I’d like to start contributing to kotlin, any advice?

Check out #kontributors , but also see the contribution part of the README on the github repo. There's some good advice. Great starter tasks can be documentation fixes or code samples, just to get used to building and contributing to the project.

is there any documentation on the kotlin project structure?

I'm not sure what you mean? If you have questions about where to find things you can probably post in #kontributors or make use of the IntelliJ search features.

tnx

We need some maven plugins to build our maven plugin ¯\_(ツ)_/¯

i always thought that gradle replaces maven
