问vasdolly多渠道打包失败，怎么处理？

命令行gradlew channelRelease多渠道打包时出错，报错信息如下

package="com.only.cloudphone" found in source AndroidManifest.xml: E:\CloudPhone\app\src\main\AndroidManifest.xml.

Setting the namespace via a source AndroidManifest.xml's package attribute is deprecated.

Please instead set the namespace (or testNamespace) in the module's build.gradle file, as described here: https://developer.android.com/studio/build/configure-app-module#set-namespace

This migration can be done automatically using the AGP Upgrade Assistant, please refer to https://developer.android.com/studio/build/agp-upgrade-assistant for more information.
