SCP

Description

since Ant 1.6

Copies a file or FileSet to or from a remote machine running SSH daemon. FileSet only works for copying files from the local machine to a remote machine.

Note: This task depends on external libraries not included in the Ant distribution. See Library Dependencies for more information. This task has been tested with jsch-0.1.2 to jsch-0.1.14.

Parameters

Attribute Description Required
file The file to copy. This can be a local path or a remote path of the form user[:password]@host:/directory/path. :password can be omitted if you use key based authentication or specify the password attribute. The way remote path is recognized is whether it contains @ character or not. This will not work if your localPath contains @ character. Yes, unless a nested <fileset> element is used.
localFile This is an alternative to the file attribute. But this must always point to a local file. The reason this was added was that when you give file attribute it is treated as remote if it contains @ character. This character can exist also in local paths. since Ant 1.6.2 Alternative to file attribute.
remoteFile This is an alternative to the file attribute. But this must always point to a remote file. since Ant 1.6.2 Alternative to file attribute.
todir The directory to copy to. This can be a local path or a remote path of the form user[:password]@host:/directory/path. :password can be omitted if you use key based authentication or specify the password attribute. The way remote path is recognized is whether it contains @ character or not. This will not work if your localPath contains @ character. Yes
localTodir This is an alternative to the todir attribute. But this must always point to a local directory. The reason this was added was that when you give todir attribute it is treated as remote if it contains @ character. This character can exist also in local paths. since Ant 1.6.2 Alternative to todir attribute.
localTofile Changes the file name to the given name while receiving it, only useful if receiving a single file. since Ant 1.6.2 Alternative to todir attribute.
remoteTodir This is an alternative to the todir attribute. But this must always point to a remote directory. since Ant 1.6.2 Alternative to todir attribute.
remoteTofile Changes the file name to the given name while sending it, only useful if sending a single file. since Ant 1.6.2 Alternative to todir attribute.
port The port to connect to on the remote host. No, defaults to 22.
trust This trusts all unknown hosts if set to yes/true.
Note If you set this to false (the default), the host you connect to must be listed in your knownhosts file, this also implies that the file exists.
No, defaults to No.
knownhosts This sets the known hosts file to use to validate the identity of the remote host. This must be a SSH2 format file. SSH1 format is not supported. No, defaults to ${user.home}/.ssh/known_hosts.
failonerror Whether to halt the build if the transfer fails. No; defaults to true.
password The password. Not if you are using key based authentication or the password has been given in the file or todir attribute.
keyfile Location of the file holding the private key. Yes, if you are using key based authentication.
passphrase Passphrase for your private key. Yes, if you are using key based authentication.
verbose Determines whether SCP outputs verbosely to the user. Currently this means outputting dots/stars showing the progress of a file transfer. since Ant 1.6.2 No; defaults to false.

Parameters specified as nested elements

fileset

FileSets are used to select sets of files to copy. To use a fileset, the todir attribute must be set.

Examples

Copy a single local file to a remote machine

  <scp file="myfile.txt" todir="user:password@somehost:/home/chuck"/>

Copy a single local file to a remote machine with separate password attribute

  <scp file="myfile.txt" todir="user@somehost:/home/chuck" 
  password="password"/>

Copy a single local file to a remote machine using key base authentication.

  <scp file="myfile.txt"
       todir="user@somehost:/home/chuck" 
       keyfile="${user.home}/.ssh/id_dsa"
       passphrase="my extremely secret passphrase"

  />

Copy a single remote file to a local directory

  <scp file="user:password@somehost:/home/chuck/myfile.txt" 
  todir="../some/other/dir"/>

Copy a remote directory to a local directory

  <scp file="user:password@somehost:/home/chuck/*" 
  todir="/home/sara"/>

Copy a local directory to a remote directory


  <scp todir="user:password@somehost:/home/chuck/">
    <fileset dir="src_dir"/>
  </scp>

Copy a set of files to a directory

  <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>

Security Note: 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:

    <scp todir="${username}:${password}@host:/dir" ...>
Invoke ant with the following command line:
    ant -Dusername=me -Dpassword=mypassword target1 target2

Unix Note: File permissions are not retained when files are copied; they end up with the default UMASK 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 <exec executable="scp" ... > instead.
