gRPC java的编译

gRPC-java代码生成器

---

• gRPC-java的代码生成器编译需要先编译protobuf，否则会报c++源文件无法找到的错误
• 如果只是编译gRPC，而不打算编译代码生成器，可以使用下面的方法解决(详情请移步官方讨论组)：

If you are just going to build gRPC and try the examples, you can create the file "gradle.properties" under the project's root directory and add "skipCodegen=true" to it. This will skip the code generation.

grpc-java has a C++ code generation plugin for protoc. Since many Java developers don't have C compilers installed and don't need to modify the codegen, the build can skip it. To skip, create the file <project-root>/gradle.properties and add skipCodegen=true
