Adding a version number to a CSS file

Looking for a solution to automate updating references to CSS files in JSF, possibly through tools like Ant. Does anyone have recommendations on common practices or existing automated tools for this task?

I aim to simplify the deployment process by ensuring that any changes made to CSS files are automatically downloaded by clients without requiring them to clear their cache. Appreciate any assistance or advice!

If you want to take advantage of JSF's built-in resource library versioning feature, the first step is to create a resource library in your webapp's /resources folder if you haven't already done so. Once that's set up, you can add a version subfolder using the pattern \d(_\d)*. For example,

/resources/default/1_0/css/layout.css

To reference this resource, you would use:

<h:outputStylesheet library="default" name="css/layout.css" />

The library version will be appended as a v parameter in the query string of the generated <link> element.

<link type="text/css" rel="stylesheet" href="/contextname/javax.faces.resource/css/layout.js.xhtml?ln=default&amp;v=1_0" />

When you need to deploy an update, simply rename the subfolder from 1_0 to 1_1 or any other version (you can automate this process with ant). This way, the updated resource will be downloaded by the browser instead of using the cached one.

This versioning technique also applies to <h:outputScript> and <h:graphicImage> for JavaScript and image resources within JSF.
