Build fails at the step "finishing build rules" with: produces files inside mainline_system.mk artifact path requirement

Hi,

trying to build aosp_x86_64-userdebug lunch combo on android-10.0.0_r40 with opengapps/aosp_build.
Unfortunately the build fails while verifying that nothing else produces files inside the artifact path requirement.
build/make/core/main.mk:1414: error: Build failed.
error.txt

Is there something I am missing?
Tried to disable the check without success.

Cheers

Solution:
Add all conflicting files to the whitelist of the build target mk.
Builds run through fine.

Cheers,
Yanni
