Import the headless-services modules into your workspace as existing Maven projects.
Startup the Boot Language Server with:
Main Class: org.springframework.ide.vscode.boot.app.BootLanguageServerBootApp (or a corresponding class for other language servers)
Vmargs: -Dstandalone-startup=true
This starts up the language server and it listens on port 5007
Use STS or a dedicated instance of VSCode to launch org.springframework.ide.vscode.boot.app.BootLanguageServerBootApp in run or debug mode (or another Language Server app)
@ Connect local Spring Tools Java LS to VSCode
You should run the extension from vscode as a 'runtime workbench' with some small changes.
Start by opening the extension for the server you want to work on in vscode:
$ cd vscode-extensions/vscode-spring-boot
$ ./build.sh
$ code .
Open Main.ts and change:
CONNECT_TO_LS: true
Save, then launch by pressing F5.
This connects the VSCode extension to the locally running language server. It also uses port 5007
Startup Eclipse or the Spring Tools for Eclipse distriution. I.e something that support for RCP / plugin development.
Define a recent nightly Spring Tools for Eclipse build as your target platform.
Import the projects under eclipse-language-servers into your workspace.
Startup a runtime workbench of the Spring Tools for Eclipse distribution
The language server plugin is: org.springframework.tooling.boot.java.ls
Add Vmargs: -Dboot-java-ls-port=5007
This lets the Eclipse language server extension connect to the locally running language server on port 5007

Generic editor source code (used by lsp4e as a dependency): https://github.com/eclipse/eclipse.platform.text Not sure which version of this you should checkout, it probably depends on your version of Eclipse as this is part of the eclipse platform.
-
LSP4E source code: clone git repo at https://github.com/eclipse-lsp4e/lsp4e and import the projects into your workspace.
-
LSP4J source code: Add the LSP4J-SDK feature to your target platform. We have usually versions from this in our builds: http://services.typefox.io/open-source/jenkins/job/lsp4j/job/master/lastStableBuild/artifact/build/p2-repository/
