1>[Upgrade]
1>[Upgrade] Using backward-compatible build settings. The latest version of UE4 sets the following values by default, which may require code changes:
1>[Upgrade] bLegacyPublicIncludePaths = false => Omits subfolders from public include paths to reduce compiler command line length. (Previously: true).
1>[Upgrade] ShadowVariableWarningLevel = WarningLevel.Error => Treats shadowed variable warnings as errors. (Previously: WarningLevel.Warning).
1>[Upgrade] PCHUsage = PCHUsageMode.UseExplicitOrSharedPCHs => Set in build.cs files to enables IWYU-style PCH model. See https://docs.unrealengine.com/en-US/Programming/BuildTools/UnrealBuildTool/IWYU/index.html. (Previously: PCHUsageMode.UseSharedPCHs).
1>[Upgrade] Suppress this message by setting 'DefaultBuildSettings = BuildSettingsVersion.V2;' in 工程名Server.Target.cs, and explicitly overriding settings that differ from the new defaults.

1>已完成生成项目“工程名.vcxproj”的操作 - 失败。
========== 生成: 成功 0 个,失败 1 个,最新 2 个,跳过 0 个 ==========
处理:
(1)模块名.h 文件添加:
public:
/* This will get called when the editor loads the module */
virtual void StartupModule() override;
/* This will get called when the editor unloads the module */
virtual void ShutdownModule() override;
(2)模块名.cpp文件
(2.1)添加:
void 模块名::StartupModule()
{
}
void 模块名::ShutdownModule()
{
}
(2.2)游戏主模块唯一性:
? //IMPLEMENT_PRIMARY_GAME_MODULE( ModuleImplClass, ModuleName, GameName )
IMPLEMENT_PRIMARY_GAME_MODULE( FDefaultGameModuleImpl, 模块名, "游戏名" );
改为
? //IMPLEMENT_GAME_MODULE( ModuleImplClass, ModuleName )
IMPLEMENT_GAME_MODULE(模块实现类名, 模块名);
