在IDEA中使用gradle配置打可执行jar包[可执行jar与其所依赖的jar分离]

下面是我的项目的build.gradle文件的所有内容，注意高亮部分是关键：

group 'com.xbs'
version '1.0-SNAPSHOT'

apply plugin: 'java'
apply plugin: 'idea'

sourceCompatibility = 1.8

ext {
    profile = System.getProperty("env") ?: "dev"
    println "[current profile]:" + profile
}

    compile 'com.mashape.unirest:unirest-java:1.4.9'
    testCompile group: 'junit', name: 'junit', version:'4.12' }

sourceSets {
    main {
        resources {
            srcDirs = ["src/main/resources", "env/$profile"]
        }
    }
}

jar { String someString = ''
    configurations.runtime.each {someString = someString + " lib//"+it.name}
    manifest {
        attributes 'Main-Class': 'com.xbs.AppMain'
        attributes 'Class-Path': someString
    }
}
//清除上次的编译过的文件
task clearPj(type:Delete){
    delete 'build','target' } task copyJar(type:Copy){ from configurations.runtime into ('build/libs/lib')
}
//把JAR复制到目标目录
task release(type: Copy,dependsOn: [build,copyJar]) {
// from 'conf'
// into ('build/libs/eachend/conf') // 目标位置
}

展开右侧的Gradle侧边栏，找到在other下可以看到clearPj,copyJar以及release，双击release即可打jar包（它默认会执行copyJar，就是把所有的第三方依赖包放到lib目录下）：

如果看到控制台输出"BUILD SUCCESSFUL"，说明打包成功：

 

打好的jar默认放在项目中的build目录中：

 打开jar包所在目录，可以使用反编译工具查看jar包中的目录结构和文件内容：

 打开命令行窗口，使用java -jar命令来执行jar包：
