此刻，在我的Eclipse IDE的“标记”选项卡中，出现此错误：

Description Resource    Path    Location    Type
Dynamic Web Module 3.0 requires Java 1.6 or newer.  example     line 1  Maven Java EE Configuration Problem
One or more constraints have not been satisfied.    example     line 1  Maven Java EE Configuration Problem

我尝试在项目的“构建”路径中（在Properties / Java Build Path中）修复此配置，但是当我运行“
Maven”>“更新项目”时，此选项的值返回到前一个。

我应该在哪里更改此选项以解决此错误？

Answer 1

1. 转到项目Build Path并将Java库版本更改为1.7

2. 转到Eclipse首选项-> Java->编译器->将合规性级别更改为 1.7

3. 右键单击项目->属性->项目构面

4. 取消选中Dynamic Web Module并单击“ 应用” （JavaServer Faces如果已选中，则也取消选中）
5. 将Java构面版本更改为1.7，然后单击“ 应用”
6. 添加Dyanmic Web Module v3.0，应用。

Eclipse的构面配置有问题。确保Apply在检查和取消检查构面之间保持击中状态。
