A category.xml file can be used to include content into a p2 repository and to specify how to display the content in the p2 installation dialog. For it to be used by a Tycho build, it needs to be placed into the root of an eclipse-repository project.

The category.xml format was originally defined by the Eclipse PDE project. There are extensions to the format only supported by p2 and Tycho.

Format overview

Stub category.xml file:

<?xml version="1.0" encoding="UTF-8"?>
<site>
   <feature id="feature.id" version="1.4.100.v2009"/>
   <bundle id="bundle.id" version="1.3.1.v2013"/>
   <iu id="unit.id"/>
   <iu>
     <query> 
       <expression type="match">
         <![CDATA[
           id == $0
         ]]>
       </expression>
       <param>another.unit.id</param>
     </query>
   </iu>

   <feature id="feature.in.category">
      <category name="category.id"/>
   </feature>
   <category-def name="category.id" label="Category Label">
      <description>Details on the category</description>
