Missing class while executing maven-soapui-plugin

I am a noob =) in Maven and I am trying to run SoapUI tests using maven-soapui-plugin. When I run error occurs in console:

[ERROR] Failed to execute goal eviware:maven-soapui-plugin:4.5.0:test (soapUI) on projectMyProject: Execution soapUI of goal eviware:maven-soapui-plugin:4.5.0:test failed: A required class was missing while executing eviware:maven-soapui-plugin:4.5.0:test: org/fife/ui/rtextarea/RTextArea

I’ve found that this error connected somehow with pom.xml file of the maven-soapui-plugin (http://ift.tt/1DJRN79). Has anyone faced with similar problem and how to solve it? My pom.xml is here: http://ift.tt/1D65ufv Thank you very much for your help.
