wildfly8.1上eclipse中的JSF2.2

我有一个从一些maven原型创建的项目，不记得是哪一个。我使用maven和Eclipse开普勒

该项目部署在Wildfly8.1服务器上

在facests项目中，我有JSF2.0，当我尝试将facet更改为JSF2.2时，我得到了massege Cann not change版本的facet JavaServerFaces

我是否必须更改maven pom文件中的某些内容

这是我的maven pom：

您没有提到您使用的Eclipse插件。假设您拥有当前版本的JBoss工具，那么在首次将Maven项目导入Eclipse时，应根据POM依赖项正确设置facet

在POM中，Java EE 6和7的依赖性混合在一起，这可能是问题的根源

尝试删除javax:javaeeapi:6.0依赖项—在POM中有独立的JavaEE7API—然后在Eclipse中运行Maven | Update项目

如果没有帮助，请从工作区中删除项目，从文件system.project.classpath中删除所有Eclipse元数据，。设置并重新导入项目。
