模仿lombok工具，我的enumgen工具写完了。
公司的项目emax-rpcapi-list依赖了enumgen后，IDEARebuild Project时，或者maven package/install的时候，出现报错→Information:java: java.lang.AssertionError: Value of x -1
这个错误让我有点摸不着头脑。因为我自己的demo项目在依赖了enumgen是可以正常使用的。
仔细分析错误堆栈，注意到 visitClassDef、visitMethodDef 这些关键字。由于emax-rpcapi-list和我的demo项目同时也都依赖了lombok，直觉分析是enumgen与lombok产生冲突。我去修改我的注解处理器实现逻辑，去尝试解决，未能修复。中间排查过程相当曲折。最后在比对emax-rpcapi-list和我的demo工程时，才有了转机。
各种排查、各种试错，最后的解决办法有2个。
- 第一个是调整maven dependencies依赖顺序。我的要在lombok的前面先行依赖enumgen。
- 第二个是lombok版本兼容性。lombok版本1.18.20是有问题的，升级lombok的版本到1.18.24，就可以了。
此问题网上资料较少，在sun平台有提问，但是没有结果。
