From grails project, we can know which grails version used .Like that can i get groovy version?
You can look in the install directory under lib. For example in Grails 2.2.3 it's lib/org.codehaus.groovy/groovy-all/jars/groovy-all-2.0.8.jar
so the version is 2.0.8.
If you want to find the value programmatically at runtime, call GroovySystem.getVersion()
to get the current version string.
