Hi Albert,
Forgot mention: the is also "$HOME/.eclipse".

I agree the developer documentation is not that easy to find yet. Once the developer documentation is deployed, we can ensure NOTICE, CONTRIBUTE and project pages all point there.

I agree the 'org.eclipse.escet.documentation' project doesn't really fit in the 'products' directory. It is there now, as it is the documentation for the entire project/product, and it includes the developer documentation. I'm not immediately sure in which other folder to put it. Do you have any suggestions?

Putting the setup file on your local disk should work. The only thing is that it will then not redirect to the location in the Git checkout
later on, so it will still be linked to the local disk location, and won't change when you e.g. switch branches. You can always manually edit eclipse.ini of your development environment to add a redirect for your own custom local disk location. Or you can use
the online URL as in the instructions.

If
you have a specific error message, I may be able to help with this. I've seen quite a few different errors over the years. For me the recent setups have been very stable.
One
thing I can remember is that it was once trying to use IPv6 and failed. Setting the following environment variables helps to prefer/enforce IPv4 and solve many download issues:
_JAVA_OPTIONS=-Djava.net.preferIPv4Stack=true
_JPI_VM_OPTIONS=-Djava.net.preferIPv4Stack=true
(yes,
the environment variable names really start with an underscore)

There
is indeed some information at "$HOME/.p2".
If you disable the P2 pool in the Eclipse
Installer (Oomph) it will install all the features/bundles to the installation directory you choose. Your existing P2 pool will then not be used and new new features/bundles will not be put in your global p2 pool. You can also have multiple P2 pools and P2
agents.
Some background information that may be useful here:
It does indeed also remember the Oomph setups that you've added in the past. You may remove them on the Eclipse Installer (Oomph) 'page' where you can also add a new setup. It sometimes helps to first remove the old ones and then add a new one, especially if
they have the same name/id.
> [...] which

All your installations have a profile that is indeed stored in the "$HOME/.p2" directory somewhere (unless you changed the P2 location yourself). This way P2 (and
thus Oomph) know what installations you have, and what bundles in the P2 pool are used by what installation. It also allows it to clean up no longer needed bundles, for installations that you've removed. You can do that for instance with the Eclipse Installer
(Oomph).
None of this should effect other Eclipse environments you set up using Oomph. It surely won't affect any Eclipse environments you obtained by simply extracting
a ZIP with an Eclpise IDE-based product.

I've
not seen or heard about this problem, when following the instructions in the developer documentation. That is, except for the earlier things I mentioned relating to removing/readding the setup in case of name/id overlap and obtaining the Oomph setup from different
locations.
> [...] unpacked the installer again [...]
Did you just download the Eclipse Installer, or is an old version
that you downloaded a longer time ago?
I hope this information helps you resolve your issues. If not,
please let me know.

Hello,
I thought it would be useful to get a fresh instance of Eclipse etc after adding a ssh key, so I looked for the docs for install.
NOTICE.asciidoc is useless, and CONTRIBUTE.asciidoc is useless as well.
The latter got closest by point at
https://projects.eclipse.org/projects/technology.escet/developer for "source code management, builds, setting up a developer environment, coding standards, how to contribute, and more", but that link doesn't fulfil its promise at all.
I knew we have dev docs, which I eventually found in "products/org.eclipse.escet.documentation/asciidoc". No idea why it's there, I wouldn't even think of looking in "products" for development docs.
Following the docs (except with the current setup file at the file-system), I set it up in a new directory, with the only connections to existing files being the java 8 SDK, and the .p2 repo.
I got as far as downloading stuff by oomph, but failing at downloading some of the files at dl-tray.com. A while later that still failed, so perhaps there was something wrong with the setup.
I deleted the unpacked installer as wel as the "installed" sub-directory set as target for the installed version, unpacked the installer again, and restarted the process.
It knows previously made selections, so the install is getting information from elsewhere, which also means it's making a mess in my other Eclipse installs.
Also, it now claims that the .setup file is invalid ("does not contain a valid product") even though I used the same file an hour before when it failed at the download, and downloading the file manually again and comparing gives no difference.
So I am fully stuck with this GUI giving me no information at all how it reaches its incorrect conclusion, and very unhappy that it spreads settings to outside the directory I set as install destination.
