How to add environment in Grails

Question

I am attempting to add an environment to a Grails 2.4.4 app, as documented: http://docs.grails.org/2.4.4/guide/conf.html#environments

I have added configuration for this environment to all of Config.groovy, DataSource.groovy, and BootStrap.groovy as documented.

However, when I attempt to execute my unit tests in this environment with the command grails -Dgrails.env=shippable test-app --unit --stacktrace, I receive an exception that I am unable to find a cause for:

| Compiling 16 source files.
| Error Error executing script TestApp: java.lang.NullPointerException: Cannot invoke method newInstance() on null object (NOTE: Stack trace has been filtered. Use --verbose to see entire trace.)

Lines 18-28 of _Events.groovy are shown here:

        Closure installBowerNotification = {
        event 'StatusError', [
            "Failed to install front-end javascript dependencies. " +
            "If you're not working on the CMS, it's safe to ignore " +
            "this message. "
        ]
        event 'StatusError', [
            'Please install Yarn and Bower as described in the README. ' +
            '(i.e., `brew install yarn && yarn global add bower`)'
        ]
