Hello. I'm far from being an expert (and not using Java nor Kawa atm)
but after trying to reproduce your project structure I think it's a
problem of how "kawa.import.path" is resolved.
2 things seem to work:
1) If you can, instead of -Dkawa.import.path="./src/*.scm" use an
absolute path (e.g.):
-Dkawa.import.path="/home/user/development/project_name/src/*.scm"
2) If you must use a relative path:
1. Use: -Dkawa.import.path="./*.scm"
2. Start repl from inside the src directory
I just skimmed rapidly through it and I may be wrong but I think the
section "19.6.2 Searching for source files" in the Kawa manual expains
how this works.
