Vaadin with Grails dependency error

I have created my web application in grails and added the Vaadin dependency in Buildconfig.groovy. On running the app using grails run-app, i could not proceed due to the following errors.

| Configuring classpath | Error Failed to resolve dependencies (Set log level to ‘warn’ in BuildConfig.groovy for more information): - org.eclipse.jetty.orbit:javax.transaction:1.1.1.v201105210645 - org.eclipse.jetty.orbit:javax.servlet:3.0.0.v201112011016 - org.eclipse.jetty.orbit:javax.mail.glassfish:1.4.1.v201005082020 - org.eclipse.jetty.orbit:javax.activation:1.1.0.v201105071233 - org.eclipse.jetty.orbit:javax.annotation:1.1.0.v201108011116 - org.eclipse.jetty.orbit:org.objectweb.asm:3.1.0.v200803061910

I am using Intellij Idea IDE and Grails version 2.4. Any help is appreciated. Thank you.
