I edited my predef.scala file to add the following:

load.ivy("org.spire-math" %% "jawn-ast" % "0.8.3")
load.ivy("org.spire-math" %% "cats" % "0.1.2")

When I ran amm the first time I saw this output:

However on subsequent runs things are fine, and the libraries are available. It seems like problem only occurs the first time a library is added. I got similar output in the REPL:

The library seems to have been loaded correctly in this case.

That may require an Ivy API wizard. Switching to coursier would fix that too (see #110).

Yeah swapping to coursier would fix this. @alexarchambault my preferred way forward would be to make it swappable, the same way FrontEnd is now swappable, and let people bootstrap coursier via a load.ivy using the default resolver and use that from then on.

Fix #144 by overriding ivy method, rather than adding dummy resolvers…
Loading status checks…

…, because the dummy resolver with `null` as a name seems to make travis fail (???)
