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);

}
