#1274 ant integration broken with pmd-5.2.0

[James Jamieson]

When parsing rules using Ant, an Illegal Argument Exception is given even though the language attribute is correctly set for this rule in the pmd-java-5.2.0.jar.

java.lang.IllegalArgumentException: Unknown Language 'java' for Rule JumbledIncrementer, supported Languages are

In addition, adding the sourceLanguage attribute to the Ant tasks produces a different error:

The following language is not supported:<language name="java" version="1.6">.</language>

[Andreas Dangel]

Thanks for testing the new version!

It seems like the classpath doesn't contain all necessary pmd jars (at least pmd-core-5.2.0.jar and pmd-java-5.2.0.jar are required).

Do you have something like this in your ant build.xml file?

<path id="pmd.classpath">
    <pathelement location="${build}"/>
    <fileset dir="/path/to/my/pmd/lib/">
        <include name="*.jar"/>
    </fileset>
</path>

<taskdef name="pmd" classname="net.sourceforge.pmd.ant.PMDTask" classpathref="pmd.classpath"/>

[James Jamieson]

I do and both jars are in the fileset location

Snippet from build file:

<path id="pmd.classpath">
    <fileset dir="${pmdLib.dir}">
        <include name="*.jar"/>
    </fileset>
</path>

<taskdef name="pmd" classname="net.sourceforge.pmd.ant.PMDTask" classpathref="pmd.classpath"/>

[Andreas Dangel]

Well, for now, you'll need to specify the classpath from outside when running ant:

ant -lib /your/path/to/pmd/lib/

This will add all the pmd jars to the classpath.

That worked, specifying them directly in the command line for ant allowed 5.2 to run without issue. Hopefully this can be fixed in a future release!
