Generated Language template contains compilation errors

[agonzalezgaliana]

Currently investigating how to create a Theia Language Server plugin. I found this generator by following the tutorial from EclipseSource. However the resulting code has compilation issues (most likely because of newer changes included in Theia).

By taking a look to this thread I decided to open an issue here.

The following is what I've done so far:

Use the generator plugin to create a language example via yo @theia/plugin.
The generated code includes some compilation errors in the (in my case) language-backend.ts:

Namespace '"@theia/plugin"' has no exported member 'LanguageServerInfo'.
Property 'languageServer' does not exist on type 'typeof import("@theia/plugin")'.

Were those elements (LanguageServerInfo, languageServer) replaced by others?

Many thanks in advance
