| <h2><a name="scp">SCP</a></h2> |
| <h3>Description</h3> |
| |
| <p><em>since Ant 1.6</em></p> |
| |
| <p>Copies a file or FileSet to or from a (remote) machine running an SSH daemon. |
| FileSet <i>only</i> works for copying files from the local machine to a |
| remote machine.</p> |
| |
| <p><b>Note:</b> This task depends on external libraries not included |
| in the Ant distribution. See <a |
| href="../install.html#librarydependencies">Library Dependencies</a> |
| for more information. This task has been tested with jsch-0.1.2 and later.</p> |

| <h3>Parameters specified as nested elements</h3> |
| |
| <h4>fileset</h4> |
| <p><a href="../CoreTypes/fileset.html">FileSet</a>s are used to select |
| sets of files to copy. |
| To use a fileset, the <code>todir</code> attribute must be set.</p> |
| |
| <h3>Examples</h3> |
| <p><b>Copy a single local file to a remote machine</b></p> |
| <pre> |
| <scp file="myfile.txt" todir="user:password@somehost:/home/chuck"/> |
| </pre> |
| |
| <p><b>Copy a single local file to a remote machine with separate |
| password attribute</b></p> |
| <pre> |
| <scp file="myfile.txt" todir="user@somehost:/home/chuck" password="password"/> |
| </pre> |
| |
| <p><b>Copy a single local file to a remote machine using key base |
| authentication.</b></p> |
| <pre> |
| <scp file="myfile.txt" |
| todir="user@somehost:/home/chuck" |
| keyfile="${user.home}/.ssh/id_dsa" |
| passphrase="my extremely secret passphrase" |
| /> |
| </pre> |
| |
| <p><b>Copy a single remote file to a local directory</b></p> |
| <pre> |
| <scp file="user:password@somehost:/home/chuck/myfile.txt" todir="../some/other/dir"/> |
| </pre> |
| |
| <p><b>Copy a remote directory to a local directory</b></p> |
| <pre> |
| <scp file="user:password@somehost:/home/chuck/*" todir="/home/sara"/> |
| </pre> |
| |
| <p><b>Copy a local directory to a remote directory</b></p> |
| <pre> |
| <scp todir="user:password@somehost:/home/chuck/"> |
| <fileset dir="src_dir"/> |
| </scp> |
| </pre> |
| <p><b>Copy a set of files to a directory</b></p> |
| <pre> |
| <scp todir="user:password@somehost:/home/chuck"> |
| <fileset dir="src_dir"> |
| <include name="**/*.java"/> |
| </fileset> |
| </scp> |
| |
| <scp todir="user:password@somehost:/home/chuck"> |
| <fileset dir="src_dir" excludes="**/*.java"/> |
| </scp> |
| </pre> |
| |
| <p><strong>Security Note:</strong> Hard coding passwords and/or usernames |
| in scp task can be a serious security hole. Consider using variable |
| substitution and include the password on the command line. For example: |
| <p> |
| <pre> |
| <scp todir="${username}:${password}@host:/dir" ...> |
| </pre> |
| Invoking ant with the following command line: |
| <pre> |
| ant -Dusername=me -Dpassword=mypassword target1 target2 |
| </pre> |
| |
| Is slightly better, but the username/password is exposed to all users on an Unix |
| system (via the ps command). The best approach is to use the |
| <code><input></code> task and/or retrieve the password from a (secured) |
| .properties file. |
| |
| <p> |
| |
| <p><strong>Unix Note:</strong> File permissions are not retained when files |
| are copied; they end up with the default <code>UMASK</code> permissions |
| instead. This is caused by the lack of any means to query or set file |
| permissions in the current Java runtimes. If you need a permission- |
| preserving copy function, use <code><exec executable="scp" ... ></code> |
| instead. |
