I'm running into an error when I use the latest igpublisher from build.fhir.org. Unless I'm reading it wrong, it looks like it's getting an NPE when looking up http://loinc.org?

I think this is happening when it's trying to expand a value set that has this rule:

"compose" : {
    "include" : [
      {
        "system" : "http://loinc.org"
      }
    ]
  }

This is the same as in the example value set for Observation.code, so I think it is valid (and in fact, worked fine with the v3.3 publisher jar).

Ah. Seems like this general error has already been reported over at: https://chat.fhir.org/#narrow/stream/9-committers/subject/Build.20Error/near/164672

Tx server is reportedly back up, but I still get this error.

Chris Moesel (Jul 16 2018 at 13:48):

This is resolved with the latest igpublisher.jar.
