如何为 Kotlin (Gradle) 构建导入 ShadowJar 插件？

Question

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

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()
}

如上所述删除Shadow 的导入可提供干净的构建和运行。如何让 Kotlin 导入 Shadow 插件 JAR？

Gradle 本身使用 DSL，创建了 Shadow JAR 的罚款。

换个角度来看这个：

Kotlin 遇到 Gradle：gradle.build.kt with ShadowJar

带有工作构建文件。

像这样：

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

plugins {
    kotlin("jvm") version "1.5.21"
    id("com.github.johnrengelman.shadow") version "7.0.0"
}

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

repositories {
    mavenCentral()
}

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

tasks.withType<KotlinCompile> {
    kotlinOptions.jvmTarget = "11"
}

tasks.withType<ShadowJar> {
    archiveFileName.set("app.jar")
}
