Hi guys,
I am using the Jenkins implementation from Skymaps (GitHub - skymapgames/jenkins-ue4: Automated Unreal Engine 4 Project Builds) with some small additions to make it work on my computer (and on 4.18) but the strangest thing happens sometime.
The build fails but a “manual build request” will succeed. Sometimes the automatic build succeeds and sometimes a workspace deletion and build will fail when the next time it won’t. All in the same project and same code.
The problem always arised on Step 3 which is the following command on my system
"C:\Program Files\Epic Games\UE_4.18\Engine\Build\BatchFiles\RunUAT.bat" BuildCookRun -project="C:\Source\demoworkflow\TestingGrounds.uproject" -noP4 -platform=Win64 -clientconfig=Development -cook -allmaps -build -stage -pak -archive -archivedirectory="C:\Builds\demoworkflow"
and always with the same errors
14:46:19 LogInit: Warning: Incompatible or missing module: UE4Editor-TestingGrounds.dll
14:46:19 Took 1.4699086s to run UE4Editor-Cmd.exe, ExitCode=1

So it just seems that the DLL is the big problem but why does it sometimes generate and sometimes don’t? The only remotely extra maybe informative line I can find is
15:09:28 LogModuleManager: Warning: Module file ../../../../../../Source/demoworkflow/Binaries/Win64/UE4Editor-TestingGrounds-4053.dll is missing. This is likely a stale module that must be recompiled.
Am I missing some argument somewhere? Why does the same build sometimes fail and sometimes don’t? I’ve even selected the drastic method to always clear the full workspace (which means that the GIT command will take >5 minutes) but not even this solves this problem.
The Step2_CompileScripts.bat has also been editted to
"C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\MSBuild\15.0\Bin\MSBuild.exe" "C:\Source\demoworkflow\TestingGrounds.sln" /t:build /p:Configuration="Development Editor";Platform=Win64;verbosity=diagnostic
