maven-compiler-plugin 版本错误解决方法

项目执行Maven build后出现WARNING提示。报如信息如下，根据报错信息猜测是maven-compiler-plugin的版本信息问题

[WARNING]  
[WARNING] Some problems were encountered while building the effective model for com.xxx.xxx:xxxx:jar:0.0.1-SNAPSHOT  
[WARNING] 'build.plugins.plugin.version' for org.apache.maven.plugins:maven-compiler-plugin is missing. @ line 16, column 12  
[WARNING]  
[WARNING] It is highly recommended to fix these problems because they threaten the stability of your build.  
[WARNING]  
[WARNING] For this reason, future Maven versions might no longer support building such malformed projects.  
[WARNING]

POM.xml中maven-compiler-plugin插件信息如下

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

修改POM.xml,增加maven-compiler-plugin插件版本信息，如下

<plugins>    
    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>  
        <version>2.3.2</version>  
        <configuration>    
            <source>1.6</source>    
            <target>1.6</target>    
        </configuration>    
    </plugin>    
</plugins>

Maven clean一下再编译时一切OK了~.~
