There's an app written in Java & Kotlin. I'm running that in debug mode. The debugger gets attached correctly. If my breakpoint is set in Java code it's hit but any breakpoint in Kotlin code isn't. Why is that? How to make it work in IntelliJ?
Both types of sources reside in src/main.
Actually there is an answser to this question at StackOverflow. This might be marked as a duplicate of Intellij IDEA debugger not working on Gradle Vert.X project
