android gradle 3.1后gradle打包jar

1.gradle 3.1 后build module后在build文件找不到jar文件的路径，只能找到aar的文件

2.我们可以拿到aar文件的jar文件使用

moduel:build.gradle 我们可以这样:

//aar的文件路径

def zipFile = file('build/outputs/aar/xxxx-release.aar')

//解压得到的jar的文件路径

def unzipFile = file('build/outputs/xxxx/classes.jar')

task makeJar(type: Jar) {

//解压aar拿到里面的jar文件跟assets资源文件

        copy {

                    from zipTree(zipFile)

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

                    into('build/outputs/xxxx/')

                    include('classes.jar')

                    include('assets/**')

        }

        from zipTree(unzipFile)

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

        baseName = SDK_BASENAME + SDK_VERSION

        destinationDir = file("build")

}

makeJar.dependsOn(build)
