老师，我执行bin目录下scanner的时候报了JDK版本错误的问题。是直接从8升到11吗？java.lang.UnsupportedClassVersionError: org/sonar/batch/bootstrapper/EnvironmentInformation has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0
