Building the kotlin example fails:

after some time:

So it seems :native-client:installDist wants JRE version 11, but :stub-lite cannot deal with anything older than 17.

One finds that gradle has downloaded 4 JDKs (not sure why):

$ ls ~/.gradle/jdks/
CACHEDIR.TAG                                     OpenJDK11U-jdk_x64_linux_hotspot_11-any#20vendor-11.0.29_7.tar.gz
eclipse_adoptium-11-amd64-linux.2                OpenJDK11U-jdk_x64_linux_hotspot_11-any#20vendor-11.0.29_7.tar.gz.lock

eclipse_adoptium-17-amd64-linux.2.reserved.lock

I modified the file native-client/build.gradle.kts

which contains the line

kotlin { jvmToolchain(11) }

to read:

kotlin { jvmToolchain(17) }

This seems to fix the problem
