[Interest] Android Build fails with Gradle qtGradlePluginType

[Daniel Brunner]

Hi,

I am using a self-compiled packaged version of Qt6 for android aarch64 and
I experience some issues in the build process after my Qt C++ native code
has been compiled successfully.

The part where it should make an APK out of it fails (see output below)

What can I do in this case?

I am using this packaging of Qt6:
https://aur.archlinux.org/packages/android-aarch64-qt6-base
https://aur.archlinux.org/packages/android-aarch64-qt6-declarative

Best regards
