Error when converting office files to pdf with documents4J: Class path contains multiple SLF4J bindings

I am trying to use documents4J to convert the office files and images to PDF, but am getting "Class path contains multiple SLF4J bindings".

Here is my current code:

package documentsForJ;
import java.io.File;
import java.util.concurrent.Future;
import java.util.concurrent.TimeUnit;
import com.documents4j.api.DocumentType;
import com.documents4j.api.IConverter;
import com.documents4j.job.LocalConverter;

public class App {
    public static void main(String[] args) {

        File wordFile = new File("test.doc"), target = new File("test.pdf");

        IConverter converter = LocalConverter.builder().baseFolder(new File("G:\\documentsForJ\\target"))
                .workerPool(20, 25, 2, TimeUnit.SECONDS)
                .processTimeout(5, TimeUnit.SECONDS).build();

        Future<Boolean> conversion = converter.convert(wordFile).as(DocumentType.DOCX).to(target).as(DocumentType.PDF)
                // .prioritizeWith(1000) // optional
                .schedule();

    }
}

I have bind on the following Jars:

When I run the Application, I get the following Error:

The generated VBS C:\temp\excel_start1565707660.vbs gives the following error:enter image description here

And that is the code of the generated vbs:

  On Error Resume Next

    ' Signal that the conversion was successful.

    WScript.Quit -4

  End If

End Function

' Execute the script.
Call ConvertFile( arguments.Unnamed.Item(0), arguments.Unnamed.Item(1), CInt(arguments.Unnamed.Item(2)) )

Why is this error happening, and how can the problem be fixed?

This problem is most likely resolved in the newly released documents4j version 1.0.3 which adds proper escaping to the conversion script arguments. Previously, no arguments were escaped what can cause confusion when VBScript processes the script arguments as observed by you.
