What happened to: org.apache.ws.commons.schema.XmlSchemaCollection.read(InputSource)?

The correct dependency is

<dependency>
    <groupId>org.apache.ws.xmlschema</groupId>
    <artifactId>xmlschema-core</artifactId>
    <version>2.0.1</version>
</dependency>

Please change your dependency to 2.0.1 or 2.0.2

legacy 1.4.7 don't have the method defined

public XmlSchema read(Source source) {
    if (source instanceof SAXSource) {
        return read(((SAXSource)source).getInputSource());
    }

check the 1.4.x javadoc and 2.x javadoc
