Since Grails 2.3, it is no longer possible to install plugins directly from the file sytem.
If you wish to use local plugins then run 'maven-install' in the plugin directory to install the plugin into your local Maven cache.
Then inside your application's grails-app/conf/BuildConfig.groovy file declare the dependency and it will be resolved from you Maven cache.
If you make a change to the plugin simply run 'maven-install' in the directory of the plugin project again and the change will be picked up by the application (if the plugin version ends with -SNAPSHOT)
