如何使用maven插件合理地重命名包

Question

我的项目有以下模块：

• 客户端
• 其余

以上模块都依赖于com.google.protobuf，rest取决于client（rest模块使用protobuf jar client） 。

为了避免冲突，我使用com.google.protobuf插件将my.com.google.protobuf重命名为client模块中的shade。

问题是无法编译rest模块并报告以下错误：

error: incompatible types: my.com.google.protobuf.Descriptors.FileDescriptor cannot be converted to com.google.protobuf.Descriptors.FileDescriptor

一个更好的解决方法似乎是：在IntelliJ的项目视图中右键单击项目“客户端”-> pom.xml，选择“ Maven”->“忽略项目”。然后在顶级pom.xml上执行“ Maven”->“重新导入”。
