Unity batch mode process freezes for Android builds

    We moved to 2020.3.2f1 and are trying to fix our Intel Mac mini build machine.

    iOS builds and is playable; however, the android build just freezes ever since updating Unity.

    I can open the project in the editor and build and run on the build machine.

    Occasionally I connect to the build machine and see a system dialog ‘Unity Hub wants to make changes’. It’s not supposed to be showing dialogs in batchmode.

    Here is the command line I am using to test:

    /Applications/Unity/Hub/Editor/2020.3.2f1/ -projectPath /Users/teamviewer/builds/AbxzEpLH/0/thisco/myprojectname -executeMethod BuildCommand.BuildAndroidDevelopmentRemote -buildTarget Android -batchmode

    I can confirm that 2020.3.2f1 is the correct version of unity.

    There is no error message.

    Here is a tail of the log:

    Baking can take a spectacularly long amount of time, hours and hours even. Since the last entry is enlighten, that would be my first investigation. Bake all your lights or simply disable all baked lighting, try to build.


    How to troubleshoot build failures:

    First, make a blank project with a single blank scene and prove that it builds successfully.

    If the blank project does NOT build, go fix your Unity installation or your other tools, such as Android SDK, NDK, JDK, etc. It may even be necessary to change to a different version of Unity3D. It is generally best to stay with LTS versions of Unity3D.

    Until you can build a blank project to the target platform, don't fiddle with anything else.

    Once you can build a blank project, now bisect the problem by bringing over parts of your current project and building it one subsystem at a time, perhaps stubbing things out that might trigger compiler errors.

    Most often things that prevent building are third-party libraries such as Firebase.

    Once you identify the subsystem, go to the documentation for it and make sure you are doing it correctly.

    It may also be helpful to work through a tutorial or two for whatever subsystem is making the build fail.

    Android build not building:

    Recently (circa July 2022) there have been reports of Unity's installer failing to install the Android Tools.

    Here was how I brought up Unity2020.3.41 and the Android SDK 31 on October 30, 2022 (edited on August 23, 2023 to include Android SDK 33...):
