Where the first error type is for the fields in this class:
package com.mangusbrother.akka.calculator.lib.operation.multiply;
import com.mangusbrother.akka.calculator.lib.operation.MathematicalResult;
import lombok.Data;
/**
* Created by Mangusbrother on 14/02/2016.
*/
@Data
public class MultiplyResult implements MathematicalResult {
private static final long serialVersionUID = 738641818941986L;
private final int firstNumber;
private final int secondNumber;
private final int result;
}
and the second error is when a class tries to access getters from lombok classes
My maven pom.xml has the following in it:
<properties>
<lombok.version>1.16.6</lombok.version>
</properties>
<dependencies>
<dependency>

Answer
I don’t know why but you got compiler error because of maven-compiler-plugin. If you can please change plugin version to 3.5 and check if it will work.
