Maven plugin external dependencies are not resolved

I am writing a maven plugin using Mojo classes. The plugin requires a dependency called jcifs and included it in the pom.xml of the plugin. I am able build the plugin and it is deployed into my local repository. I can find the jar file and pom.xml in my local repository.

When I use this plugin in another project in my local system, when executing the plugin goal, I am getting an exception saying the class not found. But the class is coming from the jcifs jar and it is included as part of the dependency for my plugin.

I am not able to figure out what I am missing here. Any help is appreciated

Following is the plugin pom.xml
