(1)編寫相應task

在build.gradle文件夾加入buildMyJar task

task buildJar(type: Jar, dependsOn: ['build']) {

//導出的jar文件名稱

archiveName = 'aa.jar'

//從哪個目錄打包jar

from('build/intermediates/classes/release')

//導出的jar文件的存放目錄（未指定則默認存放在build/outputs/libs下）

destinationDir = file('build/outputs/libs')

//去掉不要的類

//exclude('com/aa/bb/BuildConfig\$*.class')

//exclude('**/R.class')

//exclude('**/R\$*.class')

//需要打包的類

include('**/*.class')

//include assets path

from fileTree(dir: './',includes: ['assets/**'])

include('assets/**')

}

}

(2)打開AS右側面板的gradle projects,在相應工程的other找到buildMyJar 執行即可。
