Hello,

However, this is not enough when we go to a different Eclipse version or a different Java version. In such cases
we must unfortunately create a new development environment from scratch. Luckily we won't have to do this that often.
What exactly does this mean?
Only install a new Eclipse program, or also run the setup file?
In the latter case, can I re-use the existing git repository and installed location?

Hi Albert,
I planned to send a mail to this list after merging the branch for Eclipse 2021-03 and Java 11 to develop, but I forgot. Sorry about that.
For a lot of changes we make to our Oomph setup, like different dependencies, different settings, etc, we can just rerun the Oomph tasks within our existing development environments. That is, with an up-to-date 'develop'
branch, simply click 'Help' -> 'Perform Setup Tasks...', make sure all tasks are selected and execute them. It may be needed to restart and then the remaining tasks will execute.
However, this is not enough when we go to a different Eclipse version or a different Java version. In such cases we must unfortunately create a new development environment
from scratch. Luckily we won't have to do this that often.
As the new development environment setup instructions indicate, there should be no need to add a Java 11 JDK to the Eclipse Installer. It should be listed already, as it
is provided by JustJ. Simply select it from the list, as given in the instructions.
It appears that for you it is not listed in the Eclipse Installer yet. It may be that you have an older version of the Eclipse Installer that doesn't include it. In that
case you can either:
I myself downloaded a new Oomph installer at some point. Updating the existing one should also work, but I haven't test that myself.
I hope this helps.
PS: Note that we have some issues with dl.bintray.com being offline, see issue #57 (https://gitlab.eclipse.org/eclipse/escet/escet/-/issues/57).
I removed some things from the Oomph setup (which thus won't be available in the development environment for now) and tried a fresh installation. It was successful.

I updated the repository and it uses a new compiler now, so I tried to update it, and it fails.
 and if you try to start a sub-eclipse:
 (list is much longer, just opened 2)
To create a development environment for a non-first time:
* In the first wizard window:
** Select _Eclipse Platform_ from the big list at the top.
** Select _2021-03_ for _Product Version_.
** For _Java 11+ VM_ select
_JRE 11.0.2 - \http://download.eclipse.org/justj/jres/11/updates/release/11.0.2_.
** Choose whether you want a P2 bundle pool (recommended).
** Click btn:[Next].
* In the second wizard window:
** Use the green '+' icon at the top right to add the Oomph setup.Installed through the eclipse software window into p2, but cannot find how to add it to the installed JREs. It insists on pointing at the file system for some reason, and pointing at the p2 file is refused as "not a compiler".
Downloading the JustJ version manually, and using that, doesn't fix the problem either.
List of installed JREs, clearly marked the justj as default.
 JustJ site at eclipse describes in great detail how you can build a p2 file, and how wonderful automatic it is. Not a single word what to do with the file, or how to tell Eclipse the file exists and should be used.
So I am stuck. Do I need to install the entire thing again from scratch?
Why does nothing ever just works in Eclipse 🙁
