Cannot load.ivy where a classifier is required

[laurencer]

In sbt you can normally specify the classifier - e.g.

libraryDependencies ++= "net.sf.json-lib" % "json-lib" % "2.4" % "jdk15"

This doesn't work with load.ivy and its not clear how to load a JAR which requires a classifier.

This is fixed as of 662859f, which allows you to use coursier to add a classifier:

@lihaoyi How is this supposed to work with the new version:
Welcome to the Ammonite Repl 2.2.0 (Scala 2.13.3 Java 1.8.0_252)

I see there's now a coursierapi, where Dependency and Module live, but not Attributes.

I found something that works.

interp.load.ivy(
      "edu.stanford.nlp"              %  "stanford-corenlp"     % "4.2.0",
      Dependency.of("edu.stanford.nlp", "stanford-corenlp", "4.2.0").withClassifier("models"),
      Dependency.of("edu.stanford.nlp", "stanford-corenlp", "4.2.0").withClassifier("models-english")
  ) 

would be nice if the syntax would more closely match what's used in SBT for simple copy-paste testing, like:

SBT:
      "edu.stanford.nlp"              %  "stanford-corenlp"     % "4.2.0",
      "edu.stanford.nlp"              %  "stanford-corenlp"     % "4.2.0" classifier "models" classifier "models-english"

to translate to:

interp.load.ivy(
      "edu.stanford.nlp"              %  "stanford-corenlp"     % "4.2.0",
      "edu.stanford.nlp"              %  "stanford-corenlp"     % "4.2.0" classifier "models" classifier "models-english"
)

or, even if it needs to be duplicated, something like:

interp.load.ivy(
      "edu.stanford.nlp"              %  "stanford-corenlp"     % "4.2.0",
      "edu.stanford.nlp"              %  "stanford-corenlp"     % "4.2.0" classifier "models",
      "edu.stanford.nlp"              %  "stanford-corenlp"     % "4.2.0" classifier "models-english"
)

would be nice, if possible.
