hello! trying to compile simple project with scala 2.13. source of project is on https://github.com/k-bespalov/pants-scala-helloworld try to compile via command

./pants compile src/main:hello --scala-version=custom --scala-suffix-version=2.13

and get error

zinc[zinc-only](src/main:hello) failed: sequence item 0: expected str instance, ArtifactClasspathEntry found
FAILURE: Compilation failure: Failed jobs: zinc[zinc-only](src/main:hello)

anybody knows what does it mean? and how I can fix it? if I remove BUILD.tools file and compile with

--scala-version=2.12

compilation is successful, but when I construct jar via

binary

command, jar doesn’t contain scala library and I get ClassNotFoundExceprion(this is my next question 😄 ). thank you in advance

which pants version are you using?

the "suffix version" is something different from the

--scala-version

, ftr: i think it would need to be the entire scala version

i am almost positive this is a very silly bug -- we switched from using strings for classpath entries to using this

ArtifactClasspathEntry

object and it looks like something is trying to make it quack like a string

but yea... possibly a bug.

pants 1.19.0

yes please!
