mvn compile时 warning maven-compiler-plugin is missing

pom文件出错代码

  <build>
	<plugins>
	  <plugin>
		<artifactId>maven-compiler-plugin</artifactId>
		<configuration>
			<source>1.6</source>
			<target>1.6</target>
		</configuration>
	   </plugin>
	</plugins>
  </build>

警告原因是maven3以上需要知道maven-compiler-plugin的版本号

解决方法加入版本号 代码如下

  <build>
	<plugins>
	  <plugin>
		<artifactId>maven-compiler-plugin</artifactId>
		<version>2.3.2</version>
		<configuration>
			<source>1.6</source>
			<target>1.6</target>
		</configuration>
	   </plugin>
	</plugins>
  </build>

编译通过
