Protobuf配置Intellij Idea Plugin Gradle-kotlin-dsl kotlin

Question

嘿，我想在 intellij idea 插件中设置 protobuf 作为其他 protobuf 服务器（用 golang 编写）的客户端。这将是我对 grpc 的第一个 java 方法。我尝试使用 kotlin classess 生成器，但我比使用这种方法更不成功。

我的目标是：最佳情况：插件将允许将 proto 编译为 kt 文件非常好的案例场景：插件将输出 java 个文件到 src/main/proto

现有代码结构：

└───src
    ├───main
    │   ├───kotlin
    │   │   └───pl
    │   │       └───dominikw
    │   │           ├───configuration
    │   │           ├───model
    │   │           ├───service
    │   │           │   └───impl
    │   │           └───ui
    │   ├───proto
    │   └───resources
    │       ├───icons
    │       └───META-INF
    └───test
        ├───kotlin
        └───resources

和Gradle kotlin dsl 文件：

import com.google.protobuf.gradle.*
import org.jetbrains.kotlin.gradle.tasks.KotlinCompile

group = "pl.dominikw"
version = "0.1.1"
val protobufVersion = "3.9.1"

    main {
        java.srcDir("src/main/kotlin")
        resources.srcDir("src/main/resources")
        proto.srcDir("src/main/proto")
    }
}

intellij {

tasks.getByName<org.jetbrains.intellij.tasks.PatchPluginXmlTask>("patchPluginXml") {
    changeNotes(
        """

    )
}

configure<org.jetbrains.intellij.IntelliJPluginExtension> {
    version = "2019.2"
    updateSinceUntilBuild = true
    pluginName = "Windchill-Plugin"

tasks.withType<KotlinCompile> {
    kotlinOptions.jvmTarget = "1.8"
}

protobuf {
    protoc {
        artifact = "com.google.protobuf:protoc:$protobufVersion"
    }
    plugins {
        id("grpc") {
            artifact = "io.grpc:protoc-gen-grpc-java:1.15.1"
        }
    }
    generateProtoTasks {
        ofSourceSet("main").forEach {
            it.plugins {
                id("grpc")
            }
        }
    }
}

错误代码如下：

7:17:20 PM: Executing task 'generateProto'...

> Task :extractIncludeProto UP-TO-DATE
> Task :extractProto UP-TO-DATE
> Task :generateProto FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':generateProto'.
> protoc: stdout: . stderr: C:\Users\XXX\IdeaProjects\Windchill-Intellij-Plugin\build\extracted-protos\main\service.proto: Input is shadowed in the --proto_path by "C:/Users/XXX/IdeaProjects/Windchill-Intellij-Plugin/src/main/proto/service.proto".  Either use the latter file as your input or reorder the --proto_path so that the former file's location comes first.


* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Get more help at https://help.gradle.org

Answer 1

您的错误信息是：

  ...Input is shadowed in the --proto_path by "C:/Users/XXX/IdeaProjects/Windchill-Intellij-Plugin/src/main/proto/service.proto".

您的 proto 文件夹中的 .proto 文件有一些无效的定义。
