Settings not taken into account

[greg0ire]

I can see this error on some lines:

Cannot inline bytecode built with JVM target 11 into bytecode that is being built with JVM target 1.8. Please specify proper '-jvm-target' option [INLINE_FROM_HIGHER_PLATFORM]

I've seen #72, so I tried to fix it like this:

require("mason-lspconfig").setup_handlers {
    function (server_name) -- default handler (optional)
      if server_name == "kotlin_language_server" then
        require("lspconfig")["kotlin_language_server"].setup {
          on_attach=custom_lsp_attach,
          capabilities = require('cmp_nvim_lsp').default_capabilities(),
          settings = {
            kotlin = {
              compiler = {
                jvm = {
                  target = "11"
                }
              }
            }
          }
        }
      end
      require("lspconfig")[server_name].setup {
        on_attach=custom_lsp_attach,
        capabilities = require('cmp_nvim_lsp').default_capabilities()
      }
    end,
}

That does not seem to have any effect. How do I troubleshoot this?

Could you test if it works in VSCode? Just to rule out that it's not an editor/client-specific issue.

[greg0ire]

I am unfamiliar with VS Code but I installed it (pacman -S code), and then I installed this, but I don't have the INLINE_FROM_HIGHER_PLATFORM. Instead, I have a lot of UNRESOLVED_REFERENCE, for types that come from dependencies it seems.

[fwcd]

Then the language server may have trouble finding your dependencies. Try a vanilla Gradle or Maven project, if that works, try finding the differences to your project.

[greg0ire]

Ah I just saw that the page for the extension mentions that it must be a Maven or Gradle project. I'm using Gradle, but I guess I must also install a Gradle extension for vscode? I'm installing the "Gradle for Java" extension

[fwcd]

In principle Kotlin should suffice

[greg0ire]

I'll try with https://github.com/fwcd/kotlin-quick-start then

Step 1: finding the right openjdk version for it. It does not seem to be openjdk-21:

General error during conversion: Unsupported class file major version 65

EDIT: v17 seems to build. Step1 done.
Now trying to reproduce the INLINE_FROM_HIGHER_PLATFORM issue.

Step2: reproducing the Neovim: ✔️
I installed mockito 5.0.0 (testImplementation("org.mockito.kotlin:mockito-kotlin:5.0.0")), then edited a test to add
private val appMock: App = mock()

Step3: reproducing the issue with VSCode ✔️

Step 4: changing the setting in VSCode ✔️

[greg0ire]

Changing the setting VSCode fixes the issue, so it would seem the issue is Neovim-specific. It would be great if there was a way for me to see what settings Neovim sends to kotlin-language-server.

EDIT: here is what I get when I type :LspLog in Neovim:

OK… I am stupid 🤦

 require("mason-lspconfig").setup_handlers {
     function (server_name) -- default handler (optional)
       if server_name == "kotlin_language_server" then
         require("lspconfig")["kotlin_language_server"].setup {
           on_attach=custom_lsp_attach,
           capabilities = require('cmp_nvim_lsp').default_capabilities(),
           settings = {
             kotlin = {
               compiler = {
                 jvm = {
                   target = "11"
                 }
               }
             }
           }
         }
+          return
       end
       require("lspconfig")[server_name].setup {
         on_attach=custom_lsp_attach,
         capabilities = require('cmp_nvim_lsp').default_capabilities()
       }
     end,
 }

Thanks for your answers, and great work with this LSP!

Glad to hear you fixed it!
