I need to programmatically run a batch file from my Eclise plug-in. The
batch file starts a command line tool. When it is running I need to input
a command and get the output - again programmatically.
What's a good way to do this in Eclipse?
I tried to use Java's:
Runtime.getRuntime().exec(...);
but nothing seems to work, no console appears.
I also tried to create my own concole with:
MessageConsole console = new MessageConsole("My Console", null);
ConsolePlugin.getDefault().getConsoleManager().addConsoles(n ew
IConsole[]{console});
MessageConsoleStream stream = console.newMessageStream();
stream.println("Hello, world!");
But it seems this is just a text concole that will not help me run the
batch file.
The last thing I tried is to run my batch file as an External Tool. This
works OK with:
IOConsoleOutputStream stream = ((IOConsole) consoles[0]).newOutputStream();
stream.write("Hello, world!");
But the text is not treated as a command as if the user typed it (green
color).
Any way to get this to work?

Have you tried to start the batch file with cmd.exe?
Process p = Runtime.getRuntime().exec(new String[]{"cmd.exe", "/c", "test.bat"},
null, null);
You might have a look at Apache Ant's Execute class to get an idea of working
with input and output streams on a Process.

Thanks this seems to work, but printing to the console when the tool is
running doesn't. Here's what I have:
Runtime r = Runtime.getRuntime();
Process p = r.exec(new String[] {"cmd.exe", "/c", "start", "cli.bat"},
null, new File("C:\\Dir1\\Dir2"));
PrintWriter writer = new PrintWriter(p.getOutputStream());
writer.println("help");
writer.close();
Actually I think that using the External Tools console would be better.
But I have the same problem with writing to it when the tool is running.
