I have created a plugin in 4.6 and want to transfer the project to 4.7. The plugin was compiled without error, but I found all of the custom component classes disappeared from the “Add Component” list(they could be found in 4.6.)

Could you please tell me how to fix this?

Solved!  
I added “ClassGroup = (Custom)” to the class specifiers and rebuild the project. (Not by hot reload but close the Editor and re-open.)  
Now my custom components can be found in the “Add Component” list!
