方式1、修改maven全局jdk

修改 安装目录maven2confsettings.xml

<profiles>     
      <profile>       
           <id>jdk-1.6</id>       
           <activation>       
               <activeByDefault>true</activeByDefault>       
               <jdk>1.6</jdk>       
           </activation>       
           <properties>       
               <maven.compiler.source>1.6</maven.compiler.source>       
               <maven.compiler.target>1.6</maven.compiler.target>       
               <maven.compiler.compilerVersion>1.6</maven.compiler.compilerVersion>       
           </properties>       
   </profile>      
</profiles>    

方式2、修改项目pom.xml

<build>  
    <plugins>  
        <plugin>  
            <groupId>org.apache.maven.plugins</groupId>  
            <artifactId>maven-compiler-plugin</artifactId>  
            <version>2.0.2</version>  
            <configuration>  
                <source>1.6</source>  
                <target>1.6</target>  
            </configuration>  
        </plugin>  
    </plugins>  
</build>
