Improved Marketplace Installation for Headless Mode

Entry
JSON All of v2.1.21
EntryKind: in v2.1.21,
ChangesSection of the release

Plugin installation in headless/SDK mode now supports extra marketplaces and has better error reporting.

Details
  • Now installs plugins from all configured marketplaces, not just default
  • Skips plugins from unknown marketplaces with clear logging
  • Individual marketplace installation failures don't block other installations
  • Logs: installPluginsForHeadless: installed extra marketplace <name> on success
  • Logs: installPluginsForHeadless: failed to install extra marketplace <name> on failure
  • Logs: installPluginsForHeadless: skipping N plugins from unknown marketplaces: <list>
Evidence

Lines 580240-580263 (marketplace installation loop, contains "installPluginsForHeadless: installed extra marketplace" and "skipping ${J.length} plugins from unknown marketplaces")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
