Maven project does not recognize some artifacts

Question

I'm new to Maven, this might be a dumb question. My problem is that I created a dynamic web project in the Eclipse Luna version. I added some artifacts to the room. JAXRS and DOM4J. He loaded all the cans.

I can import the JAXRS class into my code without adding jaxrs in the lib file. but I cannot access the DOM4J class. I use the web scope as my server.

Please help me fix the dom4j problem. Thanks in advance.

POM file. I deleted some entries from this post.

My way to class

<?xml version="1.0" encoding="UTF-8"?>
<classpath>
    <classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/WebSphere Application Server v8.0 JRE">

            <attribute name="owner.project.facets" value="java"/>
        </attributes>
    </classpathentry>
    <classpathentry kind="src" path=".apt_generated">
        <attributes>
            <attribute name="optional" value="true"/>
        </attributes>
    </classpathentry>
    <classpathentry kind="src" path="src/main/java"/>
    <classpathentry kind="src" path="src/main/resources"/>
    <classpathentry kind="con" path="org.eclipse.jst.server.core.container/com.ibm.ws.ast.st.runtime.runtimeTarget.v80/WebSphere Application Server v8.0">

    <classpathentry kind="con" path="org.eclipse.jst.j2ee.internal.module.container"/>
    <classpathentry kind="output" path="WebContent/WEB-INF/classes"/>
</classpath>

I use Websphere 8 as my server.
