gradle对于spark来说，是一个打包工具，和maven、sbt工具类似。我们使用其来构建自动打包。

1，首先设置maven的本地库文件目录

2,在IDEA中构建gradle项目

2，最简配置，配置buile.gradle

group 'com.beijing.spark'version '1.0-SNAPSHOT'apply plugin : 'java'version='1'archivesBaseName="aa"  // repositories {    mavenCentral()}apply plugin: 'application'mainClassName  = 'helloJava'sourceSets {    main {        java {            srcDirs=['src']        }    }}dependencies {    compile fileTree(dir:'lib',include:'*.jar')}//依赖编译，然后打包JARtask taskJar(type:Jar, dependsOn: compileJava) {    from 'build/classes'    destinationDir = file('build/libs')}//清除上次的编译过的文件task clearPj(type:Delete){    delete 'build','target'}//把JAR复制到目标目录task release(type: Copy,dependsOn: [clearPj,taskJar]) {    from('build/libs') {        include '*.jar'    }    into ('target')}

运行结果如下

在windows cmd中运行
