Help compiling Android source code on Mac

[nikos2wheels]

I tried to follow the steps posted on the OsmAnd website

https://osmand.net/docs/technical/build-osmand/how-to-compile-the-android-version/?current-os=ios&

related to how to compile the Android version.

I have Android Studio installed and also the NDK tools and I exported the ANDROID_SDK, ANDROID_NDK and ANDROID_HOME environment variables with the correct paths.

When I type:

./gradlew assembleNightlyFreeLegacyFatDebug

I get the following error:

FAILURE: Build failed with an exception.

* What went wrong:
BUG! exception in phase 'semantic analysis' in source unit '_BuildScript_' Unsupported class file major version 67
> Unsupported class file major version 67

* Try:
> Run with --stacktrace option to get the stack trace.
> Run with --info or --debug option to get more log output.
> Run with --scan to get full insights.
> Get more help at https://help.gradle.org.

BUILD FAILED in 491ms

I googled this and one possible reason is that the JDK and gradle versions are not compatible. On my system I have JDK 23 and gradle 8.9 which I searched again and they are not compatible. How do I proceed to solve this issue, just upgrade to the latest Gradle?
