A modern programming language that makes developers happier.

kotlinlang

when a class in a plugin.xml file does not exist idea offers to create that class and even has it implement the correct interface. but its always creating java classes. Is there a setting to create kotlin classes instead?

You mean in a custom IDEA plugin? Probably it's not possible, please consider creating a feature request at <https://youtrack.jetbrains.com/issues/IDEA>

yes, when writing an idea plugin. i thought that its really strange because the plugin demo project contains only kotlin sources, and still idea creates a java file per default
