#1295 PMDTask ClassNotFoundException with gradle

[Andrei Catinean]

Hello,

I am getting a ClassNotFoundException for net.sourceforge.pmd.ant.PMDTask when trying to create an ant task in gradle for the following line:

ant.taskdef(name: 'pmd', classname: 'net.sourceforge.pmd.ant.PMDTask')

This doesn't happen on 5.1.2

Please note, that with PMD 5.2.0 pmd has been modularized, so you'll need to add net.sourceforge.pmd:pmd-core as well as any language (e.g. net.sourceforge.pmd:pmd-java) in your dependencies list.

Does the documentation here http://www.gradle.org/docs/current/userguide/ant.html#useExternalAntTaskWithConfig describe what you want to do?

Then it would be for pmd >= 5.2 the following example:

configurations {
    pmd
}

dependencies {
    pmd(
        'net.sourceforge.pmd:pmd-core:5.2.2',
        'net.sourceforge.pmd:pmd-java:5.2.2'
    )
}

task check << {
    ant.taskdef(name: 'pmd',
                classname: 'net.sourceforge.pmd.ant.PMDTask',
                classpath: configurations.pmd.asPath)
    ant.pmd(shortFilenames: 'true',
            failonruleviolation: 'true',
            rulesetfiles: file('pmd-rules.xml').toURI().toString()) {
        formatter(type: 'text', toConsole: 'true')
        fileset(dir: 'src')
    }
}

Does this work for you?

I think that this is a gradle issue, not a PMD one. It should be fixed with Gradle 2.4, which will probably contains this commit here:

This seems to have been fixed with Gradle 2.4.
