Android build waiting on shaders takes hours on 2019.3.2f1, 2019.3.0f3, 2019.2.7f2, 2018.3.12f1, 2018.3.0f2.
I have to revert back to pre-2018.3
Please fix. This is not fixed as of 2-27-2020

OSX 2019.2.4 still takes a lot to build variants every time. Looks like the cache isn't being properly made.
I'm running the project from within a portable SSD. -

As mentioned above.
"Disabling "Optimize Mesh Data" in player settings speeds things up a little bit."
That was my issue. Thanks man, forgot I set that on.

Unity 2018.4.1f1 that came out today does not mention this issue in release notes. Is the fix for this going to be merged into 2018.4 LTS?

- PlayerLoop.SetPlayerLoop() function is ignored when playing game in Player
Resolution Note (fix version 2019.3):
"Optimize Mesh Data" in Player Settings causes build process to resolve unused vertex channels by checking all used shader variants. This used to happen in a very inefficient way, fetching the same shaders over and over again. The issue is fixed by implementing better shader data caching during the build process.
