Description

Loading any .kt file yields this error:

[coc.nvim] Kotlin Language Client client: couldn't create connection to server.

Extension version

0.0.9

Additional context

This happens on both MacOS and Linux. This was working before (in the same projects) a few weeks ago, so something seems to have changed.

After confirming the prompt to auto-download the Kotlin language server, I get this:

Description

coc-kotlin fails to start & I don't see any auto completions even after waiting for 10-15 mins.

Extension version

Latest version of coc-kotlin as I just reinstalled it

Additional context

Here is what :CocCommand workspace.showOutput says

Try using kotlin-language-server directly works
I tried removing coc-kotlin & since it uses kotlin-language-server it works for me!

I cloned & built kotlin-language-server from it repository & added the following in my :CocConfig

    "languageserver": {
        "kotlin": {
            "command": "~/Downloads/workspace/dotfiles/kotlin-language-server/server/build/install/server/bin/kotlin-language-server",
            "filetypes": ["kotlin"],
            "trace.server": "verbose"
        }
    }

The same worked, but I had to wait for 3-5 mins before it starts & have to keep an eye on my workspace.showOutput to know when it's ready to use, so not very convenient. I think coc-kotlin uses this language server under the hood & provide helpful info like the state of plugin & building it etc.

Would you be able to help me debug what the issue might be?

Launching server "kotlin" failed

Result from CocInfo

Description

Launching server "kotlin" failed

Extension version

0.0.6

Additional context

If I config the language server by using coc langaugeserver config like

"languageserver": {
    "kotlin": {
      "command": "/home/wexder/.config/coc/extensions/coc-kotlin-data/langServerInstall/server/bin/kotlin-language-server",
      "filetypes": ["kotlin"]
    }
  }

it works.

JDK isn't correctly detected

Result from CocInfo

Description

A clear and concise description of the bug and how to reproduce it.

I have openjdk-8-jdk installed and JAVA_HOME set, but coc-kotlin cannot detect it and keep giving warnings:

JAVA_HOME: /usr/lib/jvm/java-8-openjdk-amd64/jre

Description

I want to solve competitive programming tasks with Kotlin. I don't want to create multi-file projects, just one file containing all the code. I have a competitive-programming-task-Kotlin template that I used with Intellij, and it used to work. When I open this template in Vim, I get the error: "ERROR Unresolved Reference: readLine." I will provide the code for the template in the "Additional Context" section below.

Extension version

v0.0.7

Additional context

Template Code

fun main(){

}

// Input
private fun readInt() = readLine()!!.toInt()
private fun readInts() = readLine()!!.split(" ").map { it.toInt() }
private fun readLong() = readLine()!!.toLong()
private fun readLongs() = readLine()!!.split(" ").map { it.toLong() }
private fun readFloat() = readLine()!!.toFloat()
private fun readDouble() = readLine()!!.toDouble()
private fun readString() = readLine()!!
private fun readStrings() = readLine()!!.split(" ")
