Adding xercesImpl dependency then got error: the package javax.xml is accessible from more than one module: <unnamed>, java.xmlJava(8390063)

the goal is to validate generated XML with XSD 1.1. Implemented code to validate:

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;
    }
}

After implement the code, got Error: Element 'assert' Is Invalid, Misplaced, Or Occurs Too Often, because the XSD to validate is 1.1 version, not 1.0. Then, found the open source dependency that supports XSD 1.1, Xerces. The dependency that implemented is:

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

But, got error on imported Class from the code above, sequentially:

- The package javax.xml is accessible from more than one module: <unnamed>, java.xmlJava(8390063)
- The package javax.xml.transform.stream is accessible from more than one module: <unnamed>, java.xmlJava(8390063)
- The package javax.xml.validation is accessible from more than one module: <unnamed>, java.xmlJava(8390063)

I'm so stuck and frustrated, because the validation using XSD 1.1 is a mandatory. Please help. Terima kasih.
