Of course, sorry.
But I think it’s because we are in 10.4 and I just see in the issue tracker that this problem was fixed in 10.5
Sample source file:
package com.my.package;
import lombok.*;
import java.util.Map;
@Getter
@Setter
@NoArgsConstructor
@Data
@EqualsAndHashCode(callSuper = true)
public class MyDTO {
private Map<String, Object> someData;
}
