Does it cause any problems if I have @Builder annotation in my object model?

[hyunjoolee]

I am using poiji like below. Could you please answer my question.

@Getter
@excelsheet("Model")
public class model {

@ExcelRow
private int rowIndex;

@ExcelCell(1)
private String name;

@ExcelCell(2)
private String address;

@ExcelCell(3)
private String number;

}

@builder
@Getter
@excelsheet("model2")
public class model2 {

@ExcelRow
private int rowIndex;

@ExcelCell(1)
private String name2;

@ExcelCell(2)
private String address2;

@ExcelCell(3)
private String number2;

}

Below are sample code to use Poiji.

---

PoijiOptions.PoijiOptionsBuilder optionsBuilder = PoijiOptions.PoijiOptionsBuilder.settings();
for(int sheetIndex = 0; sheetIndex < TOTAL_SHEET_COUNT; sheetIndex++) {
optionsBuilder.sheetIndex(sheetIndex).skip(1);
if(sheetIndex == 1)
List < model > model_list = Poiji.fromExcel(file, model.class, optionsBuilder.build());
esle if(sheetIndex == 2)
List < model2 > model2_list = Poiji.fromExcel(file, model2.class, optionsBuilder.build());
}

---

When I run the above code, I get the error message below: Only Model2 has an error. I think the only difference between Model and Model2 is the @builder annotation.
Should I avoid using the @builder annotation on object model when using the Poiji library?

My development environment is based on windows 10, springboot 3.1.2, jdk17, poiji 4.1.2.
