-------------------------------------------

Well, right now that's how the output processing works. Might can be tweaked though.

> Similar (if not completely same) with: [https://github.com/JetBrains/intellij-community/commit/707cf1427f66beb24faa5b8193217e52a8bb85d1] issue. In IntelliJ IDEA case, a fix has been published for version 2020.1. Can be used as reference.
> Basically, printf() and print() does not work until a newline, not even System.out.flush() will work. This only happens on Gradle projects, and when running through the IDE (does not happen to Maven/Ant). This does not happen to println() because it prints new line.
> Quite a breaking stuff, impossible to accept user input on the same line through the console.
> As an example to demonstrate the issue:
> {code:java}
> public static void main(String[] args) {
>         Scanner in = new Scanner(System.in);
>         
>         System.out.print("Please enter ABC: ");
>         in.next();
>         System.out.printf("DEF: ");
>         in.next();
>         System.out.println("GHI: ");
>         in.next();
>     }
> {code}
> Output:
> {code:java}
> JAVA_HOME="C:\Program Files\AdoptOpenJDK\jdk-14.0.1.7-hotspot"
> cd C:\repo\test-cli; ./gradlew --configure-on-demand -PrunClassName=Transaction.Transaction -x check runSingle
> Configuration on demand is an incubating feature.
> > Task :compileJava UP-TO-DATE
> > Task :processResources NO-SOURCE
> > Task :classes UP-TO-DATE> Task :runSingle
> ABC
> DEF
> Please enter ABC: DEF: GHI: 
> GHI
> BUILD SUCCESSFUL in 17s
> 2 actionable tasks: 1 executed, 1 up-to-date
> {code}
> A fix would be very appreciated, thank you.
