Documents4j 非法状态异常

Question

我正在尝试使用 documents4j (https://bintray.com/raphw/maven/documents4j) 以便使用以下代码将 docx 文件转换为 pdf：非常感谢你，我不知道如何让它工作

    package documents4j;


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 HelloPDF {
    public static void main(String[] args) {

        File wordFile = new File("c:/datos/Resultados.docx"), target = new File("c:/datos/Resultados.pdf");

        IConverter converter = LocalConverter.builder().baseFolder(new File("c:/datos/"))
                .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();

    }
}

但是我遇到了非法状态异常
