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.

We had modified our working plugin code with lamba expression and then on deployment we are facing the "We are using lamba expression in plugin code" . Can we assume that lamba expression support don't exist
