Start with build.sbt and project/plugins.sbt, then reproduce sbt run in the reported MSYS/Windows environment. Inspect the full Compile / run output and the firtool invocation at the reported cache path. Done means the gcd.GCD run completes without the firtool non-zero exit or pipe-closed exception.
