public class FTP
extends Task
Basic FTP client. Performs the following actions:
  • send - send files to a remote server. This is the default action.
  • get - retrieve files from a remote server.
  • del - delete files from a remote server.
  • list - create a file listing.
  • chmod - change unix file permissions.
  • rmdir - remove directories, if empty, from a remote server.
Note: Some FTP servers - notably the Solaris server - seem to hold data ports open after a "retr" operation, allowing them to timeout instead of shutting them down cleanly. This happens in active or passive mode, and the ports will remain open even after ending the FTP session. FTP "send" operations seem to close ports immediately. This behavior may cause problems on some systems when downloading large sets of files.
Since:
Ant 1.3

      protected void sendFile​(org.apache.commons.net.ftp.FTPClient ftp, java.lang.String dir, java.lang.String filename) throws java.io.IOException, BuildException
      Sends a single file to the remote host. filename may contain a relative path specification. When this is the case, sendFile will attempt to create any necessary parent directories before sending the file. The file will then be sent using the entire relative path spec - no attempt is made to change directories. It is anticipated that this may eventually cause problems with some FTP servers, but it simplifies the coding.
      Parameters:
      ftp - ftp client
      dir - base directory of the file to be sent (local)
      filename - relative path of the file to be send locally relative to dir remotely relative to the remotedir attribute
      Throws:
      java.io.IOException - in unknown circumstances
      BuildException - in unknown circumstances
    • delFile

      protected void delFile​(org.apache.commons.net.ftp.FTPClient ftp, java.lang.String filename) throws java.io.IOException, BuildException
      Delete a file from the remote host.
      Parameters:
      ftp - ftp client
      filename - file to delete
      Throws:
      java.io.IOException - in unknown circumstances
      BuildException - if skipFailedTransfers is set to false and the deletion could not be done
    • rmDir

      protected void rmDir​(org.apache.commons.net.ftp.FTPClient ftp, java.lang.String dirname) throws java.io.IOException, BuildException
      Delete a directory, if empty, from the remote host.
      Parameters:
      ftp - ftp client
      dirname - directory to delete
      Throws:
      java.io.IOException - in unknown circumstances
      BuildException - if skipFailedTransfers is set to false and the deletion could not be done
    • getFile

      protected void getFile​(org.apache.commons.net.ftp.FTPClient ftp, java.lang.String dir, java.lang.String filename) throws java.io.IOException, BuildException
      Retrieve a single file from the remote host. filename may contain a relative path specification.

      The file will then be retrieved using the entire relative path spec - no attempt is made to change directories. It is anticipated that this may eventually cause problems with some FTP servers, but it simplifies the coding.

      Parameters:
      ftp - the ftp client
      dir - local base directory to which the file should go back
      filename - relative path of the file based upon the ftp remote directory and/or the local base directory (dir)
      Throws:
      java.io.IOException - in unknown circumstances
      BuildException - if skipFailedTransfers is false and the file cannot be retrieved.
    • listFile

      protected void listFile​(org.apache.commons.net.ftp.FTPClient ftp, java.io.BufferedWriter bw, java.lang.String filename) throws java.io.IOException, BuildException
      List information about a single file from the remote host. filename may contain a relative path specification.

      The file listing will then be retrieved using the entire relative path spec - no attempt is made to change directories. It is anticipated that this may eventually cause problems with some FTP servers, but it simplifies the coding.

      Parameters:
      ftp - ftp client
      bw - buffered writer
      filename - the directory one wants to list
      Throws:
      java.io.IOException - in unknown circumstances
      BuildException - in unknown circumstances
    • makeRemoteDir

      protected void makeRemoteDir​(org.apache.commons.net.ftp.FTPClient ftp, java.lang.String dir) throws java.io.IOException, BuildException
      Create the specified directory on the remote host.
      Parameters:
      ftp - The FTP client connection
      dir - The directory to create (format must be correct for host type)
      Throws:
      java.io.IOException - in unknown circumstances
      BuildException - if ignoreNoncriticalErrors has not been set to true and a directory could not be created, for instance because it was already existing. Precisely, the codes 521, 550 and 553 will trigger a BuildException
    • execute

      public void execute() throws BuildException

      Overrides:
      execute in class Task
      Throws:
