Gradle protobuf任务未从依赖项中提取定义

我有两个Gradle子项目，它们基本上都是哑protobuf容器。一个子项目需要从另一个子项目导入定义，但我似乎不知道如何让protobuf-Gradle插件正常工作（我对Gradle还比较陌生）

这里有一个例子

目录布局：

build.gradle
settings.gradle
gradle.properties
dependency/
|
 - build.gradle
 - src/main/proto/dependency.proto
 main/
|
 - build.gradle
 - src/main/proto/main.proto

build.gradle（顶级）

格雷德尔酒店

rootProject.name = 'sample'

include 'main'
include 'dependency'

格拉德尔酒店

group=sample
version=0.1.0

依赖项/build.gradle

protobuf {
    protoc {
        artifact = "com.google.protobuf:protoc:3.11.0"
    }
}

dependencies {
    compile 'com.google.protobuf:protobuf-java:3.11.4'
    compile 'com.google.protobuf:protobuf-java-util:3.11.4'
}

protobuf {
    protoc {
        artifact = "com.google.protobuf:protoc:3.11.0"
    }
    plugins {
        grpc {
            artifact = 'io.grpc:protoc-gen-grpc-java:1.27.2'
        }
    }
    generateProtoTasks {
        all()*.plugins {
            grpc {}
        }
    }
}

dependencies {
    compile 'com.google.protobuf:protobuf-java:3.11.4'
    compile 'com.google.protobuf:protobuf-java-util:3.11.4'

    protobuf project(':dependency')
}

dependency/src/main/proto/dependency.proto

syntax = "proto3";

package dependency;

option java_package = "dependency";

message DependencyRequest {
        string foo = 1;
}

message DependencyResponse {
        string bar = 1;
}

main/build.gradle

protobuf {
    protoc {
        artifact = "com.google.protobuf:protoc:3.11.0"
    }
}

dependencies {
    compile 'com.google.protobuf:protobuf-java:3.11.4'
    compile 'com.google.protobuf:protobuf-java-util:3.11.4'
}

protobuf {
    protoc {
        artifact = "com.google.protobuf:protoc:3.11.0"
    }
    plugins {
        grpc {
            artifact = 'io.grpc:protoc-gen-grpc-java:1.27.2'
        }
    }
    generateProtoTasks {
        all()*.plugins {
            grpc {}
        }
    }
}

dependencies {
    compile 'com.google.protobuf:protobuf-java:3.11.4'
    compile 'com.google.protobuf:protobuf-java-util:3.11.4'

    protobuf project(':dependency')
}

main/src/main/proto/main.proto

syntax = "proto3";

package main;

option java_package = "main";

import "dependency/dependency.proto";

service MainService {

    rpc CallDependency(DependencyRequest) returns (DependencyResponse) {}

}

当我尝试构建时，会出现以下错误：

$ ./gradlew :main:compileJava
> Task :main:generateProto FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':main:generateProto'.
> protoc: stdout: . stderr: dependency/dependency.proto: File not found.
  main.proto:7:1: Import "dependency/dependency.proto" was not found or had errors.
  main.proto:11:24: "DependencyRequest" is not defined.
  main.proto:11:52: "DependencyResponse" is not defined.

我读了很多书，但一直没能让它发挥作用。知道protobuf任务为什么没有拾取dependency.proto吗？

显然protobuf文件设置正确，但包名不匹配导致main.proto无法找到dependency.proto。我可以通过删除protobuf定义中的包名来实现这一点

如果将来有人遇到此问题，请检查您的包名和导入以确保它们正确。
