Failed to Generate Project Files 4.8 preview

Hi Epic,

I have the MMO Starter Kit that was built by one of the UE community member. And I thought I would create a new file and Switch it to 4.8 binary and I get this error. I got the same error last weekend with the github build from source. I know it is a preview but I am sending you my error so you can fix it. I have built this with 4.7 with no problems.

here is my error

Hey -

Since the starter kit was created by a community member your best bet would be to contact that member for updated information (MMO Starter Kit - World Creation - Epic Developer Community Forums). It is the creator’s responsibility to offer support for the custom content they create.

Cheers

I’m having the same issue

error CS0117: 'UnrealBuildTool.UnrealBuildTool' does not contain a definition for 'BuildingRocket' UnrealBuildTool Exception: ERROR: UnrealBuildTool encountered an error while compiling source files

but i’m not using any external package, just my project that i was always able to convert. I’m using 4.8 from github.

Change BuildingRocket() portion of your GameServer.Target.cs (or CleanThirdPersonServer.Target.cs if you’re using the MMO kit) to IsEngineInstalled().

I took it from piinecone’s answer to this question.
