Import java libraries in local instance of compiler explorer

[anoojg]

Hi.
I am trying to run a local instance of compiler explorer with java compiler. I am facing issues while importing libraries.

java version: openjdk version "11.0.16" 2022-07-19
javac version: javac 11.0.16

Is there a specific way to install and import libraries?
Any help would be appreciated.

Complete Error:
Program returned: 1
Program stderr

Error: A JNI error has occurred, please check your installation and try again

Have you done any modification to the java properties files in /etc/config/ inside the Compiler Explorer repo?

Can you also send the code as plaintext instead of a screenshot?

Thanks for replying @matsjla

I have not modified java properties file.

Code used:

import java.util.Scanner;

class main {
  public static void main_(String[] args) {

    // creates an object of Scanner
    Scanner input = new Scanner(System.in); 

    System.out.print("Enter your name: ");

    // takes input from the keyboard
    String name = input.nextLine();

    // prints the name
    System.out.println("My name is " + name);

    // closes the scanner
    input.close();
  }
}

It seems that Java 11 gives this error if you don't capitalize your Main class

In newer versions you get a more usable error

@partouf I have upgraded to java18, it is working now.

Thank you for your support.
