Issues with multiple servers after upgrading languageclient to 4.1.3 #65
Description
Currently tracked in microsoft/vscode-languageserver-node#333.
After upgrading vscode-languageclient from 3.5.0 to 4.1.3, we are having problems with multiple spawned language servers, which is needed for multi-root support. I want to note that this works in 3.5.0, and some breaking change was introduced (or errors were made non-silent) in 4.x.
The error comes from hie giving back its capabilities on initialization, where it registers executeCommandProviders. When a second server gets spawned, this command already exists, and VSCode then complains about this.
