Build File testing Gradle Grails Plugin

testGradleGrailsPlugin.gradle

/*
  In Windows, running "$gradle test" results in error: "Could not find or load main class org.grails.launcher.Main"
  I discovered the plugin was escaping spaces in paths to GRADLE_USER_HOME with %20; i.e. 
  -cp C:\Users\FirstName%20LastName\.gradle\caches\modules-2\files-2.1\org.grails\grails-launcher\1.1\...\grails-launcher-1.1.jar
  
  This caused the classpath not to be properly set, resulting in the error.
  
  I blogged about this issue at: http://jackfrosch.com
