Bloop: Exception thrown in compilation on Windows

[Arthurm1]

I get an exception on Windows when I create an error in a Java file and Bloop attempts to recompile.

This doesn't happen on Linux.

I'm using version 1.3.4

 Unexpected error when compiling gradtest-test: 'Unexpected internal error near index 1

Thanks for reporting! Are you using WSL or Cygwin? Also, can you share the classpath for gradtest-test?

[Arthurm1]

Using Windows 7. No WSL or Cygwin.

I've attached all projects json files as txt (I hope)
Classpath is...

        "classpath" : [
            "E:\\gradtest\\.bloop\\gradtest\\build\\classes",
            "C:\\Users\\ArthurM\\.gradle\\caches\\modules-2\\files-2.1\\org.scala-lang\\scala-library\\2.12.10\\3509860bc2e5b3da001ed45aca94ffbe5694dbda\\scala-library-2.12.10.jar"
        ]

gradtest-test.txt
gradtest.txt

[jvican]

Can you also run compile on the offending target with --verbose? It will print logs that will be helpful to figure out what's wrong.

Thanks a lot for that log! Hope I'll be able to look into this soon :+1:

I found a fix for this issue @Arthurm1, will add it to a big PR and then merge it.
