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 1Maven Java EE Configuration Problem
DescriptionResourcePathLocationType
One or more constraints have not been satisfied.bdpline 1Maven Java EE Configuration Problem
如图:
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?
- <classpathentry?kind="con"?path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/J2SE-1.5">??
- ????<attributes>??
- ????????<attribute?name="maven.pomderived"?value="true"/>??
- ????</attributes>??
- </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?
- <build>??
- ????<plugins>??
- ??????????
- ????????<plugin>??
- ????????????<groupId>org.apache.maven.plugins</groupId>??
- ????????????<artifactId>maven-compiler-plugin</artifactId>??
- ????????????<version>2.3.2</version>??
- ????????????<configuration>??
- ????????????????<source>1.7</source>??
- ????????????????<target>1.7</target>??
- ????????????</configuration>??
- ????????</plugin>??
- ????</plugins>??
- </build>??
