Importing projects with different Java-Version [message #1714281]

Given i have a setup task , which imports multiple projects. Each of them requires a certain java version.

My idea would be to create variables with paths to different java JDKs and then tell the project import task to set the appropriate java path for a specific project.

Now my question is, is it possible to tell the projects import task to set the java path for a specific project ?

Typically that's a minimum requirement, not a strict requirement.

How is the project import task involved? Isn't a JRE task sufficient?

Normally projects specify a BREE and based on the available JREs they
are bound to the best match.

So you want to say, that if I input several JREs as JRE tasks, then each project will be bound to the best match ?

Maksim,

Yes, that's generally JDT's behavior. It's very hard to find old JDKs
these days though, so I'm not sure specifically what your concern is.
Most people just get a JDK/JRE 1.8 and use it for everything. There
are EE profiles that can check that you aren't using features
(methods/classes) of a newer JRE that aren't present in the BREE's exact
JRE.

Hi,

I think if a project needs a specific JRE then that should be configured in the project's Properties dialog (right-click
on the project). I've attached a screenshot...

Cheers
