‘ComposedConfig’ is exactly how you have specified.

I think I have copied your approach pretty faithfully, but get the following exception. My config files are below

groovy.lang.MissingPropertyException: No such property: grails for class: TudgrailsConfig
at TudgrailsConfig.run(TudgrailsConfig.groovy:9)

grails-app/config wouldn’t be in your classpath.

Also, did you try the ComposedConfigScript that I have at the end of the post? I can’t quite be sure from your message, but I think you might be trying the example above that I say would be nice, but doesn’t actually work.

Then in Config.groovy:

def configSupport = new ConfigSlurper().parse( ConfigSupport )
assert configSupport != null

grails.config = grails.config.merge(configSupport)
//ConfigurationHolder.setConfig(configSupport)

The config I am pulling in is .\grails-app\utils\com\comcast\uivr\divr\util
PromptProperties.groovy:

prompt{
prompt_test_cfg = “test”
}

//assert grails.config.application.configuration.version == “3.0.1″
assert configSupport.prompt.prompt_test_cfg == “test”

I even tried moving ConfigSupport into .\grails-app\utils\com\comcast\uivr\divr\util as well but I can not get it to work

The thing that actually made me want to do this in the first place was the acegi/spring security plugin.

We have 5 apps currently that all share very similar spring security settings but we wanted the ability to vary a couple of the property without doing a copy/paste of the entire config file.

This solution lets us do this, we includeConfig on the default config that’s in a shared config file used across all projects. Then tweak the config file for the places that differ slightly.
