PMD ruleset file

I am trying to figure where is the default ruleset file, name of the default ruleset file and how do we add our own rules to it. I tried to google, but that is just confusing me. S开发者_如何学编程o far, I have put the pmd plugin inside eclipse plugins folder and in preferences I can see PMD.

---

The standard ruleset file is *.xml inside pmd-bin-x.x.x.zip/.../lib/pmd-x.x.x.jar/rulesets/, refer to http://pmd.sourceforge.net/rules/index.html.

The default ruleset file of PMD Eclipse Plugin is inside pmd___.jar in your {IDE}/plugins/..., but you should not make any changes in that file. Add/edit the rules in Eclipse Preferences, any changes will take precedence over the default ruleset.

---

After messing with Ant and PMD for a good long while, this is the complete solution I have come up with. Modify to your own taste.

---

This sets the initial directories I use.

<property name="doc" location="doc" />               <!-- Root for all documentation: -->
<property name="pmddoc" location="${doc}/pmddoc" />  <!-- PMD results -->

---

This is my task definition, which points to the latest version of PMD at this time where I have it stored. It includes the PMD Jar itself (where all the rules are stored) and all PMD's dependencies as well.

<taskdef name="pmd" classname="net.sourceforge.pmd.ant.PMDTask">
    <classpath>
        <fileset dir="C:\development\pmd-bin-5.0-alpha">
            <include name="lib/*.jar"/>    <!-- also includes pmd's file, which has all the rulesets I need. -->
        </fileset>
    </classpath>
</taskdef>

---

In initialization, I create the documentation folder if needed:

<target name="init">
    <mkdir dir="${pmddoc}" />
</target>

---

...And finally, I created a target specifically for creating a PMD report in HTML form. Here it is.

<target name="pmd" depends="init">
    <pmd>
        <formatter type="html" toFile="${pmddoc}/pmd_src_report.html" toConsole="true"/>

        <ruleset>rulesets/java/basic.xml</ruleset> <!-- references file in PMD's .jar -->

        <!-- Files PMD will test. -->       
        <fileset dir="${src}">
            <include name="**/*.java"/>     <!-- required to avoid firing off .aj errors. This ruleset doesn't support AspectJ. -->
        </fileset>
    </pmd>
</target>
