Grails. Breakpoints in configuration code not working

I'm trying to debug a problem with some configuration code in Grails. I can set a breakpoint in "grails-app/conf/application.groovy", but when I run the code in the debugger, it doesn't stop at the breakpoint, even though it executes the surrounding code, as witnessed by output from println statements...

To be clear, there are two files called “application.groovy” - one is the Application class that contains “main” and the other is a Groovy version of the configuration file:

init/package/Application.groovy
conf/application.groovy

To reproduce my problem, create a Grails application, add a line that says
```
println “Hello world”
```
to the file “conf/application.groovy”, set a breakpoint on that line, and Debug the application.

Create a Grails application, add println “Hello world” to conf/application.groovy, set a breakpoint there, and debug the application. Compare the behavior with init/package/Application.groovy and trace how the debugger handles the configuration file; done means execution stops at the breakpoint in conf/application.groovy.
