When running the cachebuild ("grunt-cache-bust": "~1.7.0",) task I am getting the following:

Warning: Task "cacheBust" not found. Use --force to continue.

In the log console when using -v on grunt.
Registering "grunt-cache-bust" local Npm module tasks.

I also have this issue. Set the version back to 1.6.0 as an immediate fix
