Gluon Client Maven Plugin - Resource filtering isn't working on 'client:package' - gluon

Question

I am working on a javafx 11 mobile project and Gluon client plugin is being used to build APK.
From this single project we need to build multiple apps (APKs) for different customers. I've done that using maven profiles.
Now I am trying to update 'AndroidManifest.xml' dynamically to set different package name for each builds. I've tried maven resource filtering to update that property dynamically. It's not working as expected.
Below is the 'AndroidManifest.xml' (in src/android):
<?xml version='1.0'?>
<manifest xmlns:android='http://schemas.android.com/apk/res/android'
package='${app.package.name}'
android:versionCode='${app.version.code}'
android:versionName='${app.version.name}'>
<supports-screens android:xlargeScreens="true"/>
<uses-permission android:name="android.permission.INTERNET"/>
<application android:label="${app.name}" android:icon="#mipmap/ic_launcher">
<activity android:name='com.gluonhq.helloandroid.MainActivity' android:configChanges="orientation|keyboardHidden">
<intent-filter>
<category android:name='android.intent.category.LAUNCHER'/>
<action android:name='android.intent.action.MAIN'/>
</intent-filter>
</activity>
<activity android:name='com.gluonhq.helloandroid.PermissionRequestActivity'/>
</application>
As you can see above, package, versionCode, versionName and appLabel are defined as filter variables.
Below is the manifest in "target\classes" after executing mvn client:build -P android command.
<?xml version='1.0'?>
<manifest xmlns:android='http://schemas.android.com/apk/res/android'
package='com.company.parent.app'
android:versionCode='1'
android:versionName='1.0'>
<supports-screens android:xlargeScreens="true"/>
<uses-permission android:name="android.permission.INTERNET"/>
<application android:label="CB Parents" android:icon="#mipmap/ic_launcher">
<activity android:name='com.gluonhq.helloandroid.MainActivity' android:configChanges="orientation|keyboardHidden">
<intent-filter>
<category android:name='android.intent.category.LAUNCHER'/>
<action android:name='android.intent.action.MAIN'/>
</intent-filter>
</activity>
<activity android:name='com.gluonhq.helloandroid.PermissionRequestActivity'/>
</application>
Below is the manifest in "target\client\aarch64-android\gvm\android_project\app\src\main" after executing mvn client:package -P android command.
<?xml version='1.0'?>
<manifest xmlns:android='http://schemas.android.com/apk/res/android'
package='${app.package.name}'
android:versionCode='${app.version.code}'
android:versionName='${app.version.name}'>
<supports-screens android:xlargeScreens="true"/>
<uses-permission android:name="android.permission.INTERNET"/>
<application android:label="${app.name}" android:icon="#mipmap/ic_launcher">
<activity android:name='com.gluonhq.helloandroid.MainActivity' android:configChanges="orientation|keyboardHidden">
<intent-filter>
<category android:name='android.intent.category.LAUNCHER'/>
<action android:name='android.intent.action.MAIN'/>
</intent-filter>
</activity>
<activity android:name='com.gluonhq.helloandroid.PermissionRequestActivity'/>
</application>
Because the filters are not applied as expected, the 'mvn client:package -P android' task fails.
Below is how I applied filtering for AndroidManifest in pom.xml.
<!-- To set AndroidManifest properties dynamically -->
<resource>
<directory>src/android</directory>
<!-- Map ${} into resources -->
<filtering>true</filtering>
<includes>
<include>AndroidManifest.xml</include>
</includes>
</resource>
Why is filtering not working only with 'mvn client:package' task while it works with 'mvn client:build' task? or Am I missing anything?
PS. It's also possible to update 'appLabel', 'versionCode' and 'versionName' through client plugin configuration. But I want to keep every dynamic properties in a single properties file. And also there's no option to set 'packageName' through that plugin. That's why I am updating them through resource filtering.
Update #1: Here is my pom.xml. It's not polished yet.

So, there are profiles for android, ios and for each schools. I use following maven commands for building and packaging "mvn client:build -P school1,android", "mvn client:package -P school1,android" respectively.
