I am using Grails 1.2.1 and Groovy-Grails Tool Suite 3.1.0. Before that I was used 2.5.2.RELEASE of STS. But after upgrading to Groovy-Grails Tool Suite 3.1.0, when I am trying to run the app I am getting the following error:

Solution

In your console you can see:

For further info visit http://grails.org/Plugins

So, you should go to this page and try to find plugin functional test. On the page of this plugin functional test you can see

Dependency :

compile ":functional-test:2.0.RC1"

Custom repositories :

mavenRepo "http://repository.codehaus.org/"

mavenRepo "http://repository.jboss.org/maven2/"

So, try to add this repositories to the BuildConfig.groovy. And now current version of grails - 2.2 :)

If it is don't work, try to use last version of plugin: functional-test:2.0.RC1
