Building Android App Bundle fails with `Task 'bundle' not found`

[Marc_Van_Daele]

I'm trying to build an Android App Bundle from QtCreator.
I'm using Qt5.14.1, platform-29 and NDK 21.0.
Building an empty QML project works fine and results in an aab file

However, building my own project fails with

FAILURE: Build failed with an exception.

* What went wrong:
Task 'bundle' not found in root project 'android-build'. Some candidates are: 'build'.

* Try:
Run gradlew tasks to get a list of available tasks. Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.
Building the android package failed!

gradlew tasks looks like below and indeed doesn't contain a 'bundle' task

Build tasks
-----------
assemble - Assembles all variants of all applications and secondary packages.
assembleAndroidTest - Assembles all the Test applications.
assembleDebug - Assembles all Debug builds.
assembleRelease - Assembles all Release builds.
build - Assembles and tests this project.
buildDependents - Assembles and tests this project and all projects that depend on it.
buildNeeded - Assembles and tests this project and all projects it depends on.
clean - Deletes the build directory.
compileDebugAndroidTestSources
compileDebugSources
compileDebugUnitTestSources
compileReleaseSources
compileReleaseUnitTestSources
mockableAndroidJar - Creates a version of android.jar that's suitable for unit tests.

where the empty QML project did contain a bundle task

Any ideas? Suggestions on how to proceed from here?

Apparently, I had an older gradlew hanging around which interfered
