Jar выдает ошибки из Java-проекта, который работает нормально ⇐ JAVA

[Anonymous]

I have made a little project, which I try to convert into exe file now. And to do so I need to make a jar file first, where the problems arise:

Here is what jar program throws.

C:> C:\[path]\IdeaProjects\Erpegkraj\out\artifacts\Erpegkraj_jar\Erpegkraj.jar ERROR StatusLogger Log4j2 could not find a logging implementation. Please add log4j-core to the classpath. Using SimpleLogger to log to the console...

This is a part of code I think it has problems with:

public static String readSheetsLine(File sheetsPath, String sheetsName, String name) throws IOException { String text = ""; OPCPackage package; Workbook wb; try { package = OPCPackage.open(sheetsPath); wb = new XSSFWorkbook(package); } catch (InvalidFormatException e) { throw new RuntimeException(e); } Sheet sheet = notatnik.getSheet(sheetsName); for(Row r: sheet){ String value = r.getCell(0).getStringCellValue(); if(Objects.equals(value, nazwa)){ for (Cell c : r){ c.setCellType(CellType.STRING); String typ = sheet.getRow(0).getCell(c.getColumnIndex()).getStringCellValue(); if (!Objects.equals(typ, "")){ tekst += typ + "#"+ c.getStringCellValue()+"~"; }else break; } break; } if (Objects.equals(value, "")) break; } wb.close(); package.close(); return text; } I have tried everything I could find on the Internet about "InvalidOperationException", but nothing prevailed.

I would be thankful for any kind of help.
