Ed,
I'm extremely pleased to be able to report that following your
suggestions, I've got a working jdt-master eclipse build! Mucho grass!!
My next challenge is persuading some veteran jdt committer to serve as a
code-buddy as I dive into hacking ejc. While I'm a noob re: eclipse
development, I'm pretty seasoned in most development practices, and a
veteran of many system, language, and tool wars over many years. I can
promise I won't be too much of a pest, and if pointed to docs, will do
my best to absorb them in detail before asking for help.
What would be fantastic would be links to How Tos covering
* how to run unit and regression tests on ejc
* best practices for deploying mods to stock eclipse installs, and
rolling them back
Thanks to y'all who've helped get me get up to this ledge on Mt. Eclipse.
Cheers,

Richard,
It sounds like you selected the SSH URIs for cloning. I.e., not
https://git.eclipse.org/r/jdt/eclipse.jdt but rather
ssh://${git.user.id|username}@git.eclipse.org:29418/jdt/eclipse.jdt
correct?
I assume you have an Eclipse account, but have you uploaded your
public key to the server as described in the Gerrit wiki that's
referenced by the documentation? I.e., specifically from this section:
https://wiki.eclipse.org/Gerrit#Git_over_SSH
Also, has an entry for "[git.eclipse.org]:29418 ssh-rsa " been added
to your ~/.ssh/known_hosts?
Note that it would be better to use
https://bugs.eclipse.org/bugs/show_bug.cgi?id=536533 as documented in
the wiki as the place to ask questions or to provide suggestions for
improvements. This way the next person who has such an issue will be
more likely find the answers.
Regards,
Ed

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):

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://[email protected]:29418/jdt/eclipse.jdt.core.git*) with
the magic *29418
<ssh://[email protected]: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,
