body: <p>I cloned an existing running <code>Angular6</code> project on a new machine. When I tried to run the project in <code>Intellij</code>, I got the error <code>Unable to find any apps in .angular-cli.json</code>. I read in SO that in the filename has changed to <code>angular.json</code>. I can see <code>angular.json</code> in project. Then why am I getting this error and how can I solve it</p>
