How to use grails.plugin.location?

grails.plugin.location is not a dependency resolution, so it goes outside grails.project.dependency.resolution.

It should be like below, if both myPluginDemo and myPlugin are in the same directory. Moreover, this will not install the plugin into the app, but the application will refer to the file system for the plugin which is convenient in development mode. In order to use the packaged plugin it has to be referred in plugins inside grails.project.dependency.resolution

grails.plugin.location.myPlugin = "../myPlugin"
grails.project.dependency.resolution = {
    repositories {

    }
    dependencies {

    }
    plugins {

    }
}
