Grails 3.2: Bootstrap.groovy is not executed when run as an executable war/jar file

Ran into an issue yesterday when running my grails application as an executable jar file via the command below in that it wouldn't execute the Bootstrap.groovy file. Here I had some domain objects that were used to populate the database with static data.

>java -Dgrails.env=prod -jar build/libs/my-app.war

The issue turned out to be that the Bootstrap.groovy file was not under a package name, it was sitting under

grails-app
        init
             BootStrap.groovy

This had to changed to be under a package name

grails-app
        init
             myapp
                 BootStrap.groovy

After this change the BootStrap.groovy file was executed on startup

Enter ngMocks ngMocks is a library for testing Angular Component dependencies. More information can be found here on it  https://github.com/ike18t/ng-mocks How do we use it? Firstly we need to import the library into our Jasmine test file. import { MockComponent } from 'ng-mocks'; Then we need to ...
