Usage

With PMD Gradle plugin

Add PMD plugin:

build.gradle

apply plugin: 'pmd'
pmd {
    // pmd plugin config
}

Add this library to the PMD classpath:

build.gradle

sourceSets {
    pmd
}
dependencies {
    pmdRuntime 'io.github.juliantcook:pmd-rules:0.0.1'
}
// set classpath for appropriate PMD tasks
tasks.pmdMain.doFirst {
    pmdClasspath += sourceSets.pmd.runtimeClasspath
}

These rules can then be used.
