Testing out Gradle (and Groovy). When I do a “gradle clean build” it fails, encouraging me to submit a report here 
Root cause seems to be: “Caused by: org.gradle.cache.internal.btree.CorruptedCacheException: Corrupted IndexBlock 6198 found in cache ‘/Users/stoyle/projects/repos/km-groovy-testing/.gradle/1.8/taskArtifacts/outputFileStates.bin’.”
All details, gradle build file, groovy test file and build output can be found here: https://gist.github.com/stoyle/a3507c90bc2c51b420b5
On MacOSX 10.8.5, Gradle 1.8, Groovy 2.1.7. Testing with IntelliJ 12.1.4.
All I did was to paste some code into the Greet.groovy file, and rename the Greet class to Greet1, since the Groovy compiler complained.
Workaround was to remove the .gradle folder.
Cheers, Alf
