ClassNotFound Exception while trying Roo Standalone Sample generated, required, trying, error, while

Hi All,

I am a newbie in Roo and trying out the First Project (Roo Standalone) as mentioned in roo/start

STS Version : 2.3.3.M1-e3.5.2 Win32
ROO Version : 1.1.0.M1 [rev 3a0b8a3]
Maven Version : 2.2.1

All the Roo commands execute successfully and my workspace does not have any error and all GWT UI code get generated fine.

But as soon as I fire 'mvn gwt:run', I get the ClassNotFoundException : A required class is missing: org/codehaus/plexus/util/xml/XmlStreamReader
org.codehaus.plexus.util.xml.XmlStreamReader

Even after adding the following in pom.xml
--- 'lt;dependencygt;
lt;groupIdgt;org.codehaus.plexuslt;/groupIdgt;
lt;artifactIdgt;plexus-utilslt;/artifactIdgt;
lt;versiongt;1.5.15lt;/versiongt;   lt;/dependencygt; '

--- I still get the [ERROR] BUILD ERROR
-----------------------------------------------------
[INFO] Internal error in the plugin manager executing goal 'org.codehaus.mojo:gw
t-maven-plugin:1.3.1.google:run': Unable to load the mojo 'org.codehaus.mojo:gwt
-maven-plugin:1.3.1.google:run' in the plugin 'org.codehaus.mojo:gwt-maven-plugi
n'. A required class is missing: org/codehaus/plexus/util/xml/XmlStreamReader

Any insight into the matter will be very helpful.
