我试图使用documents4j将Office文件和图像转换为PDF，但得到"* 类路径包含多个SLF4J绑定 *"。
下面是我目前的代码：

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();

    }
}

我已绑定以下广口瓶：

• 文档4j-api-1.0.2.jar文档4j-client-1.0.2.jar
• documents4j-client-standalone-1.0.2-shaded.jar
• documents4j-local-1.0.2.jar

• 文档4j-转换器-1.0.2.jar文档4j-实用程序-全部-1.0.2.jar

当我运行应用程序时，我得到以下错误：

为什么会发生此错误？如何修复此问题？
