Installing Eclipse with bundled JRE [message #1837877]

Hi,

my goal is to provide an Eclipse installation for a team using the Eclipse installer. One thing is, that we develop in Java 8 but want to use the current Eclipse distribution which requires Java 9+.
Since the default environment of the users don't have a Java 9+ installation on their computer, I thought it might be possible to install a bundled (JustJ?) JRE (11) with the Eclipse installation and use this one to start Eclipse.
I tried adding the JustJ repository and requirement to my .setup file, but it won't set the -vm argument in the eclipse.ini to this.

Can anyone help me setting what to put into my setup file?

Also, if possible, the selection of the JRE on the product choosing wizard page could be disabled this way. Is that possible?

Thanks in advance!
Sascha

The installer already gives a choice of a JustJ JRE:

There is not yet a way to supress that choice.

But Oomph is open source so if you wanted that you could help contribute toward that fund someone to do that. Likely some special value (0?) for ProductVersion.requiredJavaVersion to indicate that no Java version is required because the product will install the required JRE would do the trick.

Thanks for your quick response.

It seems something is not working the way is should for me. Could it be because I redirect oomph to my own local org.eclipse.setup (for hosting an own index with products/projects)?

I installed the latest EclipseInstaller with JRE.

Ok, so disabling the JRE Chooser was a bit optional for me, but I will see what I can do :)

Yes, if you have an older copy, you'll need to update it.

This annotation is present

https://git.eclipse.org/c/oomph/org.eclipse.oomph.git/tree/setups/org.eclipse.setup#n14

And that causes this resource to be available :

https://git.eclipse.org/c/oomph/org.eclipse.oomph.git/tree/setups/org.eclipse.jres.setup

Via the annotation it is located and used by the wizard in org.eclipse.oomph.setup.ui.wizards.SetupWizard.IndexLoader.indexLoaded(Index)
