Hi, I'm currently trying to set up a configuration file for a Travis OSX Build Job which builds for multiple platforms and found a myriad of tutorials and travis.yml files for older unity versions. However, I did not find any download links or similar for 2018 other than the Unity Download Assistant. I found this page: https://docs.unity3d.com/Manual/InstallingUnity.html which describes how to install Unity from the command line using e.g. Unity.pkg, but it does not describe where/how to download that package (or any other) via command line. How do I get unity to be downloaded and installed on a CI Build Slave through the command line? If it matters, I'm on the personal subscription plan.
