Can't run Maven grails app in IDEA: ClassNotFoundException: org.apache.catalina.startup.Tomcat

I have the Grails project that is managed and compiled by Maven. I'm trying to run application with IntelliJ IDEA 10.5.4. The project is imported into IDEA as Maven project.

When I try ro run or debug application I get an error:

Fatal error forking Grails JVM: java.lang.reflect.InvocationTargetException
java.lang.RuntimeException: java.lang.reflect.InvocationTargetException
    <...>
Caused by: java.lang.reflect.InvocationTargetException
    <...>
Caused by: java.lang.NoClassDefFoundError: org/apache/catalina/startup/Tomcat
    <...>
Caused by: java.lang.ClassNotFoundException: org.apache.catalina.startup.Tomcat
    <...>

I've already installed Tomcat 6 server into IDEA's settings, but I think this is not IDEA's problem but the Maven's one, because running mvn grails:run-app in console gives the same result. There is dependency build ":tomcat:$grailsVersion" in the file BuildConfig.groovy too if it's important.

What is wrong?

See this blog post for more information. The short version is to move the tomcat plugin out of BuildConfig and into your pom.xml

Also, make sure you have the line use pom inside your grails.project.dependency.resolution closure inside BuildConfig.
