Gradle生成Jar的两种方式小结

task copyDependencies(type: Copy) {
    from configurations.runtime
    into 'build/libs/lib'
}
jar.dependsOn(copyDependencies)
jar {
    manifest {
        attributes "Implementation-Title": project.name
        attributes "Implementation-Version": '1.0.0'
        attributes 'Main-Class': 'Test'
    }
    if (!configurations.runtime.isEmpty()) {
        manifest.attributes('Class-Path': '. lib/' + configurations.runtime.collect { it.name }.join(' lib/'))
    }
}

jar {
    String someString = ''
    configurations.runtime.each {someString = someString + " lib//"+it.name}
    manifest {
        attributes 'Main-Class': 'Program'
        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
}

jar {
    archivesBaseName = 'MiniRPC'//基本的文件名
    archiveVersion = '0.0.3' //版本
    manifest { //配置jar文件的manifest
        attributes(
                "Manifest-Version": 1.0,
                'Main-Class': 'com.mirs.minirpc.App' //指定main方法所在的文件
        )
    }
 //打包依赖包
    from {
        (configurations.runtimeClasspath).collect {
            it.isDirectory() ? it : zipTree(it)
        }
    }
}
