Eclipse Maven 开发一个 jee 项目时,编译时遇到以下错误

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:

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