今天早上（南非时间），Maven下载了最新的primefaces jar（版本5.3）。虽然我的项目是以maven将项目部署到我的Web容器（在本例中为Wildfly 9.0.1.Final）的方式设置的，但由于以下异常导致部署失败：

我已经恢复到PrimeFaces 5.2，现在确实启动并运行应用程序。
我该如何解决这个问题？
我有完全相同的错误消息。问题是我的WAR中仍然存在旧的primefaces-5.2.jar（在我的情况下由Maven拉入）。清理整个项目后，问题就消失了。
因此，请确保项目或部署中某处没有隐藏旧版Primefaces。
您必须清除Wildfly上的日志，数据和tmp文件夹。此外，您必须在WEB-INF / lib文件夹中进行验证，并擦除与primefaces相关的所有库。最后，在项目的另一个时间运行Maven。
试试这个：在“服务器”选项卡中的eclipse中，右键单击Tomcat实例，然后单击“Clean Tomcat Work Directory ...”。
