Jenkins打包android应用时自动签名apk详解

applicationVariants.all { variant ->
  if (variant.buildType.name.equals('release')) { //如果是release版本
   variant.outputs.each { output -> def outputFile = output.outputFile
   if (outputFile != null && outputFile.name.endsWith('.apk')) { //查找所有的apk
    def fileName = "${releaseTime()}_XXXXPorject_${defaultConfig.versionName}.apk" //重新定义apk的名称
    output.outputFile = new File(outputFile.parent, fileName) //outputFile.parent参数可以改成你你想要的发布路径
   }
  }
 }
}

def releaseTime() {
  // return new Date().format("yyyyMMdd", TimeZone.getTimeZone("UTC")) //年月日
  return new Date().format("yyyyMMdd HH-mm-ss", TimeZone.getTimeZone("GMT+8:00")) //年月日时分秒
}

 signingConfigs {//签名的配置
  release {
   storeFile file("签名.jks")
   storePassword '密码'
   keyAlias '别名'
   keyPassword '密码'
  }
}
