Step 1. Add the JitPack repository to your build file

Add it in your root settings.gradle at the end of repositories:

	dependencyResolutionManagement {
		repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
		repositories {
			mavenCentral()
			maven { url 'https://jitpack.io' }
		}
	}

Add it in your settings.gradle.kts at the end of repositories:

	dependencyResolutionManagement {
		repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
		repositories {
			mavenCentral()
			maven { url = uri("https://jitpack.io") }
		}
	}

Add to pom.xml

	<repositories>
		<repository>
		    <id>jitpack.io</id>
		    <url>https://jitpack.io</url>
		</repository>
	</repositories>

Add it in your build.sbt at the end of resolvers:

 
    resolvers += "jitpack" at "https://jitpack.io"

Add it in your project.clj at the end of repositories:

 
    :repositories [["jitpack" "https://jitpack.io"]]

Step 2. Add the dependency

	dependencies {
		implementation 'com.github.jline:jline3:jline-3.28.0'
	}

	dependencies {
		implementation("com.github.jline:jline3:jline-3.28.0")
	}

	<dependency>
	    <groupId>com.github.jline</groupId>
	    <artifactId>jline3</artifactId>
	    <version>jline-3.28.0</version>
	</dependency>


                            
    libraryDependencies += "com.github.jline" % "jline3" % "jline-3.28.0"


                            
    :dependencies [[com.github.jline/jline3 "jline-3.28.0"]]

Quick Start

Here's a simple example to get you started:

import org.jline.reader.*;
import org.jline.reader.impl.*;
import org.jline.terminal.*;
import org.jline.terminal.impl.*;

public class HelloJLine {
    public static void main(String[] args) {
        try {
            // Create a terminal
            Terminal terminal = TerminalBuilder.builder()
                    .system(true)
                    .build();

            // Create line reader
            LineReader reader = LineReaderBuilder.builder()
                    .terminal(terminal)
                    .build();

            // Prompt and read input
            String line = reader.readLine("JLine > ");

            // Print the result
            System.out.println("You entered: " + line);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
