Recommended way to Docker build gradle and extract test results for Jenkins publishing

Question

This is what I have right now (Note: Using Buildkit):

A runtime target as the base of the final image

A build target in Dockerfile that runs ./gradlew build which of course runs tests

A test-report target based on scratch that copies the results from the build target

And a final target that copies from build into runtime

I first run the test-report target with --output to actually trigger the build and extract test results Then build the final target image

The problem is that something inconsistently bursts the cache and it builds twice.

Is there a better way to do this?
