-- 1. get the config for this server from nvim-lspconfig and adjust the cmd path.
--    relative paths are allowed, lspinstall automatically adjusts the cmd and cmd_cwd for us!
-- local config = require("lspconfig").jdtls.document_config
-- require("lspconfig/configs").jdtls = nil -- important, unset the loaded config again
-- config.default_config.cmd[1] = "./node_modules/.bin/bash-language-server"

-- 2. extend the config with an install_script and (optionally) uninstall_script
-- require'lspinstall/servers'.jdtls = vim.tbl_extend('error', config, {
--     -- lspinstall will automatically create/delete the install directory for every server
--     install_script = [[
--       git clone https://github.com/eclipse/eclipse.jdt.ls.git
--       cd eclipse.jdt.ls
--       ./mvnw clean verify
--   ]],
--     uninstall_script = nil -- can be omitted
-- })

-- require'lspinstall/servers'.kotlin = vim.tbl_extend('error', config, {
--     install_script = [[
--       git clone https://github.com/fwcd/kotlin-language-server.git language-server
