    • setRequiretools

      public void setRequiretools(boolean requireTools)

      Parameters:
      requireTools - the requireTools flag
    • setUsesystemin

      public void setUsesystemin(boolean useSystemIn)
      Set the useSystemIn flag. Setting this flag to false will cause this task to not read System.in. This will cause the child JVM to never receive any bytes when it reads System.in. Setting this flag to false is useful in some Unix environments where processes cannot be put in the background when they read System.in.
      Parameters:
      useSystemIn - the useSystemIn flag
    • setWaitforchild

      public void setWaitforchild(boolean waitForChild)
      Set the waitForChild flag. Setting this flag to true will cause this task to wait for the child JVM to finish executing before the task completes. Setting this flag to false will cause this task to complete immediately after it starts the execution of the child JVM. Setting it false emulates the "invalid input: '&'" background operator in most Unix shells and is most of set to false when launching server or GUI applications.
      Parameters:
      waitForChild - the waitForChild flag
    • setClassname

      public void setClassname(String mainClassName)
      Set the class name.
      Parameters:
      mainClassName - the class to execute main(String[])
    • setClasspath

      public void setClasspath(String classpath)
      Set the classpath.
      Parameters:
      classpath - the classpath
    • setDebug

      public void setDebug(boolean debug)
      Set the debug flag.
      Parameters:
      debug - the debug flag
    • setDisplayminimizedwindow

      public void setDisplayminimizedwindow(boolean displayMinimizedWindow)
      Set the displayMinimizedWindow flag. Note that this flag has no effect on non-Windows platforms. On Windows platform, setting this flag to true will cause a minimized window to be displayed in the Windows task bar while the child process is executing. This flag is usually set to true for server applications that also have their "waitForChild" attribute set to false via the setWaitforchild(boolean) method.
      Parameters:
      displayMinimizedWindow - true if a minimized window should be displayed in the Windows task bar while the child process is executing
    • setDisposeminimizedwindow

      public void setDisposeminimizedwindow(boolean disposeMinimizedWindow)
      Set the disposeMinimizedWindow flag. Note that this flag has no effect on non-Windows platforms. On Windows platform, setting this flag to true will cause any minimized window that is display by setting the "displayMinimizedWindow" attribute to true via the setDisplayminimizedwindow(boolean) to be automatically disposed of when the child JVM's main(String[]) returns. This flag is normally used for applications that don't explicitly call System.exit(int). If an application does not explicitly call System.exit(int), an minimized windows need to be disposed of for the child JVM to exit.
      Parameters:
      disposeMinimizedWindow - true if a minimized window in the Windows taskbar should be automatically disposed of after the child JVM's main(String[]) returns
    • setFailonerror

      public void setFailonerror(boolean failOnError)
      Set the failOnError flag.
      Parameters:
      failOnError - the failOnError flag
    • setMinimizedwindowtitle

      public void setMinimizedwindowtitle(String minimizedWindowTitle)
      Set the title for the minimized window that will be displayed in the Windows taskbar. Note that this property has no effect on non-Windows platforms.
      Parameters:
      minimizedWindowTitle - the title to set for any minimized window that is displayed in the Windows taskbar
    • setMinimizedwindowicon

      public void setMinimizedwindowicon(File minimizedWindowIcon)
      Set the icon file for the minimized window that will be displayed in the Windows taskbar. Note that this property has no effect on non-Windows platforms.
      Parameters:
      minimizedWindowIcon - the icon file to use for any minimized window that is displayed in the Windows taskbar
    • setOutput

      public void setOutput(File outputFile)
      Set the file that the child JVM's System.out and System.err will be redirected to. Output will only be redirected if the redirect flag is set to true via the setRedirectoutput(boolean) method.
      Parameters:
      outputFile - a File to redirect System.out and System.err to
    • setAppendoutput

      public void setAppendoutput(boolean appendOutput)
      Set the appendOutput flag. Setting this flag to true will cause the child JVM to append System.out and System.err to the file specified by the setOutput(File) method. Setting this flag to false will cause the child to overwrite the file.
      Parameters:
      appendOutput - true if output should be appended to the output file
    • setArgs

      public void setArgs(ArrayList args)
      Set the list of nested arg elements.
      Parameters:
      args - a list of String objects

      Parameters:
      sysProperties - a map of String objects
    • setRedirectoutput

      public void setRedirectoutput(boolean redirect)
      Set the redirect flag. Setting this flag to true will cause the child JVM's System.out and System.err to be redirected to file set using the setOutput(File) method. Setting this flag to false will cause no redirection.
      Parameters:
      redirect - true if System.out and System.err should be redirected
