Resolving editor module dependencies, how?

I’m planning on extending the editor with a module. I have followed the setup mentioned in here: https://answers.unrealengine.com/questions/41509/extending-editor-engine.html . I also followed the instructions in wiki: A new, community-hosted Unreal Engine Wiki - Announcements - Unreal Engine Forums . I have 2 modules, one for game and another for editor which contains the editor specific extensions.

Now the problem is that I’m unable to find a way to satisfy the dependencies for the editor module. Is there any instructions or documentation how can I dig up the appropriate modules to include?

The extended editor class I have is defined like below.

#include "AnimGraphNode_BlendSpacePlayer.h"
#include "Animation/AnimNode_DynamicBlendSpacePlayer.h" // My custom class
#include "AnimGraphNode_DynamicBlendSpacePlayer.generated.h"

UCLASS(MinimalAPI, dependson = AnimNode_DynamicBlendSpacePlayer)
class UAnimGraphNode_DynamicBlendSpacePlayer : public UAnimGraphNode_BlendSpacePlayer
{
    GENERATED_UCLASS_BODY()

I know that the UAnimGraphNode_BlendSpacePlayer class is defined in AnimGraph module. However when I add it I get following error.

1>LogCompile : error : Duplicate class name: UK2Node_BaseAsyncTask also exists in file /Script/OnlineBlueprintSupport
1>C:/apps/Unreal Engine/4.6/Engine/Source/Editor/OnlineBlueprintSupport/Classes/K2Node_InAppPurchase.h(7): error : Superclass K2Node_BaseAsyncTask of class K2Node_InAppPurchase not found
 ... etc

I can get around this problem by adding AnimGraph into circular references, but then I get following error.

1>E:/programming/projects/Unreal/FastOps/Source/FastOpsEditorExtensions/Classes/AnimGraph/AnimGraphNode_DynamicBlendSpacePlayer.h(7): error : Superclass AnimGraphNode_BlendSpacePlayer of class AnimGraphNode_DynamicBlendSpacePlayer not found
1>Error : Failed to generate code for FastOpsEditor - error code: OtherCompilationError (2)
1>  UnrealHeaderTool failed for target 'FastOpsEditor' (platform: Win64, module info: E:\programming\projects\Unreal\FastOps\Intermediate\Build\Win64\FastOpsEditor\Development\UnrealHeaderTool.manifest).

I couldn’t find any mention of the parent class in the manifest. I have looked at AnimGraph’s module dependencies but even adding those all to my own project I have not been able to make this compile. The latest setup I have build configuration is as follows. How can I find the appropriate modules to be added into my build config? Hopefully this is not something “you need to know”.

PublicDependencyModuleNames.AddRange(new string[] { "FastOps", "Core", "CoreUObject", "Engine" });
PrivateDependencyModuleNames.AddRange(new string[] { "AnimGraph" });
CircularlyReferencedDependentModules.AddRange(new string[] { "AnimGraph" });

EDIT
Attached example source to reproduce the problem. Add these modules into your UE project and add following modules into the project file:

	"Modules": [
		{
			"Name": "FastOps",
			"Type": "Runtime",
			"LoadingPhase": "Default"
		},
		{
			"Name": "FastOpsEditorExtensions",
			"Type": "Editor",
			"LoadingPhase": "Default"
		}
	],

Any help on resolving the dependencies? I’m pretty much stuck with this and don’t know where to look further…

Managed to dig out the correct dependencies (“UnrealEd”, “BlueprintGraph”, “AnimGraph”) for animgraph.

Helped me a lot, thank you!
