[Oomph] Can we limit the JRE versions to choose in the Installer? [message #1700123]

I would like to enforce the same JVM version in the installation for all developers, regardless the versions the developer may have installed in his machine.

Is this possible with Oomph?

In Oomph's setup we specify a JRETask like this:

<?xml version="1.0" encoding="UTF-8"?>
<jdt:JRETask
xmi:version="2.0"
xmlns:xmi="http://www.omg.org/XMI"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:jdt="http://www.eclipse.org/oomph/setup/jdt/1.0"
xsi:schemaLocation="http://www.eclipse.org/oomph/setup/jdt/1.0
http://git.eclipse.org/c/oomph/org.eclipse.oomph.git/plain/setups/models/JDT.ecore"
version="J2SE-1.5"
location="${jre.location-1.5}"/>

IIRC., higher JREs are considered valid substitutes.

Cheers

So I imagine that we are not able to block an higher JRE from being selected.

Another solution would be to allow to provision a JDK/JRE from the Oomph itself. I don't know if this makes sense at all.

Correct.

Hard to say. Maybe you elaborate a little what you're imagining ;-)

I want to enforce that all developers uses exactly the same setup for a given stream development, such as the version of Eclipse IDE, the Target Platform and other preferences. With Oomph this becomes very easy to implement and maintain.
However, with the current approach I cannot do the same for the JRE. Though the JRE is suppose to be fully compatible with previous versions, our product is tested for a given JRE version and shipped with that JRE, so I would like to restrict the version during installation. This would also ease the installation because the developer wouldn't need to install the JDK previously.

I'd like to discuss this topic with Ed but he's currently on travel. Can you please open an enhancement request as a
reminder?
