Question

首先，我真的很抱歉我糟糕的英语。我开始研究Jboss和Ejb，我买了一本关于这个主题的书，我不想宣传这本书，但它是jboss as7development。我试图在第2,3,4和5章中进行练习，但我遇到了同样的问题。本书使用了maven Eclipse Jboss的组合。它使用javaee 6原型项目，并且在某一点上需要通过面转换项目生命周期，但Eclipse不允许它。我在互联网上搜索了这个问题，但我找不到任何解决方案。我尝试使用javaee7原型，但使用相同的pom.xml，但它不起作用。项目构面中的jsf web模块ecc版本是正确的，但Eclipse在以下标记中显示两个错误：

无法将项目构面动态Web模块的版本更改为2.3 ticket-agency-jpa line 1
Maven Java EE配置问题尚未满足一个或多个约束。 ticket-agency-jpa第1行Maven Java EE配置问题

我在这里发布了我的pom.xml：

对于我的项目，我正在使用eclipse开普勒，我需要使用jsf 2.1。 Web动态模块是3.0，这是正确的，当我尝试更改jsf版本时，eclipse说：无法将项目facet JavaServerFaces的版本更改为2.1。有关如何进行的任何建议吗？

Answer 1

这是Eclipse的方面机制的一个已知问题。

我recently answered another question exactly like this。

基本上，您必须在取消选择项目构面和更改其版本之间单击应用。

干杯。

如何在eclipse中更改JSF的版本？
