Builds folder is empty for some 2017 unity versions

Issue

I'm tring to build for 2017.4 Unity version with StandaloneWindows64 target, and build don't work properly. At the end /root/project/Builds folder is empty.

Detail

Using the following versions of unity, the Builds folder is empty and no artifacts is produced:

• 2017.3.1
• 2017.4.2
• 2017.4.4
• 2017.4.6

Instead build propertly works using:

• 2017.1.0

Evidences

The difference I noticed during the build among the different versions of unity is the following:

Log related to Succesful Build

- Finished compile Library/ScriptAssemblies/Assembly-CSharp.dll

It seems like StandaloneWindows64 target is not properly installed.

NOTE: I tried using your unity docker image and tried to build my own. In both cases I tested on gitlab-ci and i local. The result is always the same.

Here the full log files showing the difference highlighted above:

• Working build 2017.1.0.log
• Empty build 2017.3.1.log
• Empty build 2017.4.2.log
