how do i set up modules in IntelliJ ? I rightclicked the mainproject and added a module from there but the module has no source folder by default and when I create it manually it doesnt give me the presets for creating kotlin files ect (and when i create those manually as well i dont have any syntax highlighting, code completion ect)

Did you select “Kotlin” type when you added the module? Maybe even better: Take a step back and explain what you are trying to do. If I just want to quick start a simple Kotlin app for experimentation, I usually do “gradle init --type=kotlin-application”

i selected Gradle -> Kotlin/JVM as the project type as i always do when creating a new project

When you have a gradle project, IDEA will not help you to create a new module, AFAIK. Create a new directory for your new module, create a build.gradle(.kts) in that module, include the new module in your settings.xml and re-import into IDEA.

it does

Well, live and learn.

yes, it added a line

include 'server'

Ok, I just tried it: Strangely, IDEA briefly modifier the settings.gradle, but then removed the line again. I re-added it, re-imported and then got an error because IDEA added the version info to the plugin declaration in the new submodule: id ‘org.jetbrains.kotlin.jvm’ version ‘1.3.50’ That does not work of course, because the version is already set in the root project. I removed that version and re-imported and everything seems to work.

i too had the problem with the version and aready figured out how to fix it, but unfortunately that doesnt fix the mising kotlin ide integration#

Hm, strange. And you are sure that you created the correct folder structure “server/src/main/kotlin”?

i went to bed and the next morning it just worked without changing anything ¯\_(ツ)_/¯
