steps

1. Create sbt project with name:="foo"
2. On clean machine with only java and sbt script (or you can use github action with sbt/setup-sbt@v1)
3. NAME=$(sbt --no-colors --error 'print name' | head -n1)

problem

NAME is copying runtime jar...

expectation

NAME should be foo

workaround

Run sbt first.

notes

but there are more instances of echo

Wrapper scripts should never write to stdout, use stderr instead.
