Groovy Codenarc.xml org.xml.sax.SAXParseException xsi:schemaLocation not associated with element type ruleset not bound

Question

I'm using Gradle 2.3 and project has Groovy code. For static code analysis, I'm using Codenarc (i.e. project folder has "config/codenarc/codenarc.xml" file).

In the build.gradle / GRADLE_HOME/init.d/top-level.gradle file, I have:

apply plugin: 'codenarc'

   codenarc {
     ignoreFailures = true
     configFile = file("config/codenarc/codenarc.xml")
   }

But while compiling this project, I'm getting the following error.

13:49:00 :codenarcAcceptanceTest UP-TO-DATE
13:49:01 :codenarcIntegrationTest FAILED
13:49:01 
13:49:01 FAILURE: Build failed with an exception.

File contents in codenarc.xml file are:

The xml did not know what xsi is you have add this as prefix from the correct namespace url. Try the following header:

<ruleset xmlns="http://codenarc.org/ruleset/1.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://codenarc.org/ruleset/1.0 http://codenarc.org/ruleset-schema.xsd"
    xsi:noNamespaceSchemaLocation="http://codenarc.org/ruleset-schema.xsd">
