maven 1.5 编译级别

   在pom.mxl中增加以下内容

      <build>
        <plugins>
            <plugin>
                <artifactId>maven-compiler-plugin</artifactId>
                <configuration>
                    <source>1.5</source>
                    <target>1.5</target>
                </configuration>
            </plugin>
        </plugins>
    </build>

西面是1.6的，另外加上了版本和编码

1. <plugin>  
2.     <groupId>org.apache.maven.plugins</groupId>  
3.     <artifactId>maven-compiler-plugin</artifactId>
