classgraph: Classgraph can't find percent-encoded Coursier paths for private repositories

I’m using classgraph to resolve artifacts in sbt project with coursier.

We have two dependency types:

1. Pusblished on public repositories
2. Published on our private repository

While running under JDK 10 (OpenJDK 64-Bit Server VM Zulu10.3+5 (build 10.0.2+13, mixed mode)) within SBT or under Idea classgraph fails to resolve any classes from private repo artifacts.

At the same time it resolves these classes without an issue in case I gather all the dependencies manually into a directory and run java providing them all as classpath entries.

I’m almost sure that this is happening because of crappy directory naming convention used by coursier:

/Users/<user>/Library/Caches/Coursier/v1/https/<username>%40<company>.com%40<company>.jfrog.io/<company>/<repo>/com/<company>/<artifact>/<version>/<name>.jar

Seems like classgraphs fails to scan directories with % in name.

All such jars are completely missing from classgraph debug output.
