Recently I upgraded to angular CLI 6.0.1. After upgrading the Angular IDE for Webclipse would no longer run my project called “test-a”. It would give me the error “Project test-a is not an Angular CLI project”. I believe the problem roots with the change Angular made to .angular-cli.json. In Angular CLI 6.0.+ .angular-cli.json was renamed to angular.json. To get the Angular IDE for Webclipse to work again I had to create a soft link in the file system.
