Maven pdf plugin: Where to put userconfig.xml

Question

Due to some special characters in my language, I need to embed font into PDF file. I read a lot of pages about FOP, and I figured out I need configuration file like this:

<?xml version="1.0"?>
<fop>
  <renderers>
    <renderer mime="application/pdf">       
      <fonts>                           
            <font kerning="yes"  embed-url="file:///C:/windows/fonts/arial.ttf">
                  <font-triplet name="Arial" style="normal" weight="normal"/>
                </font>                     
        </fonts>
    </renderer>
  </renderers>     
</fop>

Unfortunatelly, when I run mvn pdf:pdf -X, I see line

[DEBUG] userconfig is null

Which looks like the config is loaded. Where should I put the configuration file and how I can tell the pdf plugin, where to look?

Answer 1

I found out the sollution, but still I am not convinced that it is ideal. I used Exec Maven Plugin and run the fop with the result created from Maven Pdf Plugin. The final solution looks like:

pom.xml

                  <argument>.\target\pdf\fop.xconf</argument>

      </dependency>
   </dependencies>
</project>

fop.xconf:

<?xml version="1.0" encoding="UTF-8"?>
<fop>
   <renderers>
      <renderer mime="application/pdf">
         <fonts>
            <font kerning="yes" embed-url="file:///C:/windows/fonts/arial.ttf">
               <font-triplet name="Arial" style="normal" weight="normal" />
            </font>
         </fonts>
      </renderer>
   </renderers>
</fop>

fop.xconf is stored in site/resources next to pdf-config.xml and it is copied into target by maven pdf plugin.
