PMD exclude-pattern with gradle - gradle

Question

I'm attempting to create some exclude patterns for a PMD task in Gradle.
My task is generated in the next way:
/* Allows generation of pmd config */
allprojects {
apply plugin: 'pmd'
}
gradle.projectsEvaluated {
subprojects.each() { project ->
if (project.hasProperty('android')) {
project.task("runPmd", type: Pmd) {
description "Run pmd"
group 'verification'
source = fileTree("${project.projectDir}/src/main/java")
ruleSetFiles = files("${project.rootDir}/build-tools/pmd.xml")
ignoreFailures = true
reports {
xml.enabled = true
html.enabled = true
}
}
}
}
}
And the ruleSet is:
<?xml version="1.0" encoding="UTF-8"?>
<ruleset name="MyCompany ruleset"
xmlns="http://pmd.sourceforge.net/ruleset/2.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://pmd.sourceforge.net/ruleset/2.0.0 http://pmd.sourceforge.net/ruleset_2_0_0.xsd">
<description>
MyCompany ruleset for Android PMD
</description>
<exclude-pattern>.*/org/jivesoftware/.*</exclude-pattern>
<exclude-pattern>.*/net/java/.*</exclude-pattern>
...rules...
</ruleset>
But in my reports, I'm getting:
Am I doing something wrong? Checking this answer seems that I'm defining the exclude-pattern right, but pmd is analyzing those files.

Answer 1

I was running into the same issue and adding an empty ruleSets [] property seemed to fix it for me.
Make sure to define the rules that you actually want to apply in your ruleset file - i.e. Move them from the ruleSet property block to the file (if you had any there).
This is what my task generation looks like:
// PMD
afterEvaluate {
def variants = plugins.hasPlugin('com.android.application') ?
android.applicationVariants : android.libraryVariants
variants.each { variant ->
def task = tasks.create("pmd${variant.name.capitalize()}", Pmd)
task.group = 'verification'
task.description = "Run PMD for the ${variant.description}."
task.ruleSetFiles = files("pmd-ruleset.xml")
task.ruleSets = []
task.reports {
xml.enabled = false
html.enabled = true
}
def variantCompile = variant.javaCompile
task.source = variantCompile.source
task.dependsOn(variantCompile)
tasks.getByName('check').dependsOn(task)
}
}
I got the hint from this thread:

Add below snippet in your build.gradle, you can exclude Classes and packages also
pmd {
sourceSets = [ project.sourceSets.main ]
ruleSetFiles = rootProject.files("codequality/pmd-ruleset.xml")
ruleSets = []
pmdMain {
excludes = [
'**/Application.*',
'**/jivesoftware/.*'
]
}
}

For my ruleset.xml for Gradle pmd plugin the following command works:
<ruleset name="Custom Rules">
<!-- Exclude generated open api classes -->
<exclude-pattern>.*/src/main/java/com/tbd/tbd/tbd/.*</exclude-pattern>
<exclude-pattern>.*/src/main/java/com/tbd/tbd/tbd/tbd/.*</exclude-pattern>
...
</ruleset>
Could you please try the command below?
...
<exclude-pattern>.*/src/main/java/net/java/.*</exclude-pattern>
...
