That is because commons-codec dependency is set as optional. You need to change your pom.xml to this: <div><div>        &lt;dependency&gt;</div><div>            &lt;groupId&gt;commons-codec&lt;/groupId&gt;</div><div>            &lt;artifactId&gt;commons-codec&lt;/artifactId&gt;</div>

<div>            &lt;version&gt;1.4&lt;/version&gt;</div><div>            &lt;!--scope&gt;optional&lt;/scope--&gt;</div><div>        &lt;/dependency&gt;    </div><div><br></div><div>I had the same issue in core, and I solved it this way.</div>
