Unable to add a module to wildfly 9, module not found exception when loading war that refers to it

in my WEB-INF directory jboss-deployment-structure.xml

<jboss-deployment-structure>
    <deployment>
        <dependencies>
            <module name="com.ticomgeo.crowbar" />
        </dependencies>

</jboss-deployment-structure>

in $JBOSS_HOME/modules/com/ticomgeo/crowbar/main modules.xml

<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.1" name="com.ticomgeo.crowbar">
