When executing a simple programm that aims to write a string into an ods-File, i get an error in eclipse.
Here's the error:
java.lang.module.FindException: Unable to derive module descriptor for /home/benutzer/Documents/Java/Eclipse/FNetParser/src/jOpenDocument.jar Caused by: java.lang.module.InvalidModuleDescriptorException: JDOMAbout$Info.class found in top-level directory (unnamed package not allowed in module)
Now here's how I got there: I wrote a class that uses the jopendocument-1.5.rar library to write a string into a cell in an .ods-file. I downloaded the jar here: https://jopendocument.org/download.html (I downloaded version 1.5) and the code looks like this:
import java.io.File;
import java.io.IOException;
import org.jopendocument.dom.spreadsheet.Sheet;
import org.jopendocument.dom.spreadsheet.SpreadSheet;
public class SpreadSheetHandler {
public static void main() {
SpreadSheetHandler ssh = new SpreadSheetHandler();
ssh.writeStringToCell("L1", "Test");
}
public void writeStringToCell (String str_cell, String str_value) {
File odc_WpDaten = new File("/home/benutzer/Desktop/Aktien/20230103_Aktienliste.ods");
//odc_WpDaten.loadFrom("/home/benutzer/Desktop/Aktien/20230103_Aktienliste.ods");
Sheet sht_WpDaten;
try {
sht_WpDaten = SpreadSheet.createFromFile(odc_WpDaten).getSheet("Sheet1");
sht_WpDaten.getCellAt(str_cell).setValue("str_value");
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
All the programm is supposed to do is open an .ods file and write "Test" in cell L1. That's it.
I have added the jopendocument library to my project like other libraries before (Add library..., then add to build path...) I have also aligned to names of the jar file (renamed the .jar file "jopendocument.jar") and of the entry in the module-info.java file. I still get the error.
The content of module-info.java looks like this:
/**
*
*/
/**
* @author benutzer
*
*/
module FNetParser {
requires jOpenDocument;
}
It doesn't look like a coding problem to me. More like some issue with setting this ominous "module descriptor" in eclipse. Does anyone know where i can find the "module descriptor", that is mentioned in the error message?
I the module-info.java, "jopendocument" is underlined, when i hover over it, the tooltip reads: "Name of automatic module "jopendocument" is unstable. It is derived from the module's filename.
