[analysis_server_plugin] Analyzer plugins not working in workspace?

[schultek]

I'm trying to setup and use a custom analyzer plugin in a Dart workspace, but there are several things that are not working.

I have a workspace-level analysis_options.yaml that defines the plugin from path, e.g.

plugins:
  jaspr_lints:
    path: packages/jaspr_lints
    diagnostics: ...

Result:

• ✅ Plugin gets detected according to analyzer diagnostics page
• ❌ No lint warnings reported in IDE
• ❌ No lint warnings reported with dart analyze
• ✅ Assists available in IDE
