Tests are failing randomly on Travis CI. I couldn't reproduce it locally, will take a look later.

Hey 🙂

I'm interested in using this with 2.13.1, so I looked at the failing runs on Travis and it seems that the .unsafeRunTimed(10.seconds) in the tests is a little too short. Locally I could reproduce the same errors by reducing it to 8.seconds.

Maybe we can just increase the timeout to 15.seconds and get this up and running?

[azolotko]

@felixbr the last attempt was .unsafeRunTimed(30.seconds), but it still fails randomly. I suspect the problem is bigger than just the properly set timeout.

It seems like I fixed the issue over at #8 🎉

Feel free to cherry-pick my commit onto your PR, as you've done the bulk of the work 🙂

I think you shouldn't update sbt in this PR. If you insist to update sbt, I recommend to use 1.3.4 instead of 1.3.5, as the latter has class loading issues.

@felixbr Thanks Felix. I've also figured this out. The hard way :)

@felixbr The TravisCI build is still failing...

Hm strange, my debug PR (#8) worked on the first try 🤔

[azolotko]

@felixbr Great. I'll then just close mine and you can remove [WIP | Travis-Debug] from yours and let's hope it'll get merged soon.
