# gradle

In Intellij, at the top of all my build.gradle.kts files, there is a pink banner which says Unable to find Gradle home directory. I have a couple of modules with Groovy build.gradle files and they don't show this message. Have I done something wrong? I'm using the Gradle wrapper. Is this not something that the Kotlin DSL can deal with?
