Language server reports diagnostics for source archives

[JulianVennen]

Hey, I started working on a plugin for JetBrains that uses this LSP: https://github.com/JulianVennen/spyglass-mc-jetbrains

While working on that, I noticed numerous errors in my IntelliJ log that looked something like this:

2025-02-04 18:47:42,428 [  10441]   WARN - #c.i.p.l.a.LspServerDescriptor - Unexpected URI scheme: archive://vanilla-mcdoc.tar.gz/java/server/world/entity/mob/breedable/tamable.mcdoc

After enabling debug logging which outputs all LSP messages, the following appeared:

2025-02-04 18:47:42,428 [  10441]   FINE - #c.i.p.l.i.c.Lsp4jServerConnector - <-- SpyglassLspServerDescriptor@towers: {"jsonrpc":"2.0","method":"textDocument/publishDiagnostics","params":{"diagnostics":[],"uri":"archive://vanilla-mcdoc.tar.gz/java/server/world/entity/mob/fish.mcdoc"}}

Spyglass appears to be reporting diagnostics for files inside the vanilla-mcdoc.tar.gz and mcmeta.tar.gz. Obviously, files inside these are not part of the project I have opened in my IDE, so it makes sense that IntelliJ logs an error in that case.

It would be best to discuss this on Discord, are you available there?

Really cool that someone is working on an Intellij plugin! I'm guessing this is something specific to the intellij LSP client implementation, because I've definitely seen diagnostics for these archives reported in vscode.

That said, I guess it doesn't really make sense to have these reported in the workspace, and there have been questions from users whenever there are stray diagnostics in some of the vanilla-mcdoc files for example. So it'd probably be best to filter these out in the Spyglass language server based on the URI scheme.
