如何使用gradle将配置文件或任何其他资源添加到我的jar中？

我的项目结构:

src/main/java/com/perseus/.. --- Java包(源文件)

src/main/java/config/*.xml --- Spring配置文件

预期的罐子结构:

com/perseus/.. --- Java包(类文件)

config/*.xml --- Spring配置文件

正如标题所述,我想知道如何修改它gradle.build.kts以便创建一个独特jar的所有依赖项(包括kotlin lib)的任务.

我在Groovy中找到了这个示例:

//create a single Jar with all dependencies
task fatJar(type: Jar) {
    manifest {
        attributes 'Implementation-Title': 'Gradle Jar File Example',
            'Implementation-Version': version,
            'Main-Class': 'com.mkyong.DateUtils'
    }
    baseName = project.name + '-all'
    from { configurations.compile.collect { it.isDirectory() ? it : zipTree(it) } }
    with jar
}

但我不知道如何在kotlin中写出来,除了:

task("fatJar") {

}

我正在尝试使用kotlin和gradle,但我无法使用Intellij Idea 15成功创建项目.

我已经创建了有两个模块简单的项目hello-java和hello-kotlin.

hello-java 是普通的java项目,它正在编译和运行完美.

hello-kotlin是简单的kotin模块,只有一个*.kt文件和build.gradle文件.
以下是来源:

的build.gradle

group 'pl.fzymek.kotlin'
version '1.0-SNAPSHOT'

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:0.10.4"
    }
}

apply plugin: 'kotlin'
apply plugin: 'application'

mainClassName = 'HelloKotlinKt'

repositories {
    mavenCentral()
}

jar {
    manifest {
        attributes 'Main-Class': mainClassName
    }
}

dependencies {
    compile "org.jetbrains.kotlin:kotlin-stdlib:0.10.4"
}

HelloKotlin.kt

fun main(args: Array<String>) {
    println("Hello, Kotlin!")
}

主模块settings.gradle

include 'hello-java'
include 'hello-kotlin'

运行时gradlew clean build所有项目都编译成功,但运行时出现java -jar hello-kotlin-1.0-SNAPSHOT.jar …

最简单的Kotlin hello world for gradle script Kotlin:

thufir@dur:~/github/gradleScriptKotlin$ 
thufir@dur:~/github/gradleScriptKotlin$ gradle clean shadowJar;java -jar build/libs/gradleScriptKotlin.jar 

> Task :compileKotlin 
Using Kotlin incremental compilation

> Task :shadowJar 
A problem was found with the configuration of task ':shadowJar'. Registering invalid inputs and outputs via TaskInputs and TaskOutputs methods has been deprecated and is scheduled to be removed in Gradle 5.0.
 - No value has been specified for property 'mainClassName'.
The SimpleWorkResult type has been deprecated and is scheduled to be removed in Gradle …

我尝试使用 Intellij Idea 和 Kotlin Gradle 项目构建一个 jar。当我尝试配置 Artifact 时，Idea 看不到我的主类

这是我的摇篮：

plugins {
    id 'java'
    id 'org.jetbrains.kotlin.jvm' version '1.3.60'
    id 'application'
}
group 'org.vladdrummer'
version '1.0-SNAPSHOT'

sourceCompatibility = 1.8

repositories {
    mavenCentral()
}

sourceSets {
    main.java.srcDirs += 'src/main/kotlin/'
}

jar {
    manifest {
        attributes 'Main-Class': 'MovieQuizBackendKt'
    }
}

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk8"
    compile "com.sparkjava:spark-kotlin:1.0.0-alpha"
    implementation 'com.google.code.gson:gson:2.8.2'
    runtime 'mysql:mysql-connector-java:5.1.34'
    testCompile group: 'junit', name: 'junit', version: '4.12'
}

compileKotlin {
    kotlinOptions.jvmTarget = "1.8"
}
compileTestKotlin {
    kotlinOptions.jvmTarget = "1.8"
}

这是结构： …

在Gradle（5.0+）中有两种创建方法，即任务：

tasks {
    val javadocJar by creating(Jar::class) {
        val javadoc by tasks

        from(javadoc)
        classifier = "javadoc"
    }
}

和

tasks {
    val javadocJar by registering(Jar::class) {
        val javadoc by tasks

        from(javadoc)
        classifier = "javadoc"
    }
}

基本上是相同的API，有什么区别？

我有一个配置了Gradle和Kotlin的项目。这是一个命令行实用程序，我希望能够从终端运行生成的jar。但是我收到以下错误：

Exception in thread "main" java.lang.NoClassDefFoundError: kotlin/jvm/internal/Intrinsics
    at com.autentia.impt.MainKt.main(Main.kt)
Caused by: java.lang.ClassNotFoundException: kotlin.jvm.internal.Intrinsics

    at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:338)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:357)
    ... 1 more

我的gradle配置如下：

buildscript {
    ext.kotlin_version = '1.2.20'
    ext.junit_platform_version = '1.0.1'
    ext.junit_version = '5.0.0'
    ext.moshi_version = '1.5.0'
    ext.jna_version = '4.5.0'

    repositories {
        mavenCentral()
    }

    dependencies {
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath "org.junit.platform:junit-platform-gradle-plugin:$junit_platform_version"
    }
}

version '1.0-SNAPSHOT'

apply plugin: 'kotlin'
apply plugin: 'application'
apply plugin: 'org.junit.platform.gradle.plugin'

mainClassName = 'com.autentia.impt.MainKt'

repositories {
    mavenCentral()
}
