Джена терпит неудачу, прося пропустить класс Xerces, в то время как Xerces 2 включен

Question

Я получаю ошибку

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/xerces/util/XMLChar
    at org.apache.jena.shared.impl.PrefixMappingImpl.checkLegal(PrefixMappingImpl.java:172)

при запуске простого примера Jena, но у меня есть эти две зависимости в моем Maven pom.xml файл:

<dependency>
    <groupId>org.apache.jena</groupId>
    <artifactId>apache-jena-libs</artifactId>
    <type>pom</type>
    <version>3.6.0</version>
</dependency>
<dependency>
    <groupId>xerces</groupId>
    <artifactId>xercesImpl</artifactId>
    <version>2.11.0</version>
</dependency>

Я проверил загружаемый архив Jena и его lib каталог содержит файл jar Xerces 2.11.0, поэтому версия верна.

Чего здесь не хватает?

Обновления:

AndyS указывает, что зависимость не нужна и что NoClassDefFoundError отличается от более распространенного ClassNotFoundException,

Ошибка происходит без зависимости. Что касается NoClassDefFoundError, не уверен, что может быть причиной этого. Мой код очень прост:

String filename = "test.jsonld";

Model model = ModelFactory.createDefaultModel() ;
model.read(filename) ;

с test.jsonld являющийся

{
    "@id": "http://store.example.com/",
    "@type": "Store",
    "name": "Links Bike Shop",
    "description": "The most \"linked\" bike store on earth!"
}

Полный вывод, включая исключения, приведен ниже. Я не уверен, как начать устранение неполадок, какие-либо предложения?

Maven зависимости для проекта, который зависит исключительно от org.apache.jena:apache-jena-libs:pom:3.6.0 должен выглядеть так:

[INFO] org.apache.jena:jena-reports-version:jar:0.0.0-SNAPSHOT [INFO] \- org.apache.jena:apache-jena-libs:pom:3.6.0:compile [INFO] +- org.apache.jena:jena-tdb:jar:3.6.0:compile [INFO] | \- org.apache.jena:jena-arq:jar:3.6.0:compile [INFO] | +- org.apache.jena:jena-core:jar:3.6.0:compile [INFO] | | +- org.apache.jena:jena-iri:jar:3.6.0:compile [INFO] | | +- xerces:xercesImpl:jar:2.11.0:compile [INFO] | | | \- xml-apis:xml-apis:jar:1.4.01:compile ...

Если он не находит xerces, то может быть что-то локальное, мешающее.
