[GRADLE-2310] Can't use System.console() when using the daemon Created: 16/May/12  Updated: 24/Jan/17  Resolved: 24/Jan/17

 Description   

In this environment, System.console() returns null.

Possible solutions:

1. Inject a console impl to be returned by System.console() that works with the daemon client (not sure if we can inject here)
2. Provide a "Gradle console" object that is daemon aware

I just ran into this as well, and landed here via http://forums.gradle.org/gradle/topics/standard_in_when_using_the_daemon.

It would be most convenient and natural to use System.console() as opposed to rolling one's own with System.in.

As the daemon is highly encouraged to be used, with lots of improvements coming thanks to 2.4 release, it would be great to use the console as well.

I'll put it on the list of contenders for 2.5.

The most expedient way of getting something done would be to contribute a fix. If this is something you're interested in, please mention so on the Gradle development list: https://groups.google.com/forum/#!forum/gradle-dev

I don't think this will be too hard to implement. The “hardest” part will be working out the public API for this, as we can't just use the JDK entry points as they are blocked off for extension.

+1 for fixing this, it would help my groovysh plugin as well. Maybe I can call System.console() to check whether the daemon is running at all?

Note that a simple swingbuilder can be used as a workaround, to query the user's input

I'm on Windows. I only get a console if I run Gradle in a Windows Prompt and the daemon is off. If I run it in Git Bash (which I'd prefer), the console is null.

Same problem here

This is still an issue.

Same issue here. I can't use System.in() while using gradle (in Java)
Any fixes?
