      Sets the remote working directory
    • setNewer

      public void setNewer(boolean newer)
      A synonym for depends. Set to true to transmit only new or changed files.
    • setDepends

      public void setDepends(boolean depends)

      public void setChmod(String theMode)
      Sets the file permission mode (Unix only) for files sent to the server.
    • addFileset

      public void addFileset(org.apache.tools.ant.types.FileSet set)
      A set of files to upload or download
    • setAction

      public void setAction(Sftp.Action action) throws org.apache.tools.ant.BuildException
      Deprecated.
      Sets the FTP action to be taken. Currently accepts "put", "get", "del", "mkdir", "chmod" and "list".
      Throws:
      org.apache.tools.ant.BuildException
    • setSkipFailedTransfers

      public void setSkipFailedTransfers(boolean skipFailedTransfers)
      If true, enables unsuccessful file put, delete and get operations to be skipped with a warning and the remainder of the files still transferred.
    • setIgnoreNoncriticalErrors

      public void setIgnoreNoncriticalErrors(boolean ignoreNoncriticalErrors)
      set the flag to skip errors on directory creation. (and maybe later other server specific errors)
    • checkConfiguration

      protected void checkConfiguration() throws org.apache.tools.ant.BuildException
      Checks to see that all required parameters are set.
      Throws:
      org.apache.tools.ant.BuildException
    • transferFiles

      protected int transferFiles(SftpClient sftp, org.apache.tools.ant.types.FileSet fs) throws IOException, org.apache.tools.ant.BuildException
      For each file in the fileset, do the appropriate action: send, get, delete, or list.
      Throws:
      IOException
      org.apache.tools.ant.BuildException
    • transferFiles

      protected void transferFiles(SftpClient sftp) throws IOException, org.apache.tools.ant.BuildException
      Sends all files specified by the configured filesets to the remote server.
      Throws:
      IOException
      org.apache.tools.ant.BuildException
    • resolveFile

      protected String resolveFile(String file)
      Correct a file path to correspond to the remote host requirements. This implementation currently assumes that the remote end can handle Unix-style paths with forward-slash separators. This can be overridden with the separator task parameter. No attempt is made to determine what syntax is appropriate for the remote host.
    • createParents

      protected void createParents(SftpClient sftp, String filename) throws IOException, org.apache.tools.ant.BuildException
      Creates all parent directories specified in a complete relative pathname. Attempts to create existing directories will not cause errors.
      Throws:
      IOException
      org.apache.tools.ant.BuildException
    • isUpToDate

      protected boolean isUpToDate(SftpClient sftp, File localFile, String remoteFile) throws IOException, org.apache.tools.ant.BuildException
      Checks to see if the remote file is current as compared with the local file. Returns true if the remote file is up to date.
      Throws:
      IOException
      org.apache.tools.ant.BuildException
    • sendFile

      protected void sendFile(SftpClient sftp, String dir, String filename) throws IOException, org.apache.tools.ant.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.
      Throws:
      IOException
      org.apache.tools.ant.BuildException
    • delFile

      protected void delFile(SftpClient sftp, String filename) throws IOException, org.apache.tools.ant.BuildException
      Delete a file from the remote host.
      Throws:
      IOException
      org.apache.tools.ant.BuildException
    • chmod

      protected void chmod(SftpClient sftp, String filename) throws IOException, org.apache.tools.ant.BuildException
      Throws:
      IOException
      org.apache.tools.ant.BuildException
    • getFile

      protected void getFile(SftpClient sftp, String dir, String filename) throws IOException, org.apache.tools.ant.BuildException
      Retrieve a single file to the remote host. filename may contain a relative path specification.

      The file will then be retreived 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.

      Throws:
      IOException
      org.apache.tools.ant.BuildException
    • makeRemoteDir

      protected void makeRemoteDir(SftpClient sftp, String dir) throws org.apache.tools.ant.BuildException
      Create the specified directory on the remote host.
      Parameters:
      sftp - The SFTP client connection
      dir - The directory to create
      Throws:
      org.apache.tools.ant.BuildException
    • execute

      public void execute(SshClient ssh) throws org.apache.tools.ant.BuildException
      Runs the task.
      Overrides:
      execute in class SshSubTask
      Throws:
      org.apache.tools.ant.BuildException
    • executeSFTPTask

      protected void executeSFTPTask(SshClient ssh) throws org.apache.tools.ant.BuildException
      Throws:
