Android

Having problems with an error, it says,

"Overload resolution ambiguity:
public val Activity.loginbutton: Button! defined in kotlinx.android.synthetic.main,activity_main

public val Activity.loginbutton: Button! defined in kotlinx.android.synthetic.main,build_main

public val Activity.loginbutton: Button! defined in kotlinx.android.synthetic.main,login_main"

What can be done to fix this? I have until tomorrow night to get this resolved.
