A build.gradle全局常量：

•  //根路径def ROOT_PATH = rootProject.rootDir.pathdef GROUP = "com.genialsir.mobileads"def MOB_SDK_VERSION_NAME = "1.1.2"
  复制代码

B 在当前库项目的build.gradle文件中android{}中配置如下：

• //自定义aar名称android.libraryVariants.all {variant ->variant.outputs.all {def fileName = GROUP + "." + MOB_SDK_VERSION_NAME +   ".aar"outputFileName = fileName}}
  复制代码

C 借助命令生成arr到指定的目录：

•  使用gradle -b **（代表当前Project或Module目录名）/build.gradle aarRelease
  复制代码

在对应build.gradle文件中配置如下：

1. 生成所需要的目录

•   //生成对应目录task makeLibDir() {def outputPath = ROOT_PATH + '/aar_release'//脚本指定路径if(project.hasProperty('OUT_PUT_DIR_PATH')){outputPath = "${OUT_PUT_DIR_PATH}"}//创建aar所输出的目录createDir(outputPath)
  }
  复制代码

1. 代码参数块

•  def createDir = {path ->File dir = new File(path)if (!dir.exists()) {dir.mkdirs()}println "Generate the corresponding directory path is" + dir.toString()
  }
  复制代码

1. 拷贝AAR

•  task copyAAR(type: Copy) {println "----------> ARR copy start <-----------"def buildPath = ROOT_PATH + '/containerad/build/outputs/aar'//AAR所在的编译路径from buildPath//AAR所拷贝的目录def outputPath = ROOT_PATH + '/aar_release'println "outputPath = " + outputPathinto outputPathprintln "----------> ARR copy succeeded <-----------"
  }
  复制代码

1. 执行copyAAR

•  tasks.withType(JavaCompile) {compileTask -> compileTask.dependsOn(copyAAR)
  }
  复制代码

1. 使用命令执行**(gradle -b 目录名/build.gradle aarRelease)**并发布AAR

•  task aarRelease(type: Copy) {//任务开始println "----------> AAR Release Task Start <----------"//AAR所在的编译路径def buildPath = ROOT_PATH + '/containerad/build/outputs/aar'//AAR输出路径def aarOutPath = ROOT_PATH + "/aar_release"//广告的SDKdef adPath = buildPath + GROUP + "." + MOB_SDK_VERSION_NAME + ".aar"//封装数组def modulePaths = [adPath]//删除AAR输出目录println "Delete -> " + aarOutPathdelete aarOutPath//循环删除各个AAR编译目录for (path in modulePaths) {println "Delete -> " + pathdelete path}//执行编译AAR脚本（原生脚本）dependsOn 'assembleRelease'//循环拷贝AAR到ARR输出目录for (path in modulePaths) {//显示开始拷贝println "-> Start of current copy <-"//当前目录println "From : " + pathfrom path//拷贝至 aarOutPathprintln "Into : " + aarOutPathinto aarOutPath;//显示当前拷贝结束println "-> End of current copy <-"}//任务结束println "----------> AAR Release Task End <----------"
  }
  复制代码

（上面内容写的有些繁琐与重复，灵活性相对差些，如果需要外部指定对应版本与目录，以及通过git灵活打对应需求的版本则就略差一些。）

####先来张最近奥迪漏油事件皮一波，免费打打广告

好的，开始进入正题，首先灵活指定版本号，通过协定OUT_PUT_AAR_VERSION_SUFFIX来指定所需版本。

  //自定义aar名称
android.libraryVariants.all {variant ->variant.outputs.all {def fileNameif (!project.hasProperty('OUT_PUT_AAR_VERSION_SUFFIX')) {fileName = GROUP + "." + MOB_SDK_VERSION_NAME + ".aar"}else{fileName = GROUP + "." + "${OUT_PUT_AAR_VERSION_SUFFIX}.aar"}outputFileName = fileName}
}
复制代码

指定对应的生成目录以及版本号

  使用默认路径命令执行(gradle -b containerad/build.gradle aarRelease)脚本指定版本号与对应目录(gradle assemble -P OUT_PUT_AAR_VERSION_SUFFIX=1.1.2 -P OUT_PUT_DIR_PATH=H:\AndroidProject\ADPlugIn\OnlyLadyAD\ad_release_path aarRelease)
复制代码

• 通过协定好的OUT_PUT_DIR_PATH与OUT_PUT_AAR_VERSION_SUFFIX来控制版本号与路径。

  task aarRelease(type: Copy) {
  //任务开始
  println "----------> AAR Release Task Start <----------"//执行编译AAR脚本（原生脚本）
  dependsOn 'assembleRelease'//AAR所在的编译路径
  def buildPath = ROOT_PATH + '/containerad/build/outputs/aar/'
  //AAR输出默认路径
  def aarOutPath = ROOT_PATH + '/aar_release'
  //脚本指定路径
  if(project.hasProperty('OUT_PUT_DIR_PATH')){aarOutPath = "${OUT_PUT_DIR_PATH}"
  }//广告的SDK
  def adPath
  if (!project.hasProperty('OUT_PUT_AAR_VERSION_SUFFIX')) {//默认版本adPath = buildPath + GROUP + "." +   MOB_SDK_VERSION_NAME + ".aar"
  }else{//脚本指定版本adPath = buildPath + GROUP + "." +     "${OUT_PUT_AAR_VERSION_SUFFIX}.aar"
  }//封装数组
  def modulePaths = [adPath]//当前AAR输出目录
  println "The current aar output directory is " + aarOutPath
  delete aarOutPath
  //循环删除已存在的aar
  for (path in modulePaths) {println "Delete ---> " + pathdelete path
  }//循环拷贝AAR到ARR输出目录
  for (path in modulePaths) {//显示开始拷贝println "-> Start of current copy <-"//当前目录println "From : " + pathfrom path//拷贝至 aarOutPathprintln "Into : " + aarOutPathinto aarOutPath;//显示当前拷贝结束println "-> End of current copy <-"
  }
  dependsOn 'assembleRelease'//任务结束
  println "----------> AAR Release Task End <----------"
  }
