mill 0.11.2 does not resolve the javax.media maven organization properly.

[okennedy]

Reproduction steps:

1. Create a project with a dependency on https://mvnrepository.com/artifact/org.geotools/gt-main
2. Attempt to compile the project.

In mill 0.11.1, the project compiles properly. In mill 0.11.2, the project fails with an unresolved dependency:

___.resolvedIvyDeps Failed to load dependencies
  not found: https://repo1.maven.org/maven2/javax/media/jai_core/1.1.3/jai_core-1.1.3.jar

The correct URL should be javax.media, not javax/media

[lefou]

The URL to jai_core is correct. The URL exists: https://repo1.maven.org/maven2/javax/media/jai_core/1.1.3/ but there is no binary jar, only a pom and a javadoc jar. This is not a issue in Mill but with Maven central repo1. The pom states <packaging>jar</packaging> but there is no jar file.

In Maven repositories, dots in organization names are replaced by path separators. This is a difference to Ivy repositories.

[okennedy]

It's possible it's a different issue. I can confirm that the symptom is there: The project compiles correctly under mill 0.11.1, but not under .2 I can come up with a minimal reproduction later today.

[lefou]

Yeah, a repro would be nice.

There is probably a related issue in coursier: https://github.com/coursier/coursier/issues/2377

The latest comment is about the same sympton but in sbt. They switched from sbt 1.9.3 to 1.9.4. Sbt 1.9.4 as well as Mill 0.11.2 bumped their dependencies on coursier from 2.1.4 to 2.1.6. So, seeing the same issue (paired with a nice explanation in the linked issue) in sbt and Mill indicates an upstream issue in coursier 2.1.6.

@okennedy You could try to remove the relevant path in your coursier cache and re-try.
