java.lang.IllegalAccessError: class lombok.javac.apt.LombokProcessor cannot access class com.sun.tools.javac.processing.JavacProcessingEnvironment

I am somewhat new to coding and am trying to use the Lombok plugin to automatically create Getters/Setters e.t.c. for my fields of a specific class. In doing so I get greeted with the following error:

The error:

java: java.lang.IllegalAccessError: class lombok.javac.apt.LombokProcessor (in unnamed module @0x3b67ef9b) cannot access class com.sun.tools.javac.processing.JavacProcessingEnvironment (in module jdk.compiler) because module jdk.compiler does not export com.sun.tools.javac.processing to unnamed module @0x3b67ef9b

After doing some searching online, I found out that this error is related to an issue in OpenJDK 15 but I am currently using OpenJDK 16, hence why I am confused that I am still getting this error.

This thread claims to have a solution: https://github.com/rzwitserloot/lombok/issues/2681#issuecomment-748616687 but after implementing the plugin, it does not seem to make any difference and I still receive the error.

I have most likely made a trivial mistake since I am a beginner but if someone knows what I am missing please let me know.

Class Using @Data (Lombok):

import lombok.Data;

@Data
public class Ingredient {

    private final String id;
    private final String name;
    private final Type type;

    public enum Type {
        WRAP, PROTEIN, VEGGIES, CHEESE, SAUCE
    }

}

Solution

Switch to at least the 1.18.22 version of Lombok that contains the fix

<dependency>
  <groupId>org.projectlombok</groupId>
  <artifactId>lombok</artifactId>
  <version>1.18.22</version>
</dependency>
