Could not find or load main class org.javacs.kt.MainKt

See original GitHub issue

Hi there,

Pardon my ignorance as I am completely new to the Java/Kotlin ecosystem and so understand very little about all the tools. I tried to search for similar issues but was unable to find anything which matched the exact problem I’m having. I will try to explain as much about my setup as possible so that it makes it easier for you to help me 😃

When I open a kotlin file in nvim using coc, I am unable to start KLS due to the following error:

[Error  - 5:51:04 PM] ~/Programs/kotlin-language-server/server/build/scripts/kotlin-language-server exited with code: 1
Error: Could not find or load main class org.javacs.kt.MainKt
Caused by: java.lang.ClassNotFoundException: org.javacs.kt.MainKt
[Error  - 5:51:04 PM] Connection to server got closed. Server will not be restarted.
[Error  - 5:51:04 PM] ~/Programs/kotlin-language-server/server/build/scripts/kotlin-language-server exited with code: 1

I set up a project by using https://start.spring.io/ and selecting Kotlin, Java 11, Gradle and Spring Boot 2.2.6 with the Web dependency.

I have also installed the Kotlin compiler separately and added it’s bin/ folder to my path so kotlinc is available.

I’m able to build the project using ./gradlew build and also run it successfully using ./gradlew bootRun.

If I run java -version on my machine I get the following output:

openjdk version "11.0.6" 2020-01-14
OpenJDK Runtime Environment (build 11.0.6+10-post-Ubuntu-1ubuntu118.04.1)
OpenJDK 64-Bit Server VM (build 11.0.6+10-post-Ubuntu-1ubuntu118.04.1, mixed mode, sharing)

Appreciate any help I can get as I would be really happy to continue using vim instead of switching to IntelliJ for a new Kotlin project that I will be a part of!
