maven warnning 'build.plugins.plugin.version' is missing

裝完maven后，package或clean时出错：
[WARN]
[WARN] Some problems were encountered while building the effective model 
 [WARN] 'build.plugins.plugin.version' is missing fororg.apache.maven.plugins:maven.compiler.plugin
It is highly recommended to fix these problems because they threaten the stability of your build.
For this reason, future Maven versions might no longer support building such malformed projects.

org.apache.maven.plugins:maven.compiler.plugin是一个plugin。可以通过“Add Denpendency”来添加。

在pom.xml中添加新的dependency:

 <dependency>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>2.1</version>
<type>maven-plugin</type>
</dependency>
在build中添加：
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven.compiler.plugin</artifactId>
<configuration>
<source>1.5</source>
<target>1.5</target>
<verbal>true</verbal>
</configuration>
</plugin>
</plugins>
</build>
</project>

但是仍然有个错误，错误信息：build.plugins.plugin.version
可以看到，在pom.xml里面的<build>下面，沒有<version>。因此要多加一个version：
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven.compiler.plugin</artifactId>
<version>2.1</version>
<configuration>
<source>1.5</source>
<target>1.5</target>
<verbal>true</verbal>
</configuration>
</plugin>
</plugins>
</build>
</project>

好，解决问题。
