1. Add this as a dependency

• Maven

<dependencies>
    <dependency>
        <groupId>io.github.projectunified</groupId>
        <artifactId>mc-server-updater-lib</artifactId>
        <version>VERSION</version>
    </dependency>
</dependencies>

• Gradle

dependencies {
    compileOnly(group: 'io.github.projectunified', name: 'mc-server-updater-lib', version: 'VERSION')
}

2. Use the UpdateBuilder to create, execute the update process and get the result as UpdateStatus

import java.util.concurrent.CompletableFuture;

class Main {
  public static void main(String[] args) {
    UpdateBuilder builder = UpdateBuilder.updateProject("paper")
            .version("1.17.1")
            .outputFile("server.jar");

    // Execute the update process asynchronously
    CompletableFuture<UpdateStatus> future = builder.executeAsync();
    
    // Execute the update process synchronously
    UpdateStatus status = builder.execute();
  }
}

3. Do whatever you want with the UpdateStatus
