Close the streams belonging to the given Process.

  Close the streams belonging to the given Process.
Parameters:
- process - the Process.

  Runs a process defined by the command line and returns its exit status.

  Runs a process defined by the command line and returns its exit status.
Returns: the exit status of the subprocess or INVALID.
Throws:
- java.io.IOException - The exception is thrown, if launching of the subprocess failed.

  Returns the commandline used to create a subprocess.

  Returns the commandline used to create a subprocess.
Returns: the commandline used to create a subprocess.

  Returns the environment used to create a subprocess.

  Returns the environment used to create a subprocess.
Returns: the environment used to create a subprocess.

  Query the exit value of the process.

  Query the exit value of the process.
Returns: the exit value or Execute.INVALID if no exit value has been received.

  Find the list of environment variables for this process.

  Find the list of environment variables for this process.
Returns: a vector containing the environment variables. The vector elements are strings formatted like variable = value.

  Return the working directory.

  Return the working directory.
Returns: the directory as a File.
Since: Ant 1.7

  Did this execute return in a failure.

  Did this execute return in a failure.
Returns: true if and only if the exit code is interpreted as a failure
Since: Ant1.7
See Also: Execute.isFailure(int),

  Checks whether exitValue signals a failure on the current system (OS specific).

  Checks whether exitValue signals a failure on the current system (OS specific).

Note that this method relies on the conventions of the OS, it will return false results if the application you are running doesn't follow these conventions. One notable exception is the Java VM provided by HP for OpenVMS - it will return 0 if successful (like on any other platform), but this signals a failure on OpenVMS. So if you execute a new Java VM on OpenVMS, you cannot trust this method.

Returns: true if exitValue signals a failure.
Parameters:
- exitValue - the exit value (return code) to be checked.

  Test for an untimely death of the process.

  Test for an untimely death of the process.
Returns: true if a watchdog had to kill the process.
Since: Ant 1.5

  Creates a process that runs a command.

  Creates a process that runs a command.
Returns: the process started.
Parameters:
- project - the Project, only used for logging purposes, may be null.
- command - the command to run.
- env - the environment for the command.
- dir - the working directory for the command.
- useVM - use the built-in exec command for JDK 1.3 if available.
Throws:
- java.io.IOException - forwarded from the particular launcher used.
Since: Ant 1.5

  A utility method that runs an external command. Writes the output and
error streams of the command to the project log.
Parameters:
- task - The task that the command is part of. Used for logging
- cmdline - The command to execute.
Throws:
- BuildException - if the command does not exit successfully.

  Set the name of the antRun script using the project's value.

  Set the name of the antRun script using the project's value.
Parameters:
- project - the current project.
Throws:
- BuildException - not clear when it is going to throw an exception, but it is the method's signature.

  Sets the commandline of the subprocess to launch.

  Sets the commandline of the subprocess to launch.
Parameters:
- commandline - the commandline of the subprocess to launch.

  Sets the environment variables for the subprocess to launch.

  Sets the environment variables for the subprocess to launch.
Parameters:
- env - array of Strings, each element of which has an environment variable settings in format key=value.

  Set the exit value.

  Set the exit value.
Parameters:
- value - exit value of the process.

  Set whether to propagate the default environment or not.

  Set whether to propagate the default environment or not.
Parameters:
- newenv - whether to propagate the process environment.

  Set whether or not you want the process to be spawned.

  Set whether or not you want the process to be spawned.
Default is not spawned.
Parameters:
- spawn - if true you do not want Ant to wait for the end of the process.

  Set the stream handler to use.

  Set the stream handler to use.
Parameters:
- streamHandler - ExecuteStreamHandler.
Since: Ant 1.6

  Launch this execution through the VM, where possible, rather than through the OS's shell.

  Launch this execution through the VM, where possible, rather than through
the OS's shell. In some cases and operating systems using the shell will
allow the shell to perform additional processing such as associating an
executable with a script, etc.
Parameters:
- useVMLauncher - true if exec should launch through the VM, false if the shell should be used to launch the command.

  Sets the working directory of the process to execute.

  Sets the working directory of the process to execute.

This is emulated using the antRun scripts unless the OS is Windows NT in which case a cmd.exe is spawned, or MRJ and setting user.dir works, or JDK 1.3 and there is official support in java.lang.Runtime.
Parameters:
- wd - the working directory of the process.

  Starts a process defined by the command line.

  Starts a process defined by the command line.
Ant will not wait for this process, nor log its output.
Throws:
- java.io.IOException - The exception is thrown, if launching of the subprocess failed.
Since: Ant 1.6

  ByteArrayOutputStream#toString doesn't seem to work reliably on OS/390, at least not the way we use it in the execution context.

  ByteArrayOutputStream#toString doesn't seem to work reliably on
OS/390, at least not the way we use it in the execution
context.
Returns: the output stream as a string, read with special encodings in the case of z/os and os/400.
Parameters:
- bos - the output stream that one wants to read.
