Error loading ortools native library

[nornagon]

When trying to load the native dylibs for use with ortools, I get the following error:

java.lang.NullPointerException: Resource ortools-darwin/ was not found in ClassLoader ammonite.runtime.SpecialClassLoader@2f7c2f4f
  java.util.Objects.requireNonNull(Objects.java:259)
  com.google.ortools.Loader.getNativeResourceURI(Loader.java:40)
  com.google.ortools.Loader.loadNativeLibraries(Loader.java:118)
  ammonite.$file.solve$.<clinit>(solve.sc:4)

Here's Loader.java from ortools: https://github.com/google/or-tools/blob/5425dedcfbb22cb74c636c1374a9b5ad684b1eb5/ortools/java/com/google/ortools/Loader.java#L37

Repro:

import $ivy.`com.google.ortools:ortools-java:9.6.2534`, com.google.ortools._

Loader.loadNativeLibraries();

Unfortunately I don't have the ClassLoader-fu to figure out why ortools can't find its resource URIs :( but it seems to work fine in a regular SBT project!
