I ran it using the gradle commands in cmd as well as building it via IntelliJ and faced the same error.

The master branch uses a deprecated gradle version 3.5.

Try to build the develop branch. It is upgraded to the last gradle version and it uses the gradle wrapper. Soon the develop branch will be merged into master for the release 1.8 and this will be fixed.
