使用wagon-maven-plugin外掛程式自動部署項目

該外掛程式的maven依賴為：

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

外掛程式的文檔地址為：
http://www.mojohaus.org/wagon-maven-plugin/

主要提供如下幾個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：

為了讓wagon-maven-plugin外掛程式能SSH連上Linux伺服器，首先需要在Maven的設定檔settings.xml中配置好server的使用者名稱和密碼。

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

使用該外掛程式，需要在build裡面配置如下內容

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

如下示範了一個，使用該查詢部署一個war到tomcat的過程

<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>                  <!-- 需要部署的檔案 -->                  <fromFile>target/osc-shop.war</fromFile>                  <!-- 部署目錄 -->                  <url>scp://hadoop@192.168.1.222/home/hadoop/apache-tomcat-8.0.5/webapps/                  </url>                  <commands>                      <!-- 關閉tomcat -->                      <command>/home/hadoop/apache-tomcat-8.0.5/bin/shutdown.sh</command>                      <!-- 刪除之前解壓後的目錄 -->                      <command>rm -rf /home/hadoop/apache-tomcat-8.0.5/webapps/osc-shop                      </command>                      <!-- 啟動tomcat -->                      <command>/home/hadoop/apache-tomcat-8.0.5/bin/startup.sh</command>                  </commands>                  <displayCommandOutputs>true</displayCommandOutputs>              </configuration>          </plugin>      </plugins>  </build> 

配置完成後，執行命令
mvn clean package wagon:upload-single wagon:sshexec
即可部署到伺服器，並且重啟了tomcat
