在一台机器上maven项目导入后报错：common.lang这个包找不到，但是另外一台机器没问题。运行maven dependency:tree 可以看到一台机器有这个依赖，这台机器没有。在项目执行mvn clean package时可以看到下面的警告：
The POM for org.springframework.cloud:spring-cloud-starter-netflix-hystrix:jar:2.1.1.RELEASE is invalid, transitive dependencies (if any) will not be available, enable debug logging for more details
[WARNING] The POM for org.springframework.cloud:spring-cloud-starter-netflix-hystrix-dashboard:jar:2.1.1.RELEASE is invalid, transitive dependencies (if any) will not be available, enable debug logging for more details

把对应的本地maven仓库jar包删除还是没用
mvn clean package -X 代开debug日志可以看到

把netty-bom这个目录删除，在重新执行mvn clean package，问题解决
