添加 xercesImpl 依赖项然后得到错误：包 javax.xml 可以从多个模块访问：<unnamed>, java.xmlJava(8390063)

问题描述

目标是使用 XSD 1.1 验证生成的 XML。用于验证的实现代码：

num_nodes

执行代码后，得到错误：元素 'assert' 无效、错位或经常发生，因为要验证的 XSD 是 1.1 版本，而不是 1.0。然后，找到了支持XSD 1.1的开源依赖，Xerces。实现的依赖是：

import javax.xml.XMLConstants;
import javax.xml.transform.stream.StreamSource;
import javax.xml.validation.Schema;
import javax.xml.validation.SchemaFactory;
import javax.xml.validation.Validator;

private boolean validateAgainstXSD(InputStream xml,InputStream xsd) {
    try {
        SchemaFactory factory = 
            SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
        Schema schema = factory.newSchema(new StreamSource(xsd));
        Validator validator = schema.newValidator();
        validator.validate(new StreamSource(xml));
        return true;
    } catch(Exception ex){
        ex.printstacktrace();
        return false;
    }
}

然后，pom.xml：

<dependency>
        <groupId>xerces</groupId>
        <artifactId>xercesImpl</artifactId>
        <version>2.12.1</version>
</dependency>

但是，从上面的代码中导入的类出现错误，顺序如下：

我很困惑和沮丧，因为使用 XSD 1.1 的验证是强制性的。请帮忙。 Terima kasih。
