Gradle PMD – Can’t find resource null

Gradle has support for PMD. You can find following example on internet:

apply plugin: 'pmd'

pmdMain {
  ruleSets = [ "basic", "strings" ]
}

This code is not working with Gradle 2.0. Here is error message:

:clean
:pmdMain FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':pmdMain'.
  Can't find resource null. Make sure the resource is a valid file or URL and is on the CLASSPATH. Here's the current classpath: C:\Users\georgik\tmp\install\gradle-2.0\lib\gradle-launcher-2.0.jar

The reason is simple. In case of Gradle 2.0 you must add language prefix before name of rule. You must use java-strings instead of plain strings.

Here is correct example (available also on YSoftDevs Github):

apply plugin: 'pmd'

pmdMain {
  ruleSets = [ "java-basic", "java-strings", "java-braces" ]
}

You can find more rules for PMD in official documentation.

Thanks Matt Sicker for correct solution.

How to debug Gradle script

First of all: do not use daemon mode for debugging.

IntelliJ Idea is automatically spawning daemon when you start any Gradle task. You have to attach to remote process.

I wrote small “How to debug” based on info from forums.gradle.org.

You’ll need to set GRADLE_OPTS environment variable to:

-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=5005

Here is example in PowerShell:

01-command-line-options

$env:GRADLE_OPTS="-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=5005"

Configure Remote debugging in Idea:

02-configure-remote

You do not need to change anything in default configuration.

Now return to command line with your project and invoke task. Gradle will automatically stop and it waits for debugger.

03-start-process

Attach debugger

04-attach-to-process

Here we go 🙂

05-break-point

There is small limitation. You can stop code execution outside DSL e.g. in class method (line 3). You won’t be able to stop execution in Gradle DSL line 10.

You can download sample build script from Github.

Gradle Summit 2014 Lightning talk: Bamboo + Gradle

I had an opportunity to be one of Lightning talks speakers at Gradle Summit 2014 in Santa Clara – California.

I’d like to share with you slides from my talk about Bamboo and Gradle integration which we successfully deployed in Y Soft.

Link to Speaker Deck

It was exciting to hear about experience with Gradle from other speakers from companies like Netflix, Prezi or JFrog.
