Problem

On IntelliJ startup, the plugin throws a PluginException wrapping a NullPointerException because the doseq loop in RegisterActionsStartup iterates over clojure-lsp-commands and passes :keyboard-shortcut keyboard-shortcut unconditionally to action/register-action!. Commands that don't define a keyboard shortcut (most of them) have nil here, which violates IntelliJ's @NotNull contract on KeymapImpl.addShortcut.

Fixes #84

Solution

Wrap the call with apply and use cond-> to only include :keyboard-shortcut in the args vector when it is non-nil:

(apply action/register-action!
  (cond-> [:id ... :title text ...]
    keyboard-shortcut (conj :keyboard-shortcut keyboard-shortcut)))

This way commands without a shortcut are still registered correctly, and KeymapImpl.addShortcut is never called with a nil shortcut.
