android 项目打包jar

android项目打包成aar很简单，在app的build.gradle中改变apply的类型，然后build就可以打包aar

apply plugin: 'com.android.library'

打包成jar，同样需要上步操作，但是还需要在app的build.gradle中android{}标签下增加一些task

    def SDK_DES = "build/outputs/jar/"
    def JAR_FILE = "build/intermediates/bundles/release/classes.jar"
   def JAR_NAME = "name"
    task delBuild(type: Delete) {
        delete JAR_NAME+ ".jar"
    }

    task makeJar(type: Jar) {
        from zipTree(JAR_FILE)
        baseName = JAR_NAME
        destinationDir = file(SDK_DES)
    }
    makeJar.dependsOn(delBuild, build)

然后就可以看见在右侧gradle中 <编译module>/Tasks/other/这两个选项了,

先点击delBuild删除当前jar,然后makejar生成jar，
