Compiler version 0.8 doesn't build on Windows (10) with sbt.version = 1.1.0-RC4
The currently required version of `sbt` contains an [already reported bug](https://github.com/sbt/sbt/issues/3871) leading to a failed build in my Windows 10. While it has been reported for Windows 10 only, I'm pretty sure it affects all Windows because the underlying cause affects all Windows. The exact stacktrace I'm seeing [has been reported](https://github.com/sbt/sbt/issues/3871#issuecomment-363927103) already as well.

Two possible solutions, while the easiest is to simply use the following line in `build.properties` and use an older version of `sbt`:

> sbt.version = 1.0.0

This fixes the problem for me, the original old version `0.13.8` didn't work because of other build errors. The interesting question is why you used `1.1.0-RC4` at all, I don't have a non-Windows build to test if other platforms need a more current version for some reason.

If something newer than `1.0.0` is really required, things get tricky, because a snapshot release containing the fix needs to be used. Instructions can be found [here](https://github.com/sbt/sbt/issues/3871#issuecomment-357934384) and [here](https://github.com/sbt/sbt/issues/3871#issuecomment-366003491). That fixed the problem for me as well.

If you go for the snapshot release, in my opinion it would be great if you could provide the line `sbt-snapshots` of the file `repositories` in some project local configuration as well if possible. That file didn't exist in my setup by default and I needed some time to find the relevant docs to know what its minimal content needs to be.
