Building on linux

Hi.

I am trying to get an automated build setup on linux.

I created a new project from the Third Person c++ template.

The current command I am running is this:

./Engine/Build/BatchFiles/RunUAT.sh BuildCookRun -nop4 -platform=Linux -project=$PROJECT_PATH -cook -compressed -allmaps -stage -archive -archivedirectory=$DIR/out -package -LinuxNoEditor -clientconfig=Development -serverconfig=Development -server -noclient -clean -pak -targetplatform=Linux -utf8output

(for exact commands see Build EU4 server on ubuntu. ยท GitHub )

I get the error:
Program.Main: ERROR: All branches must have the blank project /Samples/Sandbox/BlankProject

Full output here: https://gist.github.com/PhroZenOne/146f94d4a25f8ed44f7f

Has anyone a good example on how to get this working or what I am doing wrong here?

For others stumbling over the same error. In my case the problem was that I was pointing at a non existent project. Fixes the project path and I got a bit further.
