这几天，了解和学习Apache Mina，使用Maven管理项目，可是生成项目时，一直报一个异常，查了很多资料，尝试了很多办法，就是木有解决，开始以为自己钻了牛角尖，将此问题放置几天，再来看，今天再次看，还是同样的问题，不过最后还是给解决了，记录下吧，算是一个教训。

在使用Maven管理mina的包时，由于mina打包为bundle，此包为OSGI使用，OSGI的各个模块叫做bundle，OSGI，以前在公司使用过，做过一个项目，木有深入的了解，在管理mina的依赖时，首先生成项目的命令，运行此命令时，就出错了

D:\GitHub\java>mvn install eclipse:eclipse -Dwtpversion=2.0 -DdownloadSources=true

异常如下：

[ERROR] Failed to execute goal on project java: Could not resolve dependencies f

解决办法

在项目中的pom.xml文件中增加一个插件，配置如下：

<plugin>
	    			<groupId>org.apache.felix</groupId>
	   			<artifactId>maven-bundle-plugin</artifactId>
	   			<extensions>true</extensions>
			</plugin>

加上此配置，再运行命令，就可创建成功了！
