Tomcat启动报错[org.apache.struts2.dispatcher.Dispatcher]Dispatcher initialization failed

Tomcat启动报错：

[org.apache.struts2.dispatcher.Dispatcher]Dispatcher initialization failed

Unable to load configuration. - bean - jar:file:/E:/SoftwareDevelopment/Software/Eclipse4.3/eclipse-jee-kepler-SR1-win32-x86_64/Workspace/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/kytsoft-cms/WEB-INF/lib/struts2-core-2.3.14.jar!/struts-default.xml:29:72

原因：

jar包重复，Tomcat的lib下加了jar包，项目的lib中又加入一遍jar包，形成冲突！
