javaweb项目编译错误

Eclipse Maven 开发一个 jee 项目时，编译时遇到以下错误：
Description Resource Path Location Type
Dynamic Web Module 3.0 requires Java 1.6 or newer. bdp line 1 Maven Java EE Configuration Problem

Description Resource Path Location Type
One or more constraints have not been satisfied. bdp line 1 Maven Java EE Configuration Problem

 

解决方案：

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

　　

<build>  
    <plugins>  
        <!-- define the project compile level -->  
        <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>
