The error occurs because of me adding jar library files to MODULEPATH instead of CLASSPATH.发生错误是因为我将 jar 库文件添加到 MODULEPATH 而不是 CLASSPATH。 You have to add jar files to your CLASSPATH.您必须将 jar 文件添加到您的 CLASSPATH。 If you already add jar files to MODLEPATH you have to remove from there and add jar files to CLASSPATH as on: Error occurred during initialization of boot layer如果您已经将 jar 文件添加到 MODLEPATH 中，则必须从那里删除并将 jar 文件添加到 CLASSPATH 中： 启动层初始化期间发生错误
