Maven dependencies are for building project. Maven Jar Plugin is not using it when JAR id packaged. So you cant run without additional work.
Hovewer there are many solution for this. For example you can use Maven One Jar Plugin and package all dependencies into JAR - but this is not always usable
http://onejar-maven-plugin.googlecode.com/svn/mavensite/usage.html
You can create archive with jar-dependencies
http://maven.apache.org/plugins/maven-assembly-plugin/descriptor-refs.html#jar-with-dependencies
You can merge all jars into one with Maven Shade Plugin
