Example 4 with LanguageServer

use of org.eclipse.lsp4j.services.LanguageServer in project sts4 by spring-projects.

the class LaunguageServerApp method startAsServer.

 * instead of connecting itself to an existing port or channel.
 *
 * This is meant for development only, to reduce turnaround times while working
 * on the language server from within an IDE, so that you can start the language
 * server right away in debug mode and let the vscode extension connect to that
 * instance instead of vice versa.
