Eclipse Maven 开发一个 jee 项目时，编译时遇到以下错误：  
DescriptionResourcePathLocationType  
Dynamic Web Module 3.0 requires Java 1.6 or newer. bdpline 1 Maven Java EE Configuration Problem  
  
DescriptionResourcePathLocationType  
One or more constraints have not been satisfied. bdpline 1 Maven Java EE Configuration Problem  
如图：  
![Dynamic Web Module 3.0 requires Java 1.6 or newer][]  
但是 Eclipse 明明已经将编译级别设置为 1.7：  
![Eclipse compiler][]  
这是由于你的 Maven 编译级别是 jdk1.5 或以下，而你导入了 jdk1.6 以上的依赖包：查看 Eclipse 的 Navigator 视图下该项目的 .classpath 文件：

**\[html\]**  [view plain][]   [copy][view plain]

[print][view plain] [?][view plain]

1.  **<****classpathentry** kind="con" path="org.eclipse.jdt.launching.JRE\_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/J2SE-1.5"**>**  
2.      **<****attributes****>**  
3.          **<****attribute** name="maven.pomderived" value="true"**/>**  
4.      **</****attributes****>**  
5.  **</****classpathentry****>**

解决办法 ：  
使用 maven-compiler-plugin 将 maven 编译级别改为 jdk1.6 以上：

**\[html\]**  [view plain][]   [copy][view plain]

[print][view plain] [?][view plain]

1.  **<****build****>**  
2.      **<****plugins****>**  
3.            
4.          **<****plugin****>**  
5.              **<****groupId****>**org.apache.maven.plugins**</****groupId****>**  
6.              **<****artifactId****>**maven-compiler-plugin**</****artifactId****>**  
7.              **<****version****>**2.3.2**</****version****>**  
8.              **<****configuration****>**  
9.                  **<****source****>**1.7**</****source****>**  
10.                 **<****target****>**1.7**</****target****>**  
11.             **</****configuration****>**  
12.         **</****plugin****>**  
13.     **</****plugins****>**  
14. **</****build****>**
