How can I use game specified data with plugin?

Hello. I’m newbie in UE 4.

I’m implementing some plugin using engine data and game specified data(for example, geometry or event or separation of game space).
The extracted data should be in form of class. And both plugin and game module can use that data.

I include game module’s public dependencies in my Plugin.Build.cs. But it doesn’t work.
NO problem with compile & build. But If I run my project, then occurs error.
Error message is like this → “can’t find ~~~/UE4Editor-core.dll or it is crashed image.”.
I tried rebuild my project several times. But there is no change.
