Using a custom PMD ruleset file within Ant [closed]

Question

I'd like to use a custom PMD ruleset file for my build. Basically, I want to use many of the built-in ruleset packages with some rules turned off.

For example, suppose I only wanted the strings and basics rules, I have this ruleset file, called ruleset.xml:

<?xml version="1.0"?>
   <ruleset name="Custom ruleset"
       xmlns="http://pmd.sf.net/ruleset/1.0.0"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://pmd.sf.net/ruleset/1.0.0 http://pmd.sf.net/ruleset_xml_schema.xsd"
    xsi:noNamespaceSchemaLocation="http://pmd.sf.net/ruleset_xml_schema.xsd">
     <description>
     This ruleset checks my code for bad stuff
  </description>
  <rule ref="rulesets/strings.xml"/>
  <rule ref="rulesets/basics.xml"/>

</ruleset>

And then I include a reference to that file in my Ant task, like so:

<target name="pmd"
           description="Analyzes our source code for violations of good Java">
      <pmd shortFilenames="true" failuresPropertyName="failures.count" 
           rulesetfiles="ruleset.xml">

         <formatter type="xml" toFile="${build.home}/pmd.xml" />
         <fileset dir="src">
            <include name="**/*.java" />
         </fileset>
      </pmd>
      <echo message="PMD detected ${failures.count} violations" />
      <xslt in="${build.home}/pmd.xml" 
         style="tools/pmd/etc/xslt/pmd-report.xslt" 
         out="${build.home}/pmd.html" /> 

   </target>

This fails with the following exception:

BUILD FAILED E:\build.xml:120: java.lang.RuntimeException: Couldn't find that class Can't find resource rulesets/basics.xml. Make sure the resource is a valid file or URL or is on the CLASSPATH at net.sourceforge.pmd.RuleSetFactory.parseRuleSetNode(RuleSetFactory.java:229) at net.sourceforge.pmd.RuleSetFactory.createSingleRuleSet(RuleSetFactory.java:135) at net.sourceforge.pmd.RuleSetFactory.createRuleSets(RuleSetFactory.java:85) ...

Basically, the ruleset xml file breaks the classpath for the task. I've tried adding a classpath element to the pmd task, but that doesn't work.

What do I have to add to get my custom ruleset file to work? I'd prefer to add something to the ant file, rather than the ruleset file.

Doh! Writing this out on SO helped debug my issue. The problem was that there is no basics.xml, it's called basic.xml. Fix the typo and everything runs just fine.
