Hi developers and experts, not sure if it's just me, I've got a fresh Code and the Yangster extension installed in my Windows 10 VM, with JDK 11.0.18. Syntax highlighting is fine when I open old Yang files. But when I create a new one there will always be errors popping out. Also other features like auto-complete are not working, so definitely something is not working well.

See if I need to provide more information for troubleshooting, thanks!

This is really strange YangSyncDiagramLanguageServer throws this exception because the service doesn't offer ISemanticHighlightingCalculator implementation, but it is registered in YangIdeModule.xtend https://github.com/TypeFox/yang-lsp/blame/master/yang-lsp/io.typefox.yang.ide/src/main/java/io/typefox/yang/ide/YangIdeModule.xtend#L115
Looks like io.typefox.yang.ide is not available.

@gavinchlam Is that a complete Java log? Which Java version do you have installed?

Hi @dhuebner, today I tried to open a new blank yang file in VS code and start putting something on it, and immediately a bunch of errors popping out:

I guess fundamentally something is not working well here. The Java version I installed is Java SE 11.0.18, and just to confirm, the VS code extension installed is version 2.2.

I was able to reproduce your issue with a file that has an uppercase letter in the file extension, e.g. test.Yang. Seems like a Case sensitivity issue.
I'm not able to test it with Windows, so could you please confirm that you are using .yang as file extension and the physical file effectively has this extension?
I will try to make yang-lsp to accept any case file extensions or at least provide a better error message.

Actually the moment I saved the file as a .yang file there aren't any errors prompting, and seems like whether it's "yang" or "Yang", it doesn't really matter. However, while I have syntax highlighting, key reference and problems reported if the syntax are not correct, I don't have auto-completion or suggestion. Do I have to enable anything? Meanwhile I will continue to monitor if there're still any errors coming out.

Thanks.
