protoc custom plugin erroring out with Program not found or is not executable

阅读更多关于 protoc custom plugin erroring out with Program not found or is not executable

问题 I am trying to build a custom protoc plugin to generate custom output from .proto files. I literally copied java file containing CodeGenerator from protoc custom plugin as a starting point and renamed it. I also followed executable and created .sh file.

问题 The Official documentation about map type says: map<key_type, value_type> map_field = N; ...where the key_type can be any integral or string type (so, any scalar type except for floating point types and bytes). The value_type can be any type . I want to define a map<string, repeated string> field, but it seems illegal on my libprotoc 3.0.0 , which complains Expected ">" . So I wonder if there is any way to put repeated string into map. A Possible workaround could be: message ListOfString {

Instead, consider using composition: message Foo { Bar bar = 1; string id = 2; } However, that said, there is a trick you can use which is like inheritance -- but which is an ugly hack, so you should only use it with care. If you define your message types like: message Bar { string name = 1; }
