$ go run main.go orb source circleci/gradle

commands:
  with_cache:
    description: |
      Run a set of steps with gradle dependencies cached.

      This command will first restore a cache of gradle dependencies, if one was
      saved by a previous build. The provided `steps` will then be executed, and
      if successful, then a fresh cache will be saved, if required.

      The contents of the `~/.gradle` directory is cached, which will substantially
      improve build times for projects with many dependencies.

      The cache-key is generated from any files named `build.gradle` that are
      present in the `working_directory`.
    parameters:
      steps:
        type: steps

      - run:

Error: Failed to get source for 'circleci/gradl': graphql: Non-nullable field was null.
exit status 255

This is looking good!

I think we should wrap the graphql error in the CLI. That response makes a user error look like a server error.

[marcomorain]

This is a server error as far as I can tell.

I'll make a follow up ticket for this. LGTM
