maven3 deploy执行报错

在maven2下面编译运行非常正常的项目，到了maven3下面做release:deploy的时候报如下错误：

[INFO] [INFO] ------------------------------------------------------------------------
[INFO] [ERROR] Failed to execute goal org.apache.maven.plugins:maven-deploy-plugin:2.7:deploy (default-deploy) on project xxx: Failed to deploy artifacts/metadata: No connector available to access repository my_repository (scp://[e-mail]/home/maven/repo) of type default using the available factories WagonRepositoryConnectorFactory -> [Help 1]
[INFO] [ERROR] 

原来在maven3里面，必须加载适当的extension 才能完成deploy.

 

我的distribution repository定义如下：

<distributionManagement>
		<repository>
			<id>my_repository</id>
			<name>Repository</name>
			<url>scp://[e-mail]/home/maven/repo</url>
		</repository>
	</distributionManagement>

 我使用了scp的部署方式，那么就应当增加如下的配置：

		</plugins>
		<extensions>
			<extension>
				<groupId>org.apache.maven.wagon</groupId>
				<artifactId>wagon-ssh</artifactId>
				<version>2.4</version>
			</extension>
		</extensions>
	</build>
