Grails Plugin Get Plugin's Root or Installed Directory

Question

I'm writing a plugin and I'm trying to write a file inside of the Plugin's root or installed directory (not sure what to refer to this to). I can't seem to figure out how to get a hold of this value. Doing System.properties['base.dir'] will result in the implementing Grails project's root directory. So right now I have two directories:

C:/PluginProject/

C:/GrailsAppThatUsesPlugin/

It's my understanding that when this becomes a distributed plugin a user will similarly have two directories:

GRAILS_HOME/grails-version/projects/projectName/plugins/myPlugin/

C:/GrailsAppThatUsesPlugin/

Inside of my plugin project I need to create a file. It needs to be inside of my plugin because the file I'm writing needs to reference other files that my plugin provides. The few things that I've tried that haven't worked are:

1. System.properties['base.dir']
2. new File("")
3. In a groovy script within a plugin you can simply refer to pluginNamePluginDir but I'm trying to access this from a POGO.
4. Looking at all of the System.properties none of them have the plugin directory
5. grailsApplication doesn't seem to contain this type of information either.

Any help is greatly appreciated.

This worked for me (both in-place and regular plug-ins):

import org.codehaus.groovy.grails.plugins.GrailsPluginUtils

GrailsPluginUtils.pluginInfos.find { it.name == pluginName }.pluginDir
