Compiling Java code for lower JRE version [duplicate]

Question

I have a Java 10+ based source code which I want to compile for a lower version of Java (e.g. Java 8) without modifications of the source itself. I want users with Java 8 installed to be able to run the executable JAR file.

Is this possible and if yes, how can this be done using maven? I didn't find any reasonable guides on this. Lowering the source and target compiler options does not work: I still get the version mismatch error.

LauncherClient.java:

import lombok.Getter;
import lombok.val;

public class LauncherClient
{
    @Getter
    private String lombok = "Lombok";

    public static void main(String[] arguments)
    {
        val launcherClient = new LauncherClient();
        var message = "Hello world, ";
        System.out.println(message + launcherClient.getLombok());
    }
}

When running the executable JAR via the command line using Java 8:

java -jar Java11Test-1.0-SNAPSHOT.jar
Error: A JNI error has occurred, please check your installation and try again
Exception in thread "main" java.lang.UnsupportedClassVersionError: LauncherClient has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0

Running it using Java 11 works fine:

"C:\Program Files\Java\jdk-11.0.1\bin\java.exe" -jar Java11Test-1.0-SNAPSHOT.jar
Hello world, Lombok
