/**
 * Publishes project artifacts to a maven repository by performing a maven
 * deploy. The repository url and additional configuration must be performed
 * in-code. The following options are supported:
 * 
 * -artifact: the name of the artifact to be published. The artifacts
 * directory is checked for classes, source and javadoc containing artifacts
 * that match the name. If this option isn't specified then all discovered
 * artifacts are published.
 * -user: used if the publish command has been configured for a remote
 * protocol such as scp.
 * -key: the path to the private key for scp key-based authentication. If
 * not specified then the default key location is used if it exists.
 * -password: the password for scp transport if specified.
 * -passphrase: the passphrase for scp key-based authentication. Can be left
 * out if there is no passphrase for the given key.
 * 
 * 
 * Example: publish Example: "publish -user bob" Example:
 * "publish -user bob -key ~/.ssh/myprivatekey"
