Hi folks, I’m trying to build to package my game project. But the output log always shows an exception below:

There’s something worth to be noted:

  • I migrated this project from 4.26 to 5.0
  • There’re also some warnings and errors above the exception which are:
    1. ...\ShooterGame\Private\UI\Menu\Widgets\SShooterMenuWidget.cpp(33): error C2065: 'Visibility': undeclared identifier
    2. ...\ShooterGame\Private\UI\Widgets\SShooterDemoHUD.cpp(80): error C2065: 'ColorAndOpacity': undeclared identifier
    3. ...\Engine\Plugins\...\Camera\CameraShake.h(7): warning: UCameraShake has been renamed to UMatineeCameraShake, change to #include "MatineeCameraShake.h" and rename references
. . .

 . . .

I’m so confused right now cuz I can’t tell if it’s a C2065 problem or an UnrealBuildTool one.

It turns out I should replace these identifiers related to C2065 errors with getter and setter functions and the problems will be solved.
