Unsupported class file major version 64

[thomas-xin]

Hi,

I have attempted to build this repo on three different gradle versions: 7.2, 8.02 and 8.2; all display the following error:

Could not open settings generic class cache for settings file 'C:\Users\[censored directory]\tensorflow-lite-examples-android\settings.gradle' (C:\Users\Thomas\.gradle\caches\7.2\scripts\dzuajkbvb0k1mlebelr004mld).
> BUG! exception in phase 'semantic analysis' in source unit '_BuildScript_' Unsupported class file major version 64

Using the --debug or --stacktrace shows a lot of console spam, but a similar message on the error line:

Caused by: java.lang.IllegalArgumentException: Unsupported class file major version 64

Is this a problem with the framework or environment variables, or does it only work on a specific gradle version?
Thanks

Update: Downgrading Java SDK versions several times later I got a different error at Java 11.0.19:

FAILURE: Build failed with an exception.

* Where:
Build file 'C:\Users\[censored directory]\tensorflow-lite-examples-android\example-model-personalization\build.gradle' line: 65

* What went wrong:
A problem occurred evaluating project ':example-model-personalization'.
> Cannot set the value of read-only property 'force' for DefaultExternalModuleDependency{group='org.tensorflow', name='tensorflow-lite-select-tf-ops', version='2.8.0', configuration='default'} of type org.gradle.api.internal.artifacts.dependencies.DefaultExternalModuleDependency.

@thomas-xin I was using Java 1.8 to compile this project. But, it seems a bit old. I just have finished upgrade work my project DevBricksX-Android. This project heavily depends on that project. So, I am going to update this one to compile with Java 17.
