builde.gradle出jar包

task clearJar(type: Delete) {
    delete 'build/libs/network.jar'这行表示如果你已经打过一次包了，再进行打包则把原来的包删掉
}

//生成jar包
task makeJar(type: Copy) {
    delete 'build/libs/tiancity.jar'
    from('build/intermediates/aar_main_jar/release/') //jar文件来源
    into('build/libs/') //生成路径
    include('classes.jar')
    rename('classes.jar', 'network.jar') //命名为network.jar
}

makeJar.dependsOn(build)
