Just updated to the latest build (V8.0.0.2370) and find out that the fbcmd ignores variables with empty values:
before update:
2018-02-21T09:05:18.9163878Z ##[command]“C:\Program Files (x86)\FinalBuilder 8\FBCmd.exe” -v I don’t see in the log that Variable DocumentationFolder is set to be empty and in the script itself the default value is used.

Hi Markus
I can confirm it’s a regression, and unintended consequence of another bug fix. This build has a fix for it :
[http://downloads.finalbuilder.com/downloads/finalbuilder/800/FB800\_2398.exe](http://downloads.finalbuilder.com/downloads/finalbuilder/800/FB800_2398.exe)
We’ll have an official update out in the next few days.
