In grails application you can add jar dependencies by just pasting the .jar file to lib folder. If your code doesn't find the jar dependency at runtime then you can do following :

Run the following grail command (s):

• clean

In eclipse you can open the Grails Command Prompt by :
Right Click on project -> Grail Tools -> Open Grails Command Prompt
