使用wagon-maven-plugin插件自动部署项目

该插件的maven依赖为：

<dependency>
	<groupId>org.codehaus.mojo</groupId>
	<artifactId>wagon-maven-plugin</artifactId>
	<version>1.0</version>
</dependency>

插件的文档地址为：

http://www.mojohaus.org/wagon-maven-plugin/

主要提供如下几个goal

• wagon:upload-single uploads the specified file to a remote location.
• wagon:upload uploads the specified set of files to a remote location.
• wagon:download-single downloads the specified file from a remote location.
• wagon:download downloads the specified set of files from a remote location.
• wagon:list lists the content of a specified location in a remote repository.
• wagon:copy copies a set of files under a Wagon repository to another.
• wagon:merge-maven-repos merges , including metadata, a Maven repository to another.
• wagon:sshexec Executes a set of commands at remote SSH host.

用法如下：

为了让wagon-maven-plugin插件能SSH连上Linux服务器，首先需要在Maven的配置文件settings.xml中配置好server的用户名和密码。

<server>
	<id>webserver</id>
	<username>hadoop</username>
	<password>123</password>
</server>

使用该插件，需要在build里面配置如下内容

<extensions>
	<extension>
		<groupId>org.apache.maven.wagon</groupId>
		<artifactId>wagon-ssh</artifactId>
		<version>2.10</version>
	</extension>
</extensions>

如下演示了一个，使用该查询部署一个war到tomcat的过程

<build>
	<finalName>osc-shop</finalName>
	<extensions>
		<extension>
			<groupId>org.apache.maven.wagon</groupId>
			<artifactId>wagon-ssh</artifactId>
			<version>2.10</version>
		</extension>
	</extensions>
	<plugins>
		<plugin>
			<groupId>org.codehaus.mojo</groupId>
			<artifactId>wagon-maven-plugin</artifactId>
			<version>1.0</version>
			<configuration>
				<serverId>webserver</serverId>
				<!-- 需要部署的文件 -->
				<fromFile>target/osc-shop.war</fromFile>
				<!-- 部署目录 -->
				<url>scp://[email protected]/home/hadoop/apache-tomcat-8.0.5/webapps/
				</url>
				<commands>
					<!-- 关闭tomcat -->
					<command>/home/hadoop/apache-tomcat-8.0.5/bin/shutdown.sh</command>
					<!-- 删除之前解压后的目录 -->
					<command>rm -rf /home/hadoop/apache-tomcat-8.0.5/webapps/osc-shop
					</command>
					<!-- 启动tomcat -->
					<command>/home/hadoop/apache-tomcat-8.0.5/bin/startup.sh</command>
				</commands>
				<displayCommandOutputs>true</displayCommandOutputs>
			</configuration>
		</plugin>
	</plugins>
</build>

配置完成后，执行命令

mvn clean package wagon:upload-single wagon:sshexec

即可部署到服务器，并且重启了tomcat
