Ed,
After tying-off previous engagements, I'm back trying to setup
the SDK.
The Good News: your doc (below) was extremely helpful, and after
following it to a T, I was able made significant progress,
launching the provisioning and installation process.
The Not So Good News: provisioning failed, with the following
(partial) trace (after one attempt to restart):

authentication methods available

Took 1 seconds.
There are failed tasks.
Press Back to choose different settings or Cancel to
abort.
This occurred after hitting Back, and having no hint what
settings are required, just tried clicking Finish, which failed
immediately with the above trace. Just before the failure, I got
a popup stating that, IIRC, SSH needed missing info needed to auth
the host, and gave the option to just accept all subsequent creds.
The "No more authentication methods available" error
message seems to suggest that I failed to obtain or supply some
essential keys, but am hoping that you (or one of y'all) can
pinpoint the root cause and advise how to resume the provisioning.
Thanks!

Richard,
As Paul suggests, if you really want to clone the repos and work
with (or see all) the source, better to use the installer. There
is a tutorial describing how the create an installation with the
complete platform SDK:
https://wiki.eclipse.org/Eclipse_Platform_SDK_Provisioning
Likely this is overkill for your purpose, but I find this an
extremely useful resource to have around. It can help you find
out how other things are already implemented in the platform and
provides search capabilities not possible in any other way. For
example, if I see a string some where in some dialog or elsewhere
in the UI, I can search all the source to find where that is
specified, e.g., often in a properties file. Then I can figure
out the name of that property and can search for all uses of that
property name in the *.java file files. Typically this will be
some static final constant, and then I can open a call hierarchy
on that constant to find all the places that its used. The
advantage of having all the source is that a constant's value (if
it's really a static constant with a constant _expression_), gets
inlined by the compiler, so you cannot find uses of the static
constants in other .class files. But with the source available,
you can find the uses of constants in other *.java files in the
workspace as well.
So probably best not to include all the projects from the tutorial
because that takes very long to set up, but following the tutorial
you can go back to the previous page of the installer and select
the subset of projects likely to be useful, e.g., the JDT projects
and the various platform UI projects.
Best of luck with your explorations.
Cheers,
Ed

You don't need to clone/import Platform
projects to work on JDT. If compilation failed you might not
have a correct target platform because the target platform is
what is used to resolve dependencies.
Also even if most Platform or JDT projects contain pom.xml files
you should import them as existing Eclipse projects.
I would recommend you to try Oomph setup (Eclipse Installer).
https://www.eclipse.org/downloads/packages/
* In Eclipse Installer select advanced mode
* select Eclipse IDE for Eclipse Committers (Latest)
* on the next page you can select JDT projects and any other
projects you are interested
Notes on some of your other points:
* If you get a timeout while cloning you can try it again.
Those errors are usually temporarily.
* The URLs on the Git Workflow page look outdated. In general
Eclipse git repos are listed at https://git.eclipse.org/c/ and
you can find clone URLs if you select a repo.
* Regards the using http: as anonymous. You can clone from
https: as anonymous. Anonymous only means you do not provide
your username. (as required for ssh clone)
Best regards
Paul
PS: found a wiki page for Eclipse SDK Oomph setup.
https://wiki.eclipse.org/Eclipse_Platform_SDK_Provisioning
Maybe that helps too.

[FYI, despite having reported and done a
bit of investigation on
https://bugs.eclipse.org/bugs/show_bug.cgi?id=518095, I'm
still a total eclipse noob, so please go easy on anything
stupid below.]
I have a few JDT experiments ("hacks") I want to try-out, and
have been trying to follow the instructions in the various dev
resources and guides, such as
* eclipse.org/jdt/core/dev.php
* wiki.eclipse.org/JDT_Core_Committer_FAQ
* https://wiki.eclipse.org/JDT_Core_Programmer_Guide
* eclipse.org/forums/index.php/f/13/
* and numerous others.
The central problem (that's blocking me) is the fact that none
of the above appear to be both current and correct, compounded
by the fact that none of the docs have overt last-modified
dates, nor major release level ranges. I therefore invested a
fair amount of time trying to build a JDT dev project going
down multiple routes, only to discover that each was
effectively an abandoned gopher-hole. In more detail:
* I tried to clone the repos listed in
https://github.com/eclipse/eclipse.jdt.core; determined
that maven
can build all modules from the command-line with the
-Pbuild-individual-bundles profile, but have yet to
successfully
import the modules into eclipse as a set of maven
projects, since
the project can't be compiled without the core eclipse
infrastructure jars; attempting to extract them from the
parent pom
is a total crap-shoot, given its inherent complexity (else
I might
be on my way to at least prototyping the hacks, but miles
from
creating even a personal release);
* I also tried cloning the repose listed in
https://wiki.eclipse.org/Platform-releng/Git_Workflows
(using http:
as anonymous as instructed); the first 3 clones worked,
but the next
several crapped-out with timeouts, premature EOFs, or
other faults;
url #6
(*ssh://userid@xxxxxxxxxxxxxxx:29418/jdt/eclipse.jdt.core.git*) with
the magic *29418
<ssh://userid@xxxxxxxxxxxxxxx:29418/jdt/eclipse.jdt.core.git>*
segment alludes to this link being release-specific
(viewing History
doesn't pin-point what release the page presents, but the
latest
entry is back to '16
* I was initially excited to find
eclipse.platform.common-I20190808-1800, then tracked it to
https://projects.eclipse.org/projects/eclipse.platform,
only to find
it's either not indexed there, or might be stale.
Any advice or live/good links to Getting Started docs would be
most appreciated.
Thanks,
