The solution

First check whether the Build. gradle of the Android module in node_module exists. If it does, you can only regenerate it.

  1. Delete the @Capacitor dependency library in node_module.
  2. Using the commandnpm install @capacitor/core @capacitor/cliGenerate the @capacitor directory
  3. Close the project in Android Studio and return to the Welcome screen. Remove the Project from the list on the left, then click Open an Existing Project on the right to reopen the Project and compile again to recognize build.gralde as normal.
