好像是因为，java -jar不允许对jar包进行修改，所以动态编译的class无法生成

[jhunters]

感觉好像是classpath的设置问题，能发一下你的测试工程吗？我复现一下原因

[lijunyong]

@jhunters 能给个联系方式吗？我已经测试过了，如果把所有依赖包都打到一个jar中，通过java -jar运行，无法动态编译生成class文件。如果把依赖的jar打到外面的文件夹是可以的，https://github.com/Baidu-ecom/Jprotobuf-rpc-socket/issues/27

通过java -jar运行，我也遇到这种问题，怎么把把依赖的jar打到外面的文件夹。

@dai2y 你试试
