This morning (South African time), Maven downloaded the latest primefaces jar (version 5.3). While my project is setup in a manner that maven deploys the project to my Web Container (in this case, Wildfly 9.0.1.Final), it failed deployment due to the following exception:

I have reverted back to PrimeFaces 5.2 for now do get the application up and running.
How do I resolve this problem?
回答1:
I had the exact same error message. The problem was that there still was the old primefaces-5.2.jar in my WAR (pulled in by Maven in my case). After cleaning the whole project the problem was gone.
So make sure that there is no older version of Primefaces hidden somewhere in your project or deployment.
回答2:
You must clean the logs, data and tmp folders on Wildfly. Additionally, you must verify in your WEB-INF/lib folder and erase all the libraries related to primefaces. Finally, run other time the Maven on the project.
回答3:
Try this: in eclipse in "servers" tab right-click on the Tomcat instance and click on "Clean Tomcat Work Directory ...".
