Rush build error

It’s my first time building an extension .
So I took an open source extension and modified some things in it but when I tried to build with rush I got sone errors like this one :

erro src\com\jdl\NotificationStyle\NotificationStyle.java:12: cannot find symbol
│      import com.google.appinventor.components.annotations.DesignerComponent;
│                                                          ^
│        symbol:   class DesignerComponent
│        location: package com.google.appinventor.components.annotations

I think it needs some libs but I don’t know how to download or use them

Rush doesn’t support the @DesignerComponent annotation. Check out this open-source project or you may try the new tool FAST-CLI.
