Plug-in "com.genuitec.copilot4eclipse.chat" was unable to instantiate class "com.genuitec.copilot4eclipse.chat.ui.AIChatView2".

[GabrielRP777]

How can I solve this error: Plug-in "com.genuitec.copilot4eclipse.chat" was unable to instantiate class "com.genuitec.copilot4eclipse.chat.ui.AIChatView2".

[wayneparrott]

My 1st thought is your installation goofed up.
Can you try uninstalling and then reinstalling Copilot4Eclipse? Let us know the outcome.

This is the error

[GabrielRP777]

I have uninstalled it several times, also Eclipse and nothing

[wayneparrott]

Thanks for trying the reinstallation approach.

Some questions:

1. What version of Eclipse are you installing Copilot4Eclipse into?

2. Can you try using a new workspace to test if the issue is related to the workspace. The Copilot4Eclipse Chat system seems to be having trouble with it's internal db it uses for persisting the conversations in the workspace. This db is created in the /.metadata folder .

2a) Is there anything special about the filesystem where your workspace resides?

I'm looking into this more closely.
Can you share a little more info about your environment:

1. OS version
2. Java version

Also can you try this:

1. reboot your computer
2. delete the /.metadata/.plugins/com.genuitec.copilot4eclipse/chatdata/ folder
3. start eclipse
   Is the error still present?
