Maven 3: SSH deployment to foreign repository

Using the maven-deploy-plugin to deploy artifacts to a repository that is not the original target repository of a project is getting complicated with Maven 3 when the wagon SSH provider is not part of the Maven distribution. The following JAR files must be added to the Maven distribution into the lib/ext extension folder:

• jsch-0.1.44-1.jar
• plexus-utils-3.0.jar
• plexus-interactivity-api-1.0-alpha-6.jar
• wagon-ssh-2.2.jar\n* wagon-ssh-external-2.2.jar
• wagon-ssh-common-2.2.jar

Then the parent pom.xml of the project must be extended by the  following lines:

    <dependecy>
        <groupid>org.apache.maven.plugins</groupid>
        <artifactid>maven-deploy-plugin</artifactid>
    </dependecy>
    <dependecy>
        <groupid>org.apache.maven.wagon</groupid>
        <artifactid>wagon-ssh</artifactid>                
        <version>2.2</version>
    </dependecy>

The settings.xml contains the user credentials and looks like this:   

        <servers>      
            <server><id>myrepo-snapshots</id>         
                 <username>username</username>          
                 <privatekey>${user.home}/.ssh/id_rsa</privatekey>         
                <passphrase>key-passphrase</passphrase>          
                <filepermissions>666</filepermissions>          
                <directorypermissions>777</directorypermissions>
            </server> 
        </servers>  

Then the deploy phase can be executed like this:

mvn deploy -DaltDeploymentRepository=myrepo-snapshots::default::scp://host:port/var/www/repos/maven2-snapshot/
