title: Passing multiple arguments is deprecated! Pass an options object instead
body: <p>I use gulp4 when I run 'data' task I'll get the warning:</p>
  
  <blockquote>
    <p>WARNING!! Passing multiple arguments is deprecated! Pass an options object instead.</p>
  </blockquote>
  
  <pre><code>// Build data json
  gulp.task('data', () =&gt; {
      return 
        gulp.src([ '**/*.yml', '!**/_*.yml' ], 
        { cwd: 'source/modules/*/data' })
          .pipe($.plumber(options.plumber))
          .pipe($.yaml({ space: '\t' }))
          .pipe($.mergeJson('data.json'))
          .pipe(gulp.dest('tmp'));
  });
  </code></pre>
  
  <p>If I remove <code>.pipe($mergeJson)</code>, the warning won't notify
  What am I missing?</p>
