找不到 Kotlin 脚本 Gradle 的 kotlin-gradle-plugin

Question

构建失败，类路径错误：

thufir@dur:~/NetBeansProjects/kotlinShadowJar$ gradle clean

FAILURE: Build failed with an exception.

cat build.gradle.kts:

import com.github.jengelman.gradle.plugins.shadow.tasks.ShadowJar

buildscript {
    repositories {
        mavenCentral()
        gradleScriptKotlin()
    }
    dependencies {
        classpath(kotlinModule("gradle-plugin"))
        classpath("com.github.jengelman.gradle.plugins:shadow:1.2.3")
    }
}

apply {
    plugin("kotlin")
    plugin("com.github.johnrengelman.shadow")
}

repositories {
    mavenCentral()
}

val shadowJar: ShadowJar by tasks
shadowJar.apply {
    manifest.attributes.apply {
        put("Implementation-Title", "Gradle Jar File Example")
        put("Implementation-Version" version)
        put("Main-Class", "com.mkyong.DateUtils")
    }

    baseName = project.name + "-all"
}

构建文件是工作构建的direct copy。上下文从Kotlin script Gradle 开始。据我所知，脚本should be good。

请注意，我不使用 intelli-J，这完全来自带有 Kotlin 脚本 Gradle 的 CLI。

也许这是相当 simple 的东西，比如“插件”与“插件”...

查看错误日志，可以看到插件版本请求：

Searched in the following locations:
     file:/home/thufir/.gradle/caches/4.3.1/embedded-kotlin-repo-1.1.51-1/repo/org/jetbrains/kotlin/kotlin-gradle-plugin//kotlin-gradle-plugin-.pom
     file:/home/thufir/.gradle/caches/4.3.1/embedded-kotlin-repo-1.1.51-1/repo/org/jetbrains/kotlin/kotlin-gradle-plugin//kotlin-gradle-plugin-.jar
     https://repo1.maven.org/maven2/org/jetbrains/kotlin/kotlin-gradle-plugin//kotlin-gradle-plugin-.pom
     https://repo1.maven.org/maven2/org/jetbrains/kotlin/kotlin-gradle-plugin//kotlin-gradle-plugin-.jar
     https://repo.gradle.org/gradle/repo/org/jetbrains/kotlin/kotlin-gradle-plugin//kotlin-gradle-plugin-.pom
     https://repo.gradle.org/gradle/repo/org/jetbrains/kotlin/kotlin-gradle-plugin//kotlin-gradle-plugin-.jar

您可以看到每个插件请求都没有请求版本，因为他们正在寻找kotlin-gradle-plugin-.jar。

如果您look at the source，您还会看到kotlinModule 已被弃用。

我会推荐一些不同的更改来改进构建脚本：

1. 使用 Gradle 包装器 (./gradlew
2. 在升级 Gradle 版本之前为您的 kotlinModule 指定一个版本 - kotlinModule("gradle-plugin", "1.1.51")
3. 为插件使用plugins {} 块而不是buildscript
