Hello,
I would like to retrieve the client configuration from my xtext language server.

When I call LanguageClient.configuration(...) on server side I get a org.eclipse.lsp4j.jsonrpc.ResponseErrorException: Unhandled method workspace/configuration.

It seems not implemented.

Any idea on how to solve this issue ?

Subclass languageserverimpl. Handle it. Bind subclass in serverModule or mixin for in. Create custom launcher class with new module

Thanks for your answer.

My current design match to what you said. In fact it seems not possible to call the client.configuration(...) during LanguageServer.Initialize(...). I will delay the call later.

In fact my need is to configure a list of project dependencies in VS Code configuration:
"configuration": [
			{
				"type": "object",
				"title": "MyDsl",
				"properties": {
					"mydsl.dependencies": {
						"type": "array",
						"scope": "resource",
						"item": "string",
						"default": [
							"mydsl_common_library"
						],
						"description": "Project dependencies:"
					}
				}
			}
		]


On Xtext side I would like to retrieve this list and store the dependencies in a specialized IProjectConfig and to create a ProjectDescription with a populated list of dependencies. After I will have to create a custom IAllContainerState to link the dependencies with the provided VSCode workspace folders.

Is it a correct approach ?

i am not sure. you need to try out.
native question?
why not store project setup in a special file in workspace?
how do you handle the deps clientside?

can you have a look at the didChangeWorkspaceFolders and didChangeConfiguration impls?

My initial idea was to reuse the VSCode configuration to reuse its editor. But this solution is platform dependent and I prefer now have a custom configuration file for my DSL.

My json configuration file contains the list of project dependencies. When the configuration files is changed I notify the server:
    context.subscriptions.push(
        workspace.createFileSystemWatcher('**/.mydsl/settings.json').onDidChange(() => {
            lc.sendNotification(`workspace/didChangeConfiguration`, undefined)
        })
    );

and on Server side I update the project config and run a new build in case the configuration changes.

I still have some issues with project cross references. When I change a dsl in project A, changes are not reflected in the index of project B(with dep on A).

i assume you need to debug affected calculation / project / workspace manager (e.g. org.eclipse.xtext.build.Indexer)
