Spring-Drools Integration: Referenced file (kie-spring.xsd) contains errors

Question

I'm trying to use drools with Spring. Spring version 4.01 Drools/Kie version 6.0.1

My kie-context.xml has the following error (in Eclipse):

Referenced file contains errors (http://drools.org/schema/kie-spring.xsd). For more information, right click on the message in the Problems View and select "Show Details..."

kie-context.xml: (imported in applicationContext.xml)

    <?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:kie="http://drools.org/schema/kie-spring"

    <kie:kmodule id="ng-rule-server">

            <kie:ksession name="ksession1" type="stateless" />
        </kie:kbase>
    </kie:kmodule>

    <bean id="kiePostProcessor" class="org.kie.spring.KModuleBeanFactoryPostProcessor" />
</beans>

Relevant pom.xml:

<drools.version>6.0.1.Final</drools.version>

Can anybody see what's wrong with my set up?

The right location can also be referred to by using the classpath : URL handler

xmlns:kie="http://drools.org/schema/kie-spring" xsi:schemaLocation="http://drools.org/schema/kie-spring classpath:org/kie/spring/kie-spring-6.0.0.xsd"
