Extension fails on Ubuntu devcontainer - couldn't create connection to server. about kotlin-language-server HOT 3 OPEN

Found this repo https://github.com/alexanderhansen/vscode-remote-try-kotlin, everything works when I create a codespace from it. What is his repo doing right that mine is not?

from kotlin-language-server.

Caused by: org.javacs.kt.util.KotlinLSException: No repositories found at $MAVEN_REPOSITORY, $MAVEN_HOME, $M2_HOME or $HOME/.m2` seems most relevant.

looks suspicious, the SLF4J stuff is fine (should probably add a troubleshooting entry on that). We probably should not be throwing an exception if we cannot find a local Maven repository (maybe make it optional instead?):

https://github.com/fwcd/kotlin-language-server/blob/7dd4680017d7f04f621fbb952988a78b7dca581e/shared/src/main/kotlin/org/javacs/kt/classpath/Home.kt#L20C14-L24

Note that support for non-Gradle/Maven projects isn't great yet, mostly because there are so many different ways Kotlin and its standard library could be packaged.

I am also running into this error when attempting to use this plugin inside of a dev container with VSCode. I am using eclipse-temurin:17-jdk-jammy as a base image.

Here is the relevant output from the console:
