在使用Gradle打包成一个可运行的Jar包的时候，需要把编译时依赖的库也打包进去，因此要搞清楚打包时如何才能将库文件打包进去。

对于implementation引入的库，则需要如下的语句：

from {
        configurations.runtimeClasspath.collect { it.isDirectory() ? it : zipTree(it) }
    }

对于testImplementation引入的库，则需要如下的语句：

from {
        configurations.testRuntimeClasspath.collect { it.isDirectory() ? it : zipTree(it) }
    }

我们只需要打包运行时的依赖包即可，则完整build.gradle如下：

plugins {
    id 'java'
    id 'org.jetbrains.kotlin.jvm' version '1.3.21'
}

group 'com.zhuyanbin'
version '1.0.0'

sourceCompatibility = 1.8

repositories {
    mavenCentral()
}

jar {
    manifest {
        attributes 'Implementation-Title' : 'DropBox-Backup-Service'
        attributes 'Manifest-Version': '1.0.0'
        attributes 'Main-Class': 'com.zhuyanbin.dropbox.AppKt'
    }

    from {
        configurations.runtimeClasspath.collect { it.isDirectory() ? it : zipTree(it) }
    }
}

dependencies {

    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk8"
    implementation 'com.dropbox.core:dropbox-core-sdk:3.0.10'
    implementation 'commons-configuration:commons-configuration:1.9'
    testImplementation group: 'org.junit.platform', name: 'junit-platform-launcher', version:'1.4.0'
    testImplementation group: 'org.junit.jupiter', name: 'junit-jupiter-engine', version:'5.4.0'
    testImplementation group: 'org.junit.vintage', name: 'junit-vintage-engine', version:'5.4.0'
}

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