caching - Docker Build using Buildkit any way to log which file burst the cache?

Question

In gradle, tests are run as part of the build, so I use a test report target from "scratch" to copy the test results from the "build" target. For some reason on some of my builds the cache is burst when I do this and it re-runs the entire build again! I know it's probably something being written outside of .dockerignore, but I have no idea what. Is there any way to log which file(s) burst the cache?
