Pass custom code style xml to gradle idea plugin

Question

Is there any way to tell the gradle idea plugin to use a custom code style xml when generating the project's files?

I can always copy the xml into "~/Library/Preferences/IntelliJIdea13/codestyles" and then change the code style once I import the project but I would like the gradle plugin to do this automatically for me as part of its generation.

Thanks!

Just in case someone else is trying to do this, I managed to solve it using the plugin hooks to modify the project's ipr file before it gets written to disk. Basically, adding the following to your build.gradle:

idea {
  project {
    ipr {
      withXml { provider -> addCodeStyle(provider) }
    }
  }
}

  def addCodeStyle(provider) {
      def project = provider.asNode()
      project.appendNode('component', [name: 'ProjectCodeStyleSettingsManager'])

      def codeStyleNode = findComponent(project, 'ProjectCodeStyleSettingsManager')
      codeStyleNode.appendNode('option', [name: 'USE_PER_PROJECT_SETTINGS', value: 'true'])
      def projectSettingsNode = codeStyleNode.appendNode('option', [name: 'PER_PROJECT_SETTINGS']).appendNode('value')    

      def codeStyleUrl = "fileUrl".toURL()

      //If you want to read from a file you could do new File(path).text
      def codeStyleXml = new XmlParser().parseText(codeStyleUrl.text)
      codeStyleXml.children().each { option ->
          projectSettingsNode.append(option)
      }
  }

This assumes that your xml with the code style preferences follows the format:

<?xml version="1.0" encoding="UTF-8"?>
<code_scheme name="X">
  <option name="CLASS_COUNT_TO_USE_IMPORT_ON_DEMAND" value="6" />
  <option name="NAMES_COUNT_TO_USE_IMPORT_ON_DEMAND" value="9" />

Which I think is the standard format when you export your preferences from IntelliJ.
