Build Failed Unknown error Automation tool terminate

ok so I’ve really been struggling with this one for a while. The first time I tried to build my game out a few weeks ago I recieved this build failed unkown error. I’m using the SteamVr template by proteus but it fails with other templates and projects too. I can get the default projects to build, but none of the others. I poured over these forums and tried many different things to get it to work.

I tried reinstalling ue4, visual studio and also making sure updating vs 2015 to include the c++ tools. nothing worked until on a whim i created a new project and imported all the levels i was using into that project. So it did builds fine for a few weeks until yesterday. I had changed the level blueprint to the first level of my game to include the console command “stereo on” and added an icon, thumbnail, and splash screens to the game.

Then it started to fail in the building again. I undid all my changes but it still would fail in the building. i created a new project, added the blank c++ class it needed and it still failed. Then I tried another project, same result. I’ve been pouring over these forums for days and nothing seems to fix it. The original fix of just migrating the levels to a new project no loner works, just produces the same error.

Anyway if anyone can help it would be a lifesaver. Here is the output log from the build, I tried to find the logfile referenced in the output next to the error but couldn’t find it.link text:

thanks in advance, it’s driving me nuts i want to continue designing but can’t until i’m sure i can package a final build.

Hey illpoet,

I see that the error in your logs refers to an external plugin: UnrealBuildTool: C:/Program Files (x86)/Epic Games/4.12/Engine/Plugins/Marketplace/PathFollow/Source/PathFollow/Classes/PFPathBase.h(20) : Property is exposed to the editor or blueprints but has no Category specified.

Have you attempted to build a project that was not using that plugin? I recommend removing it from the project and attempting to package the game again.

Let me know if the issue is still occurring after removing the plugin.

Have a great day

That fixed it thank you times one thousand! i would have never figured that out, i thought it was a weird visual studio problem. I’ll make the dev of the plugin aware of the issue, possibly its conflicting with the steamvr template or steamvr plugin…
anyway, I can’t figure out how to mark this question as “answered” i really appreciate your help, and plan on adding you to the credits of the game under special thanks!

Hi,

yes, the bug comes from the PathFollow plugin.
Already fixed. The fix will be included in next update of the plugin.
Sorry for your troubles,

Jiri (PathFollow creator)
