    Key error message portion:
    [Unity] Failed to install the following SDK components:
    [Unity] [Android SDK Build-Tools 27.0.3]
    [Unity] The SDK directory (/UNITY_PATH/Unity/android/sdk_latest) is not writeable,

    I'm not sure what version of build tools
     /UNITY_PATH/Unity/android/sdk_latest
    actually contains, if its a 27.0.x, then I'm happy to change my build.gradle versions to temporarily work around this issue.

    That install of the android SDK is currently using version 27.0.1 of the build tools.

    Thanks so much! Is there anything else I can do to work around this aside from editing a bunch of build.gradle files?

    Or do you think a fix on your end is coming in a day or two and I should just wait?

    Upgrading the installed version of the build tools there isn't planned in the short term.

    Understood! The error message made me wonder if it was intentionally read-only to disallow upgrading of build-tools at build time, and I guess it is.

    Is there a document/url you could point me to that I can use, long-term, to ensure my 
    gradle.build
    files are compatible with Cloud Build?

    There's a lot of issues like these that crop up in the forums, (e.g. such and such not supported yet, etc.) so a compatibility matrix would be nice, even if some of the entries where "unknown". I'd much rather self-troubleshoot than bug you on the forums.

    Will updating to 2017.4.17f1 cause problems with Cloud Build, in that case?

    2017.4.17f1 Release Notes
    Features
    - Android: Added App Bundle generation support.​
    Backwards Compatibility Breaking Changes
    - Android: Android Gradle plugin is updated up to version 3.2
    - Android: Required Android build tools version is increased up to 28.0.3​

    Sorry, I missed your other post earlier this week. We don't have a doc outlining compatibility of android sdk versions / Unity versions in UCB.

    As for 2017.4.17f1, it will build with 28.0.3 as indicated (when it gets added shortly). If your gradle files specify a different version then yes that is likely to break until they are upgraded.
