如何使用scp将maven3工件部署到远程服务器

Question

我想拥有自己创建的工件的maven存储库,但我在尝试将maven 3工件部署到自定义服务器时遇到问题.为了更好地解释这一点,我将提供一些信息:

• 我正在使用Maven 3
• 我正在使用Eclipse Keppler
• 我正在使用詹金斯
• 远程服务器正在运行Ubuntu Server 11.04
• Jenkins正在Ubuntu服务器上运行
• 我的本地计算机正在运行Windows XP

我的第一次尝试是用我的机器.我在Eclipse中运行Maven来进行部署,一切正常.我将以下内容添加到我的项目pom中

    <build>
           ...
        <extensions>
            <extension>
                <groupId>org.apache.maven.wagon</groupId>
                <artifactId>wagon-ssh-external</artifactId>
                <version>1.0-beta-6</version>
            </extension>
        </extensions>
          ...
      </build>

...

<distributionManagement>
      <repository>
          <id>my server id</id>
          <name>my repository name</name>
          <url>scpexe://my server//path/to/my/repository</url>
      </repository>
  </distributionManagement>

在我的settings.xml中,我添加了

<servers>  
      <server>  
          <id>my server id</id>  
         <username>server username</username>   
         <password>server password</password> 

         <configuration>
             <sshExecutable>plink</sshExecutable>
             <scpExecutable>pscp</scpExecutable>
         </configuration>  

     </server>  
 </servers>  

所以在我的本地机器上它可以工作,但我需要使用Jenkins来完成这项工作.我修改了Jenkins settings.xml,因为它在Linux上运行,所以不需要sshExecutable.Jenkins settings.xml看起来像

<servers>  
      <server>  
          <id>my server id</id>  
         <username>server username</username>   
         <password>server password</password> 

     </server>  
 </servers>  

然后我修改了pom.xml来执行scp而不是scpexe

<distributionManagement>
      <repository>
          <id>my server id</id>
          <name>my repository name</name>
          <url>scp://my server//path/to/my/repository</url>
      </repository>
  </distributionManagement>

但是根据这个页面https://cwiki.apache.org/confluence/display/MAVEN/Maven+3.x+Compatibility+Notes maven 3不支持scp.我以任何方式运行它,我从Jenkins日志中收到以下错误消息

mavenExecutionResult exceptions not empty
message : Failed to execute goal org.apache.maven.plugins:maven-deploy-plugin:2.7:deploy (default-deploy) on project myproject: Failed to deploy artifacts/metadata: No connector available to access repository my_repository (scp://my server//path/to/my/repository) of type default using the available factories WagonRepositoryConnectorFactory
cause : Failed to deploy artifacts/metadata: No connector available to access repository my_repository (scp://my server//path/to/my/repository) of type default using the available factories WagonRepositoryConnectorFactory
Stack trace : 

如果我使用scpexe而不是scp,我会收到另一条错误消息

mavenExecutionResult exceptions not empty
message : Failed to execute goal org.apache.maven.plugins:maven-deploy-plugin:2.7:deploy (default-deploy) on project pruebanueva: Failed to deploy artifacts: Could not transfer artifact {$groupId}:{$artifactId}:{$package}:{$version} from/to my_repository (scpexe://my server//path/to/my/repository): Error executing command for transfer
cause : Failed to deploy artifacts: Could not transfer artifact {$groupId}:{$artifactId}:{$package}:{$version} from/to my_repository (scpexe://my server//path/to/my/repository): Error executing command for transfer
Stack trace : 

我可以进行部署的唯一方法是分两步完成

1. 配置Jenkins以实现安装目标
2. 从命令行运行以下命令

mvn deploy:deploy-file -DgroupId = $ groupId -DartifactId = $ artifactId -Dversion = $ version -Dpackaging = jar -Dfile = path/to/file.jar -Durl = scp:// my server // path/to/my/repository -DrepositoryId =我的存储库ID

我尝试了很多东西,包括将该命令写入Jenkins目标,但每次我在Jenkins中使用scp命令时,构建都会失败.

任何想法如何解决这个问题将不胜感激.

我有兴趣看看是否有任何真正的Maven解决方案.我一直使用Maven Antrun插件修复此问题,如下所示:

<profile>
  <id>deploy</id>
  <activation>
    <property>
      <name>deployment.server</name>
    </property>
  </activation>
  <build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-antrun-plugin</artifactId>
        <version>1.7</version>
        <executions>
          <execution>
            <phase>deploy</phase>
            <goals>
              <goal>run</goal>
            </goals>
            <configuration>
              <target>
                <echo>deploying to server: ${deployment.server}</echo>
                <taskdef classname="org.apache.tools.ant.taskdefs.optional.ssh.Scp" name="scp" />
                <scp file="${project.build.directory}/${project.artifactId}.war" password="${deployment.password}" todir="${deployment.userName}@${deployment.server}:" trust="true" verbose="true" />
                <!-- <sshexec command="echo unity | sudo -S cp ${project.build.finalName}.jar $( if [ -e /station ]; then echo /station/lib; else echo /opt/pkg-station*/webapps/station*/WEB-INF/lib; fi )" host="${targetStation}" password="unity" trust="true" username="wps"></sshexec> -->
              </target>
            </configuration>
          </execution>
        </executions>
        <dependencies>
          <dependency>
            <groupId>com.jcraft</groupId>
            <artifactId>jsch</artifactId>
            <version>0.1.25</version>
          </dependency>
          <dependency>
            <groupId>org.apache.ant</groupId>
            <artifactId>ant-jsch</artifactId>
            <version>1.7.1</version>
          </dependency>
        </dependencies>
      </plugin>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-deploy-plugin</artifactId>
        <version>2.7</version>
        <configuration>
          <skip>true</skip>
        </configuration>
      </plugin>
    </plugins>
  </build>
</profile>

关于此的一些注意事项:我通过运行到deploy阶段并提供deployment.server设置来激活此配置文件.为方便起见,我将相应的设置添加到my中,settings.xml这样我就不必每次都在命令行上提供这些设置:

<profile>
    <id>alwaysActiveProfile</id>
    <properties>
        <deployment.server>10.10.10.10</deployment.server>
        <deployment.userName>userName<deployment.userName>
        <deployment.password>password</deployment.password>
    </properties>
</profile>

我skip是实际的deploy目标,因为它会在我跑到deploy阶段时被执行,这是我不想要的.
