NoClassDefFoundError: munit/Test since 0.40.15

Question

NoClassDefFoundError: munit/Test since 0.40.15

rtjfarrimond opened this issue a year ago · comments

I have a project that has been using version 0.40.14 for testcontainers-scala-munit and testcontainers-scala-postgresql. Recently scala-steward raised a PR to increase the version to 0.40.17 which caused a CI build failure; there are no other changes in the PR other than the version bump. I have tested back to 0.40.15 and seen the same issue for each version.

The error that I am seeing is java.lang.NoClassDefFoundError: munit/Test. The compiler suggests trying to use ClassLoaderLayeringStrategy.Flat, but that has not helped. When I switch the version back to 0.40.14 the issue is fixed.

Try using Munit 1.0.0-M8 with 0.40.15+

Thanks, that does get over that error! Unfortunately we also depend on munit-cats-effect, which does not seem to have a fix out yet. This issue does seem to be resolved though so happy to close. Thank you!
