如何用gradle脚本Kotlin构建文件构建一个可运行的ShadowJar？

你是说fatjar吗？ 如果是这样，您可以使用shadow gradle插件：

id 'com.github.johnrengelman.shadow' version '2.0.2'

如果您想使jar可执行，还需要将

Main类

添加到清单中（下面是带有包

test

的文件

application.kt

中的Main方法示例）：

使用此命令，您可以使用命令运行

jar

：

java-jar

下面我有一个简单的例子。文件

build.gradle

：

plugins {
    id 'com.github.johnrengelman.shadow' version '2.0.2'
    id "org.jetbrains.kotlin.jvm" version "1.2.21"
}

repositories {
    jcenter()
}

jar {
    manifest {
        attributes 'Main-Class': 'test.ApplicationKt'
    }
}

dependencies {
    compile("org.jetbrains.kotlin:kotlin-stdlib-jdk8")
    compile("org.simpleframework:simple-xml:2.5")
}

文件

test.Application.kt

：

package test

import org.simpleframework.xml.Element
import org.simpleframework.xml.ElementList
import org.simpleframework.xml.Root
import org.simpleframework.xml.core.Persister

private val testXml = """
<feed>
   <entry>
        <id> someid </id>
        <published> somedate </published>
   </entry>

   <entry>
        <id> someid2 </id>
        <published> somedate2 </published>
   </entry>
</feed>
""".trimIndent()

@Root(name = "feed", strict = false)
data class Feed(
        @field:ElementList(name = "entry", inline = true)
        var entriesList: List<Entry>? = null
)

@Root(name = "entry", strict = true)
data class Entry(
        @field:Element(name = "id")
        var id: String? = null,

        @field:Element(name = "published")
        var published: String? = null
)

fun main(args: Array<String>) {
    println(testXml)

    val serializer = Persister()

    val example = serializer.read(Feed::class.java, testXml)

    println(example)
}

谢谢，非常清楚。然而，我正在寻找一个

build.gradle.kts

文件，而不是上面提到的

build.gradle

。

    id 'com.github.johnrengelman.shadow' version '2.0.2'
