Unable to scan for host components in plugin classes

Can you share a full stacktrace? I'm wondering if there is something in there that may make this more clear. I've personally never seen this error and have done a lot of plug-in development.

Does this apply to only a specific plugin or all plugins? If the former, was the plug-in changed at all, such as with a new version? If so, are you able to successfully deploy the old version? Can you try deploying another plug-in just to make sure the plug-in framework itself is functioning correctly and that this error is isolated to a single JAR

This error seems to be more related to the OSGI framework so I would double check the contents and structure of the JAR match the documentation (docs.appian.com/.../Appian_Plug-ins.html), and the appian-plugin.xml has the correct values.
