Using the KLS with a spring project + mvn + launching within remote docker container

I really love using the remote docker container extension so I don't have to install all of these runtimes on my host PC. I'm wondering if this is causing the issue. But essentially I've started a boilerplate spring rest api using kotlin and added the fwcd kls. It's not able to resolve any imports at all. Attaching image below as well as the relevant repo. Any help is greatly appreciated.

Edit: I updated the dev container docker file to install kotlin in the remote container as I think I was missing this. But still getting the same unresolved errors.
```
RUN su vscode -c "umask 0002 && . /usr/local/sdkman/bin/sdkman-init.sh && sdk install kotlin"
```

Start with the linked weather-service repository and its remote container configuration, then reproduce the unresolved imports while launching the Kotlin language server in the container. Compare the Kotlin, Spring and Maven project setup with the language server's environment; done means the Spring project's imports resolve in the remote container.
