eXo Platform provides the jQuery library 3.2.1 as a jquery module, the configuration of this module can be found in the eXoResources.war file. To reuse this jQuery version, just declare a dependency over it:

<portlet>

  <name>RequireJSPortlet</name>

  <module>

    <depends>

      <module>jquery</module>

    </depends>

</portlet>

The default jquery module alias is $, so if you are using it, it should be named $ in the self-executing function:

If your library uses a different name, such as jQuery, the XML as tag should be used:

<portlet>

  <name>RequireJSPortlet</name>

  <module>

    <depends>

      <module>jquery</module>

      <as>jQuery</as>

    </depends>

</portlet>

With the following self-executing function:

(function($) {
    ...
}(jQuery)
