The handling of JARs is kept pretty easy in grails. If you don't use stuff like maven you can just copy your JARs into the lib folder in the root directory of your grails application.
Try to put them there and see if it solves the problem.
Further: what IDE do you use? IntelliJ for instance recognize JARs within the lib folder instantly. So you should see the effects in your IDE already.
