Javac and scalac warnings as errors only for certain types

Question

I know that with -Werror and -Xfatal warnings I can make warnings like errors, but can I still see all the warnings in the compilation output, but only some of them become errors?

Answer 1

I don’t think so, only scalac .

Perhaps you can add post-build validation to your build scripts that grep displays for warnings about your critical classes and fails if they are found?
