Constructor Detail

ExtSSHExec

public ExtSSHExec()

Constructor for SSHExecTask.

Method Detail

setCommand

public void setCommand(java.lang.String command)

Sets the command to execute on the remote host.

Parameters:

command - The new command value

setCommandResource

public void setCommandResource(java.lang.String f)

Sets a commandResource from a file

Parameters:

f - the value to use.

Since:

Ant 1.7.1

setTimeout

public void setTimeout(long timeout)

The connection can be dropped after a specified number of milliseconds. This is sometimes useful when a connection may be flaky. Default is 0, which means "wait forever".

Parameters:

timeout - The new timeout value in seconds

setOutput

public void setOutput(java.io.File output)

If used, stores the output of the command to the given file.

Parameters:

output - The file to write to.

setInput

public void setInput(java.io.File input)

If used, the content of the file is piped to the remote command

Parameters:

input - The file which provides the input data for the remote command

setInputProperty

public void setInputProperty(java.lang.String inputProperty)

If used, the content of the property is piped to the remote command

Parameters:

inputProperty - The property which contains the input data for the remote command.

setAppend

public void setAppend(boolean append)

Determines if the output is appended to the file given in setOutput. Default is false, that is, overwrite the file.

Parameters:

append - True to append to an existing file, false to overwrite.

setOutputproperty

public void setOutputproperty(java.lang.String property)

If set, the output of the command will be stored in the given property.

Parameters:

property - The name of the property in which the command output will be stored.

setAllocatePty

public void setAllocatePty(boolean b)

Allocate a Pseudo-Terminal. If set true, the SSH connection will be setup to run over an allocated pty.

Parameters:

b - if true, allocate the pty. (default false

getExitStatus

public int getExitStatus()

Return exitStatus of the remote execution, after it has finished or failed. The return value prior to retrieving the result will be -1. If that value is returned after the task has executed, it indicates that an exception was thrown prior to retrieval of the value.

addEnv

public void addEnv(org.apache.tools.ant.types.Environment.Variable env)

Add an Env element

Parameters:

env - element

getDisconnectHolder
