Known LSP Servers for Copilot CLI

Reference data for the lsp-setup skill. Each section contains install commands per OS and a ready-to-use config snippet.

Config snippet format: Each snippet below shows the object to insert as a value under the top-level lspServers key. A complete config file looks like: { "lspServers": { <snippet here> } }. When adding multiple languages, merge their snippets as sibling keys under lspServers.

Java

Server: Eclipse JDT Language Server (jdtls)

Requires Java 21+ on JAVA_HOME or $PATH.

Install

OS	Command
macOS	brew install jdtls

On macOS with Homebrew, the binary is installed as jdtls on $PATH.
