| Re: [platform-dev] Need some more current pointers for getting started on JDT projects |
_______________________________________________Hi Ed,
Taking your advice, I've been trying to follow (https://wiki.eclipse.org/Eclipse_Platform_SDK_Provisioning), and it went pretty much along the Tutorial's path, until the provisioned IDE was launched, at which point, the Task List view shows
and clicking Details popped-open the attached Error Log.
At this point, I have no idea in what state the SDK's internal invariants are, hence what my next step should be, obvious choices being
- Is the IDE hosed and I need to start over?
- can this be ignored and all will be well going forward?
- is there a voodoo ritual that will unwedge and allow proceeding?
Kudos to you for whatever role you played in implementing the installer! Great tool!
Much 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,
