Provide a pseudoterminal for the running/debugging console

The current default when running or debugging Java programs is to launch it in the integrated terminal, using a generated command that usually gets quite verbose. By setting java.debug.settings.console to internalConsole, users can get more clean output of their program, but the problem is that VS Code doesn't support user input from the debug console.

Therefore, it would be nice if the extension provided the option to launch a pseudoterminal for the program when running or debugging, which only shows the output of the program, and accepts user input. I think this is a much better user experience for most people, since the output of the program is what's important, not the full command used to launch it. Of course, that information may still be useful to some, and for debugging purposes, which is why I think the pseudoterminal should be just another option in java.debug.settings.console. Perhaps the pseudoterminal could be the default option, like in the Eclipse IDE:

I believe implementing this should be possible using the Pseudoterminal interface by passing ExtensionTerminalOptions to vscode.window.createTerminal. Then it should just be a matter of launching the java program in the background, and redirecting it's stdin/stdout to the pseudoterminal. I would have a go at implementing it myself if I had time, but unfortunately I'm quite busy with other projects right now. If anyone has time to work on this, it would be a really nice feature to have - I've heard multiple people who want a less verbose console but who also need support for stdin.

Come to think of it, you may also be able to use createTerminal with TerminalOptions instead, but without experimenting I can't quite tell whether or not it will be able to achieve the same result as a pseudoterminal. The advantage would be that it's a little easier to implement. I'm thinking it might be possible to use the JRE path for shellPath, put the JVM and program arguments in shellArgs, and then use cwd instead of generating a cd command.

Current Result

"java.debug.settings.console": "integratedTerminal"

"java.debug.settings.console": "internalConsole"

Expected Result

"java.debug.settings.console": "pseudoTerminal"

Beginne damit, die Verarbeitung von java.debug.settings.console und den Startpfad der Ausführungs-/Debugging-Konsole zu lokalisieren. Lies die in diesem Issue referenzierten VS Code-APIs Pseudoterminal, ExtensionTerminalOptions und TerminalOptions. Als abgeschlossen gilt die Arbeit, wenn eine Option pseudoTerminal das Java-Programm mit sauberer Ausgabe startet und sowohl beim Ausführen als auch beim Debuggen stdin akzeptiert.
