You simply have multiple version of the Struts2 library in your project.

Remove all the further versions except the one you want to use, and you will be fine.

OTHER TIPS

It's possible your WEB-INF\classes folder contains a struts.xml and eclipse is loading its struts.xml twice, after your clasess\struts.xml is loaded. Try cleaning your classes folder, or at least remove the struts.xml file that is there.
