“JavaServer Faces2.2需要动态Web模块2.5或更高版本。”

Question

我使用Eclipse for Java EE和AWS Toolkit for Eclipse v2。我在macOS Mojave 10.14.5版上。我已经安装了Java8。

当我第一次创建一个AWS Java Web项目时，我会遇到这样的错误：“JavaServer Faces2.2不能安装：一个或多个约束没有得到满足。”和“JavaServer Faces2.2需要动态Web模块2.5或更高版本。”如这张截图所示：

Answer 1

也许有人会有用。

如果您使用的是JBoss工具，那么不要为项目设置JSF方面

Properties -> Project Facets -> JavaServer Faces (2.3)

最好使用另一个选项：

Properties -> JBoss Tools Knowledge Base -> JBoss Tools Knowledge Base Support
