Module org.junit.jupiter.api not found, even when specified in ivyDeps

[ayhon]

I have a mill project with two modules, one written in Java and another one written in Scala, where the Scala module depends on the Java one. My team is in charge of the Scala and we're using mill as our build system. The Java team instead seems to be using Ecilpse to handle the builds of their project.

I wanted to also include their code inside our build.sc file so that I could assemble our code with their code into a Jar file which we could then upload to a server. Recently, they added JUnit5 to handle their tests, and they did so as a runtime dependency, not only for development. Arguably our module shouldn't need to care about what testing framework the other team is using, but in the interest of speed I decided to include it in the build.sc anyways. Nevertheless, I was surprised what I found myself unable to do so.

Their module is called language. Whenever I run mill language.compile I get the following error message

[info] compiling 1 Java source to /home/ayhon/uni/soft-proj/projet-gl/out/language/compile.dest/classes ...
[error] /home/ayhon/uni/soft-proj/projet-gl/language/src/module-info.java:9:1: module not found: org.junit.jupiter.api
[error] org.junit.jupiter.api
1 targets failed
language.compile javac returned non-zero exit code

The build.sc which I'm using is the following:

import mill._, scalalib._
import $ivy.`com.lihaoyi::mill-contrib-scalapblib:`
import contrib.scalapblib._

val ScalaVersion = "3.5.2"
val ScalaPBVersion = "0.11.17"

object server extends ScalaPBModule {
  // ...  
  def moduleDeps = Seq(language)
  // ...
}

object language extends JavaModule {
  def ivyDeps = Agg(
    ivy"org.junit.jupiter:junit-jupiter-api:5.11.3"
  )
}

From what I've been able to tell, org.junit.jupiter.api corresponds to https://mvnrepository.com/artifact/org.junit.jupiter/junit-jupiter-api. Nevertheless, mill seems to complain that it has not been specified. Has this something to do with how mill interacts with module-info.java?

I don't think Mill treats module-info.java files specially. Would it be possible for you to minimize a reproduction I could look at? At a glance I don't see anything obviously wrong with what you are doing.
