I’m noticing that there are some issues with using Gradle 1.9 with Intellij 13… as far as I can tell they only appear when old bits of old configurations (from Intellij 12, Netbeans, or Gradle 1.8) are lying around. In order to get things working I did the following.
Careful if you follow these steps… consider moving the files instead of deleting them if you don’t know whether you need them. I know I didn’t need them for anything and they are automatically recreated by gradle or the ide.
gradle clean cleanIdea
rm -rf .idea
rm -f *.iml
rm -rf .gradle
rm -rf build # was necessary for me, but probably not for you
rm -f build.xml # left over Netbeans auto generated build
rm -rf nbproject
./gradlew idea
Then I opened Intellij and opened the project (I didn’t import, I opened).
