Errors occurred during the build in Eclipse

Question

I am new to Eclipse. I am facing one error whenever I am creating any project or package.

Errors occurred during the build.
Errors running builder 'Java Builder' on project 'Hello'.
java.lang.NullPointerException

Also on running a small "Hello world program " in java Here is my program:

public class MyHello {
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        System.out.print("Hello World");
    }

}

I am getting this error:

Picked up _JAVA_OPTIONS: -Djava.net.preferIPv4Stack=true
Error occurred during initialization of boot layer
java.lang.module.FindException: Module Hello not found

Here is my java version:

Picked up _JAVA_OPTIONS: -Djava.net.preferIPv4Stack=true
java version "12" 2019-03-19
Java(TM) SE Runtime Environment (build 12+33)
