在Gradle Kotlin项目中配置protobuf遇到麻烦

Question

我不知道我做错了什么。我遵循了许多指南，总是坚持在我的gradle kotlin build.gradle.kts文件中protobuf插件的protoc插件调用的分辨率。

这是我的整个文件:

import org.jetbrains.kotlin.gradle.tasks.KotlinCompile
buildscript {
    dependencies {
        classpath("com.google.protobuf:protobuf-gradle-plugin:0.8.14")
    }
}
plugins {
    id("com.google.protobuf") version "0.8.14"
    id("org.springframework.boot") version "2.4.1"
    id("io.spring.dependency-management") version "1.0.10.RELEASE"
    kotlin("jvm") version "1.4.21"
    kotlin("plugin.spring") version "1.4.21"
    kotlin("plugin.jpa") version "1.4.21"
}
group = "com.myapp"
version = "0.0.1-SNAPSHOT"
java.sourceCompatibility = JavaVersion.VERSION_15
repositories {
    mavenCentral()
}
dependencies {
    implementation("org.springframework.boot:spring-boot-starter-data-jpa")
    implementation("org.springframework.boot:spring-boot-starter-web")
    implementation("com.fasterxml.jackson.module:jackson-module-kotlin")
    implementation("org.jetbrains.kotlin:kotlin-reflect")
    implementation("org.jetbrains.kotlin:kotlin-stdlib-jdk8")
    // gRPC
    implementation( "io.grpc:grpc-protobuf:3.14.0")
    testImplementation("org.springframework.boot:spring-boot-starter-test")
    testImplementation("io.grpc:grpc-testing")
}
sourceSets {
    main {
        proto {
        }
    }
    test {
        proto {
        }
    }
}
protobuf {
    protoc {
        artifact("com.google.protobuf:protoc:0.8.14")
    }
}
tasks.withType<KotlinCompile> {
    kotlinOptions {
        freeCompilerArgs = listOf("-Xjsr305=strict")
        jvmTarget = "15"
    }
}
tasks.withType<Test> {
    useJUnitPlatform()
}

无论我做什么

protobuf {
    protoc { // <<<
        artifact("com.google.protobuf:protoc:0.8.14") // <<<
    }
}

此部分无法解析，导致以下错误:

我已经在Github上回答了这个问题。

您需要为协议导入com.google.protobuf.gradle.protoc。

artifact是协议定位器的属性(而不是函数)，所以应该是artifact = "com.google.protobuf:protoc:0.8.14"。
