In the N4JS project, we want to explore the LSP feature of Xtext. For this reason, the mwe2 workflow was adjusted and we have the two files N4JSIdeModule and N4JSIdeSetup are present (containing no other code than the defaults). Also, I added a RunServer.java that contains a small main method to start an LSP server.
I populated the N4JSIdeModule with bindings from our existing N4JSUiModule. After starting the server, the console gives me some injection errors, which I understand to some extend. But before going through all injection bindings and errors, I'd like to get better understanding of the background of LSP support / ide packages in Xtext.
So, my questions (which overlap each other) would be:
- What is the general idea on ui and ide packages/dependencies?
- Is there some guide or help that I can read regarding separation of ui and ide, or what I need to consider when adding the LSP support?
- Can/should the (N4JS)IdeModule (transitivily) depend on ui packages of xtext or eclipse?
The stacktrace below indicates the problems of resolving/injecting the correct dependencies.
