[SOLVED] Grails 3 - Read classpath resource in Bootstrap.groovy

Grails 3 - Read classpath resource in Bootstrap.groovy

I'm migrating a Grails 2.5 application to Grails 3.0.9 and having some issue reading a classpath resource in grails-app/init/BootStrap.groovy.

In Grails 2.5.x it was possible to access resource (e.g. textfiles) using the Spring ClassPathResource when putting the resource file into the same folder as the BootStrap.groovy

def file1 = new ClassPathResource('my-textfile.txt').file

In Grails 3 it works when I start my application using grails run-app. All resources are taken from src/main/resources. But if I start the application using the Spring Boot Application (located at /grails-app/init/a/b/Application.groovy) class in IntelliJ the BootStrap.groovy find the resources anymore.

Does anyone know how to access these files within BootStrap.groovy in Grails 3.0.9 when starting the app using Application.groovy?

Solution

According to the Gradle convention I place the resources under src/main/resource since they need to be accessible at runtime.

For some reasons my grails-app/init/a/b/Application.groovy can't find these resources so I had to place a symbolic link to grails-app/init/a/b. After that everything works as expected.
