How deploy maven3 artifact to remote server using scp - linux

Question

I want to have my own maven repository for artifacts created by myself but I have a problem trying to make a deploy of maven 3 artifact to a custom server. To explain this better I'm going to give some information:
I'm using Maven 3
I'm using Eclipse Keppler
I'm using Jenkins
The remote server is running Ubuntu Server 11.04
Jenkins is running on the Ubuntu server
My local machine is running Windows XP
My first attempt was with my machine. I run Maven in Eclipse to make the deploy, and everything works fine. I add the following to my projects pom
<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>
And in my settings.xml I add
<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>
So in my local machine it works, but I need to get this work using Jenkins. I modified the Jenkins settings.xml, because it runs on Linux, so doesn't need sshExecutable. The Jenkins settings.xml looks like
<servers>
<server>
<id>my server id</id>
<username>server username</username>
<password>server password</password>
</server>
</servers>
Then I modified the pom.xml to execute just scp and not scpexe
<distributionManagement>
<repository>
<id>my server id</id>
<name>my repository name</name>
<url>scp://my server//path/to/my/repository</url>
</repository>
</distributionManagement>
But according to this page https://cwiki.apache.org/confluence/display/MAVEN/Maven+3.x+Compatibility+Notes maven 3 does not support scp. I run it any way and I got the following error message from Jenkins log
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 :
If I use scpexe instead of scp I got another error message
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 :
The only way I could make deploy, was doing it in two steps
Configuring Jenkins to make just the install goal
Running the following command from command line
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=my repository id
I tried many things, including writing that command into Jenkins goal, but everytime I use the scp command in Jenkins the build fails.
Any idea of how to solve this issue will be appreciated.

I am interested to see if there's any real Maven solutions to this. I have always fixed this using the Maven Antrun plugin as follows:
<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>
A few notes on this: I activate this profile with a combination of running to the deploy phase, and providing a deployment.server setting. For my convenience then, I add the corresponding settings to my settings.xml so that I don't have to provide these all on the command-line every time:
<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>
I skip the actual deploy goal because it will be executed when I run to the deploy phase, which I don't want.

The Verhagen's answer is correct but a more pure maven solution is this: https://stackoverflow.com/a/3303525/1881318
