While compile errors may be reproduced that way, it's hard to run any tests due to the required softlink to the compiled binaries. It is possible, but very inconvenient to use and thus it renders reproducing test results very hard.
I have been thinking about giving the possibility to download the generated artefacts during build stage - for debugging reasons only! This way, they can be used in conjunction with unit tests to reproduce a test failure, but this still needs some discussions and a security review. -Marco Am 06.01.2018 12:59 nachm. schrieb "kellen sunderland" < kellen.sunderl...@gmail.com>: > Regarding the comments around reproducibility, what parts of the CI are > people having trouble reproducing now?
