Reflections exception thrown on test startup

When I run my tests in IntelliJ 2017.1.3 on Linux, I get this output:

[main] WARN org.reflections.Reflections - could not create Vfs.Dir from url. ignoring the exception and continuing

This doesn’t show up when I run gradle test, so maybe it’s specific to the JUnit test runner in IntelliJ, but the exception still originates from kotlintest. Downgrading to 1.3.7 removes this error, and using any of 2.0.x causes this message to reappear.

Hi! On kotlintest 2.0.7 and running gradle, and seeing the same issue. Just updated to High Sierra, so I believe that may be the issue. I think the error is in reflections as ronmamo/reflections#80 states. But if there is anything that can be done here, that would be great.

Be happy to help if you point i the right direction as well.

Cheers, Alf

3.0.0-RC3 should be fixed. I have tested it on travis, locally, windows and linux and after the latest fixes I don’t see this error anymore.
