This is a Grails Plugin that enable the usage of Scala code in Grails Web projects.

Distribution for the plugin source distribution -- this is the recommended version, because the binary version of this plugin doesn't contain required jars


  • a Servlet container to run the Web application, as required by the used version of Grails
  • Scala (as specified in plugin descriptor) and related dependencies


In BuildConfig.groovy of the webapp, under the plugins section (at the end of the file) add:

compile ":scala:<version>"

then run grails refresh-dependencies, grails clean , then grails compile , and the plugin should be installed. In case of Errors during plugin installation, Set log level to 'warn' in BuildConfig.groovy to get more information, and retry. Instead of the compile it's possible even to use runtime, and in that case simply running a grails console should be enough.


See the Plugin documentation (sources under src/docs/), or the "live" version here: grails-scala docs

Home Page for the project (and sources) on GitHUB: grails-scala

Note that this plugin uses the utility jar groovytransforms, since 0.3 hosted at JCenter (BinTray): groovytransforms and that repository has been added manually in Plugin configuration (because the Plugin uses a legacy Grails release).
