修改aar的名字

直接上代码：

  android.libraryVariants.all { variant ->
        println("variant===================")
        println(variant)
        println(variant.buildType)
        println(variant.buildType.name)
        if (variant.buildType.name.equals('release')) {//在release包的时候才修改
            variant.outputs.each { output ->
                println("output===================")
                println(output)
                println(output.outputFile)
                new File(output.outputFile.parent).deleteDir()//删除当前目录下的现有文件
                def outputFileName = "xxxxxx.aar"
                output.outputFile = new File(output.outputFile.parent, outputFileName)
            }
        }
    }
