$ mach bootstrap

Actual results:

mach bootstrap is not fully implemented in MozillaBuild

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: 4
   Error running mach:

['bootstrap']

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 can invoke |./mach busted| to check if this issue is already on file. If it
isn't, please use |./mach busted file bootstrap| to report it. If |./mach busted| is
misbehaving, you can also inspect the dependencies of bug 1543241.

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

The details of the failure are as follows:

FileNotFoundError: [WinError 2] The system cannot find the file specified

File "c:\mozilla-source\moz-central\mozilla-central\python/mozboot/mozboot/mach_commands.py", line 44, in bootstrap
bootstrapper.bootstrap()
File "c:\mozilla-source\moz-central\mozilla-central\python/mozboot\mozboot\bootstrap.py", line 478, in bootstrap
getattr(self.instance, 'install_%s_packages' % application)()
File "c:\mozilla-source\moz-central\mozilla-central\python/mozboot\mozboot\mozillabuild.py", line 70, in install_mobile_android_packages
self.ensure_mobile_android_packages()
File "c:\mozilla-source\moz-central\mozilla-central\python/mozboot\mozboot\mozillabuild.py", line 83, in ensure_mobile_android_packages
r'SOFTWARE\JavaSoft\Java Development Kit\1.8')

Expected results:

mach bootstrap should have completed successfully for GeckoView/Firefox for Android.
Note: failed for both 3 and 4 options (artifact and non artifact build for GeckoView/Firefox for Android)

(This looks related to this Sentry issue).
This error is a little cryptic, but you need to install the Java 1.8 Development Kit (JDK 1.8).
You can download it from here.

However, this error message and the documentation can be improved, so I'll leave this ticket open.
(let me know if installed JDK 1.8 doesn't solve this issue for you)
