Where to find generated error reports? (/layers.../svm_err...md)

[tabiStein]

I'm trying to build a native image using the Spring Maven plugin with paketobuildpacks. The build-image goal fails, telling me that there is a generated error report I should inspect. However, I don't see it anywhere on my computer (it doesn't seem to be a valid absolute path or relative path from my project).

Where should I be able to find this error report? Is it located in some Graal temp directory outside of my project?

In case it's relevant, here is the command I'm running: mvn -Pnative spring-boot:build-image
I copied the native profile from spring-boot-starter-parent, as follows:

hi @tabiStein, tbh seems like the Paketo folks should be able to answer this?
