Grails: Cannot invoke method production() on null object

Here is my Config.groovy's environments section (using 2.3.6):

grails.app.context = "/"

environments {
    development {
        grails.logging.jul.usebridge = true
        grails.serverURL = "http://localhost:8080"
    } production {
        grails.logging.jul.usebridge = false
        grails.serverURL = "http://myapp.example.io"  // Although this isn't my production domain, it is a *.io TLD
    }
}

When I do a grails -Dgrails.env=development run-app I get:

| Error Error packaging application: Error loading Config.groovy: Cannot invoke method production() on null object (Use --stacktrace to see the full trace)

What's going on here?

Use production DSL in a new line. If used in the same line as the closure for development ends, then it is treated as a new method call on the return type of development call (which is void) with a closure param. The method name being production like:

development(clos1).production(clos2)

VERSUS

development(closure)
production(closure)

So use it as:

environments {
    development {
        grails.logging.jul.usebridge = true
        grails.serverURL = "http://localhost:8080"
    } 
    production {
        grails.logging.jul.usebridge = false
        grails.serverURL = "http://myapp.example.io"
    }
}

Also, you do not need to specify the environment as development for run-app, default environment is development, so just grails run-app should suffice.
