我有两个 Gradle 子项目,它们基本上是哑 protobuf 容器。一个子项目需要从另一个导入定义,但我似乎无法弄清楚如何让 protobuf Gradle 插件正常工作(我对 Gradle 还很陌生)。
这是一个例子。
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)
plugins {
id "com.google.protobuf" version "0.8.12"
id "java"
}
configure (allprojects) {
apply plugin: 'java'
apply plugin: 'com.google.protobuf'
}
设置.gradle
rootProject.name = 'sample'
include 'main'
include 'dependency'
gradle.properties
group=sample
version=0.1.0
依赖/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'
}
依赖/src/main/proto/dependency.proto
syntax = "proto3";
package dependency;
option java_package = "dependency";
message DependencyRequest {
string foo = 1;
}
message DependencyResponse {
string bar = 1;
}
主/build.gradle
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')
}
主/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,我收到此错误:
$ ./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.
我阅读了插件的文档和这个答案,但我无法让它工作。知道为什么 protobuf 任务没有获取 dependency.proto 吗?
