Unable to load bean using Struts convention plugin

I want to use annotation based config instead of xml based. Struts has convention plugin to do this kind of thing.

So I removed struts.xml file in main/resources, added this plugin as dependency, put some annotations on actions and tried to run my project on a server (Tomcat 7).

When the server starts, I get the next stacktrace:

Unable to load configuration. - bean - jar:file:/D:/EclipseWorkspace/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/shop/WEB-INF/lib/struts2-convention-plugin-2.3.24.jar!/struts-plugin.xml:32:155

The thing is that struts has xwork-core as dependency, so it lies in classpath, but somehow tomcat can't find it. These are my dependencies from pom.xml:

There are 2 points wrong in the pom.xml
1. struts2-core has already included xwork-core
2. version of struts2-core should be greater than/equal to version of structs2-convention-plugin

If you look into maven dependencies the struts2-core already has a dependency on xwork-core, so it should be downloaded when you build the app. Diffrent versions of plug-ins could make the plugin stop working or it just breaks on startup. You should use the following artifacts

<dependency>
    <groupId>org.apache.struts</groupId>
    <artifactId>struts2-core</artifactId>
    <version>2.3.24</version>
</dependency>
<dependency>
    <groupId>org.apache.struts</groupId>
    <artifactId>struts2-convention-plugin</artifactId>
    <version>2.3.24</version>
</dependency>
