IntelliJ not remembering Groovy SDK configuration

See http://stackoverflow.com/a/42518961/104891.

Unfortunately, didn't work. 

1. Deleted the project and imported the root build.gradle. 
2. Got the "Groovy SDK is not configured" message. 
3. Configured the SDK
4. Clicked the "Refresh Gradle project" to do what ./gradlew idea used to do.
5. "Groovy SDK not configured" message is back.

Delete .idea directory, iml and ipr files, edit build.gradle to include Groovy dependency, reimport the project from build.gradle.

For future readers, this was solved by adding these two lines to my root gradle file.

Hi there,
I had a similar issue but with simple java project. Thanks to Twilcock's answer I figured out how to fix this issue. Just modify build.gradle like next:

sourceSets {
    groovyUtils
}

dependencies {
    groovyUtilsCompile 'org.codehaus.groovy:groovy-all:2.5.1'
    groovyUtilsCompile 'org.apache.ivy:ivy:2.4.0'
}

(I added 'org.apache.ivy:ivy:2.4.0' dependency as well in order to use @Grab annotations).

Refresh gradle project and then in your Run/Debug Groovy configuration select Module = <projectName>_groovyUtils.

Here is what worked for me, hopefully it will help someone else:

I completed wiped the     ~/.cache/JetBrains directory. 

So which dependencies should I add in a Java only project that has Groovy Jenkinsfile?
