Credentials from env don't support multiple variables

[kubukoz]

e.g.

{
  "url": "REDACTED",
  "httpCredentials": "${ARTIFACTORY_USER}:${ARTIFACTORY_TOKEN}"
}

will attempt to resolve a single variable named ARTIFACTORY_USER}:${ARTIFACTORY_TOKEN, failing with:

Unable to expand variable `ARTIFACTORY_USER}:${ARTIFACTORY_TOKEN` to an environment variable or system property: (pwd)smithy-build.json [7, 28]

That's unfortunate. In the meantime you may be able to combine them into a single environment variable in whatever is calling the smithy build.
