如何导入Kotlin(Gradle)版本的ShadowJar插件? [英] how to import the ShadowJar plugin for Kotlin (Gradle) builds?

问题描述

构建失败:

thufir@dur:~/NetBeansProjects/kotlin_dsl$ 
thufir@dur:~/NetBeansProjects/kotlin_dsl$ gradle clean run 

> Configure project : 
e: /home/thufir/NetBeansProjects/kotlin_dsl/build.gradle.kts:4:12: Unresolved reference: github


FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring root project 'kotlin_dsl'.
> Could not open cache directory 74ykawxta6db3b2bfk9grjikp (/home/thufir/.gradle/caches/4.3.1/gradle-kotlin-dsl/74ykawxta6db3b2bfk9grjikp).
   > Internal error: unable to compile script, see log for details

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

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

BUILD FAILED in 1s
thufir@dur:~/NetBeansProjects/kotlin_dsl$ 

有问题的导入语句:

thufir@dur:~/NetBeansProjects/kotlin_dsl$ 
thufir@dur:~/NetBeansProjects/kotlin_dsl$ cat build.gradle.kts 

import org.gradle.api.JavaVersion
import org.gradle.kotlin.dsl.*
import com.github.jengelman.gradle.plugins.shadow.tasks.ShadowJar


plugins {
    application
    kotlin("jvm") version "1.1.51"
}

application {
    mainClassName = "samples.HelloWorldKt"
}

dependencies {
    compile(kotlin("stdlib"))
}

repositories {
    jcenter()
}


thufir@dur:~/NetBeansProjects/kotlin_dsl$ 

删除如所描述的对Shadow的导入，可以进行干净的构建并运行. Shadow插件JAR如何使Kotlin可以导入?

removing the import for Shadow as described gives a clean build and run. How is the Shadow plugin JAR made available for Kotlin to import?

Gradle本身使用DSL可以创建Shadow JAR.

从另一个角度来看:

科特林遇到Gradle:与ShadowJar一起gradle.build.kt

带有有效的构建文件.

推荐答案

像这样:

import org.jetbrains.kotlin.gradle.tasks.KotlinCompile
import com.github.jengelman.gradle.plugins.shadow.tasks.ShadowJar

plugins {
    kotlin("jvm") version "1.2.51"
    id("com.github.johnrengelman.shadow") version "2.0.4"
}

group = "xxx.yyy"
version = "1.0-SNAPSHOT"

repositories {
    mavenCentral()
}

dependencies {
    implementation(kotlin("stdlib-jdk8"))
}

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

tasks.withType<ShadowJar> {
    baseName = "app"
    classifier = ""
    version = ""
}
