spending 1-2h hours happened only on my second project, when I had the first as the blue print. The first time with only the documentation I failed the first day. Luckily another user of this forum agree to help me! I shared my screen and together with his help we got my project configured to also allow Kotlin 🙇♂️
But since I'm going to hold a presentation on this topic in two weeks time, I thought, I better double check if I now understand the steps correctly so I wrote a dummy project with only java, java/kotlin and only kotlin -config. and a blog post to come with it 🙂
