I found the issue, it was a mis-placed } . I closed the "build" goal before configuration , which was causing the issue.Corrected angular.json :

Having the same issue here, but angular.json is not the problem in my case (same PC, parallel project with same angular.json file works just fine).
I think it's due to package.json instead, which are different, after running npm install

I have a basic angular application , which was working fine. The
ng serveandng testcommands were working fine. Recently as part of build automation for different environments , I introduced some configuration changes to allow differentenvironment.tsfiles to be loaded as per environment . For that I edited theangular.jsonfile.After the changes , theng serveandng testcommand fails to execute. Whenever the commands are executed the following error is thrown :An unhandled exception occurred: No projects support the 'test' target. See "C:\Users\account\AppData\Local\Temp\ng-BlbvgV\angular-errors.log" for further details.The modified
