Paste for posterity:

➜  mozilla-central ./mach bootsrap  
We're assuming the 'bootsrap' command is 'bootstrap' and we're executing it for you.


Note on Artifact Mode:

Artifact builds download prebuilt C++ components rather than building
them locally. Artifact builds are faster!

Artifact builds are recommended for people working on Firefox or
Firefox for Android frontends, or the GeckoView Java API. They are unsuitable
for those working on C++ code. For more information see:
https://developer.mozilla.org/en-US/docs/Artifact_builds.

Please choose the version of Firefox you want to build:
1. Firefox for Desktop Artifact Mode
2. Firefox for Desktop
3. GeckoView/Firefox for Android Artifact Mode
4. GeckoView/Firefox for Android
Your choice: 3

Looks like you have Homebrew installed. We will install all required packages via Homebrew.

Error running mach:

    ['bootsrap']

The error occurred in code that was called by the mach command. This is either
a bug in the called code itself or in the way that mach is calling it.

You should consider filing a bug for this issue.

If filing a bug, please include the full output of mach, including this error
message.

The details of the failure are as follows:

Exception: You need to have Java version 1.8 installed (found /usr/bin/java with version "11"). Check the JAVA_HOME environment variable. Please visit http://www.java.com/en/download to get version 1.8.

nalexander, do you know why we require a specific Java version and where one can obtain said version?

This is a hard requirement from the Android SDK tools. I broke it down in this comment: https://bugzilla.mozilla.org/show_bug.cgi?id=1477487#c11. I think this ticket is a dupe of Bug 1445729.

This is related to Bug 1519180, but not the same.

Just FYI, we try pretty hard to install java8 exactly using Homebrew -- see https://searchfox.org/mozilla-central/source/python/mozboot/mozboot/osx.py#368 -- so I'm surprised we're finding the wrong one.
