When building HelloFXML package for Android I got the following error and haven't found any solution so far:

@plokhotnyuk :
I guess this new "Discussion" feature works really great - it took me almost a month to notice that you opened a new discussion :)

It looks as if you installed NDK separately from GraalVM? If yes, you may try to remove it and let GraalVM do the whole work. Or maybe you can try to follow hints from this article: https://www.graphhopper.com/blog/2020/04/14/experiments-with-graalvm-native-images-2-2/

On WSL2, I let Gluon install Android SDK and NDK by itself (shown to both have downloaded successfully) through the command "mvn -Pandroid gluonfx:build" and yet still get this exact error. I use Maven 3.8.8 and version 1.0.19 of the gluon plugin, and the only thing I changed in HelloFX was change the target in the pom.xml to android
