[SOLVED] Programmatically detecting if an external config file has been read in?

Programmatically detecting if an external config file has been read in?

We use grails.config.locations to pull in (optional) settings from a file external to the app. Is there a good way to detect that this file was loaded, either in Bootstrap.groovy or within Config.groovy itself?

Config.groovy has this:

grails.config.locations = [
  "file:${userHome}/.grails/${appName}-config.groovy"
]

It'd be nice to know if Grails found and read in this file.

Solution

You may be seeing this when turning Grails debug mode, but you don't want to do that. I am using the following strategy. First I check if the file exists:

 def externalConfigFile = "${userHome}/.grails/${appName}-config.groovy"
 if (new File(externalConfigFile).exists()) {
     grails.config.locations << "file:" + externalConfigFile
     log.info "External configuration file found at ${externalConfigFile} ..." 
 }

And then in the file itself I just log that it was run:

 log.info 'External config file was loaded.'

So now I can see in the logs upon startup that I found an external configuration file, it is an existing file, and the file was run by Grails, so it is loaded.

I haven't found anything better as yet.
