This plugin enables you to publish application WAR files and plugin packages (zip files) to Maven-compatible repositories. It can also install them to your local Maven cache.
Add this dependency to BuildConfig.groovy:
build ":release:<pluginVersion>"
where is the version of the plugin you want to use.
The plugin provides four commands:
grails generate-pom
grails maven-install
grails maven-deploy
grails publish-plugin
The first of these simply generates a pom.xml for your project's artifact, be it an application WAR or a packaged plugin. The second command installs the artifact into the local Maven cache. The third one deploys the package to a remote Maven-compatible repository. The last command will publish a plugin to the Grails central plugin repository or another repository of your choice. The publication process includes notification of a "plugin portal" (such as http://grails.org/plugins/) that the plugin has been released.
