title: How can I suppress the "No files matching the pattern" message in ESLint?
body: <p>In my CI setup, I have a test that runs eslint against all JS files. If no JS files exist, it's currently throwing an error. I'd prefer if it'd succeeded when no JS files exist. Is this possible?</p>
  
  <pre><code>$ eslint "./src/assets/scripts/**/*.js"
  
  Oops! Something went wrong! :(
  
  ESLint: 5.7.0.
  No files matching the pattern "./src/assets/scripts/**/*.js" were found.
  Please check for typing mistakes in the pattern.
