VideoJs-Vast-plugin doesn't get initialized.

I have gone through the documentation still VIDEOJS: ERROR: Unable to find plugin: ads error is comming.
I am using Videojs v5.4

var myPlayer = videojs('example-video', {
plugins: {
ads: {},
vast: { url: 'http://theonion.github.io/videojs-vast-plugin/onion_sample.xml' } } } );
