How to install different version of jdtls

[arionrefat]

how can I install different version of jdtls? running the command LspInstall [email protected] doesn't work, it prompts with following error

config:

local servers = { "tsserver", "jsonls", "sumneko_lua", "pyright", "gopls", "jdtls" }

require("mason-lspconfig").setup({
	ensure_installed = servers,
	automatic_installation = { exclude = "jdtls" },
})

Hey! Try :MasonInstall [email protected].

Btw, ensure_installed and automatic_installation are independent of one another, and does different things. You can also include version numbers in the ensure installed list, like

ensure_installed = { "[email protected]" }

[williamboman]

Hm you probably are triggering the automatic installation? It should work just fine

[arionrefat]

sorry, this is my current config

I'm not using automatic_installation table

[williamboman]

Yeah so that will install jdtls (latest version) if it's not already installed when you open Neovim. I realize in my example I used the wrong version number, but hopefully the point went across anyway. :MasonInstall [email protected] works just fine for me. You can also use https://github.com/WhoIsSethDaniel/mason-tool-installer.nvim for automating this further

[arionrefat]

use https://github.com/WhoIsSethDaniel/mason-tool-installer.nvim

that helped, [email protected] is now installed

Thank you for your time <3

With newer jdtls versions it does not work. I tried :MasonInstall [email protected] and then it tries to download with a timestamp from the current release:

[codingluke]

@williamboman Thx for you answare!. I just tried ensure_installed = { "[email protected]" } and seeing another error. ...ker/start/mason.nvim/lua/mason-core/installer/linker.lua:43: bin/jdtls is already linked. I had an early version installed and removed it with :MasonUninstall jdtls can it be I have to clear something else too?

Ok I just solved it. there was still a file at ~/.local/share/nvim/mason/bin/jdtls I had to delete. Now it works with java 11 again :)

[williamboman]

Hm that shouldn't happen, it should be unlinked automatically. Do you have any ERROR logs in :MasonLog?

[codingluke]

Also here it was my own fault. I did not know :MasonUninstall jdtls at first and removed ~/.local/share/nvim/mason/packages/jdtls manually. However, I was not aware of ~/.local/share/nvim/mason/bin/jdtls.

A later :MasonUninstall jdtls did not remove ~/.local/share/nvim/mason/bin/jdtls. I guess it thought there is no jdtls installed anymore.

[williamboman]

Ah yes manually modifying file system will result in undefined behaviour :)
