可能是在请求 Jar 文件的 ClassPath，其中包含所需（导入的）库。如果您是从命令行运行，请尝试类似这样的操作：
java -cp .;"Jar 文件所在的完整路径\jarfile.jar" 您的运行类文件名

It may be asking for the ClassPath of the Jar File where the needed (imported) libraries are contained. If you are running from Command Line try something like this:
java -cp .;&quot;The full path where the Jar File is\jarfile.jar&quot; YourRunningClassFile
