UE4 build after cancelling not showing results

Development Getting Started & Setup
#1

Hi. I’m building UE4 from source. Last day I:

  1. clicked “build”, it took 40-50 minutes doing nothing and didn’t show any results except
    “Build started” and “Building UE4Editor and ShaderCompileWorker”

  2. I cancelled the build and started rebuild, it showed results and took 10 hours, but not yet finished because

  3. I cancelled build because it was late night.

Today I’m starting build again but it doesn’t show results (during rebuild it showed)

Is there a fix for that or why is that?
