Not able to access web-app folder files in Grails 3
<p>I am not able to access web-app folder files in Grails 3.
I have <code>robots.txt</code> in the web-app folder and in Grails 2 I was able to access it directly at <code>http://localhost:8080/robots.txt</code>. After migrating to Grails 3 I am not able to access it anymore at <code>http://localhost:8080/robots.txt</code>.</p>

<p>How can I make these files accessible again?</p>
