title: On deploy, Heroku says it can't find API key even though I've logged in
body: <p>When I run <code>heroku deploy:jar app.jar --app app</code>, I receive this error:</p>
  
  <pre><code>$ heroku deploy:jar build/libs/app.jar --app app
  Uploading app.jar
  -----&gt; Packaging application...
         - app: app
         - including: build/libs/app.jar
   ! ERROR: Could not get API key! Please install the toolbelt and login with `heroku login` or set the HEROKU_API_KEY environment variable.
   !        Re-run with HEROKU_DEBUG=1 for more info.
   ▸    There was a problem deploying to app.
   ▸    Make sure you have permission to deploy by running: heroku apps:info -a app
  </code></pre>
  
  <p>Here's there environment's information:</p>
  
  <pre><code>On a Mac.
  Heroku version: heroku-cli/6.16.12 (darwin-x64) node-v9.11.1
  Heroku plugins: heroku-cli-deploy 0.4.0
  java version "1.8.0_131"
  node version: v4.9.1
  </code></pre>
  
  <p>I've tried running <code>heroku login</code> multiple times.  After it's run, I can run <code>heroku apps:info -a app</code> and it lists the information.  I'm inferring that that means I'm logged in already.</p>
  
  <p>My login works on another computer, so I assume it's a local config issue and not an account issue.  When I set <code>HEROKU_DEBUG=1</code>, it provides no additional information.</p>
