Could not findproperty 'packageApplication'

由于gradle 升级导致兼容问题解决方法

Error:Could not findproperty 'packageApplication' oncom.android.build.gradle.internal.api.ApplicationVariantImpl_Decorated@5fc07ff0.

Couldnot find property 'zipAlign' on com.android.build.gradle

（1） 

def apk = variant.packageApplication.outputFile;
def newName = "";

修改为：

 def apk = variant.outputs[0].outputFile;
 def newName = "";

（2）

 variant.packageApplication.outputFile = new File(apk.parentFile, newName);
 if (variant.zipAlign) {
        newName = newName.replace("-unaligned", "")
        log.info "$newName"
        variant.zipAlign.outputFile = new File(apk.parentFile, newName);
 }

修改为： 

 variant.outputs[0].outputFile= new File(apk.parentFile, newName);
  if (variant.outputs[0].zipAlign) {
        newName = newName.replace("-unaligned", "")
        log.info "$newName"
        variant.outputs[0].zipAlign.outputFile= new File(apk.parentFile, newName);
  }
