyle uses commons-logging, which has classloader problems when initialized within a Maven plugin’s container. This results in the above message – if you run with ‘-e’, you’ll see something like the following: — Caused by: org.apache.commons.logging.LogConfigurationException: org.apache.commons.logging.LogConfigurationException: Class org.apache.commons.logging.impl.Jdk14Logger does not implement Log — buried deep in the stacktrace. The only workaround we currently have for this problem is to include another commons-logging Log implementation in the plugin itself.
