Setup model for the Buildship project [message #1691699]

Hello! Our team at Gradle Inc. works on the Buildship project which will be a new Gradle integration for Eclipse. Recently we've discovered Oomph and thought it would be a great idea to set up a model for our project too. I'd like to share a few thoughts about my experience and the issues I'm facing.

First of all, the concept of Oomph is excellent. The ability to share a whole installation and workspace setup per project is really powerful and unique. Thanks you for making Eclipse even more awesome!

My concern is that it's far from being easy to build a model. The wiki page emphasizes using a model and not authoring one. The best way of figuring out how to build a setup model is to copy an existing one which is already big and try to change it. But even then one has to go though the whole installation process just to see that things were changed as expected. It would be nice to have an execution plan available even in a textual form describing the precise list of modification the installer will perform.

We code Buildship to work with all major releases from Mars back until Helios with a single code base. The way how we do it is to run our build against all these target platforms on a CI server. In case of a problem we can inspect the problem from the IDE by using a target definition file describing the particular platform. So at the end we have 6 .target files bundled to our project. This is really convenient but I haven't found the way to do the same with Oomph. Did I miss something related to targlets?

Cheers,

Donát Csikós

Thank you. It's a pleasure ;-)

You can also use the "Setup Project Model" in the New Wizard category "Oomph". It'll ask you a couple questions and
generate a setup skeleton for you, which you can then refine and test.

This list of modification not only depends on the setup model but also on the exact current state of your machine. For
example, is the Git clone already in place, what does it contain, etc..

When your bundle pool is sufficiently seeded and the Git clone(s) is in place, you can easily delete the entire eclipse
and workspace folders (only keep the clone) and run the installation again. That should take only seconds.

Please also note that the Outline view of the Setup editor is more like a preview, i.e., it shows the model with all
variables resolved and expanded. It also shows unresolved variables and gives usage/xref information for declared variables.

With targlets you can achieve the same effect by maintaining multiple Repository Lists (one per release train) and
simply switch the active one on the Variables page of the advanced installer/updater.

Checking the "Offline" box on the Confirmation page speeds up the installation/update further if you're not interested
in newer p2 repo content!

Hi Eike,

Thanks you for the quick response and the tips, we really appreciate it! I'll try creating multiple Repository lists to see how can I switch between the targlets.
Cheers,

Donát

You wouldn't switch between the targlets, but between the repo lists within the targlets. Maybe you meant that ;-)

Cheers

Thanks for the clarification, that's what I meant. Wink

In fact based on your input I was able to create a first version of the setup model and its works like charm. If you have any comments on it please let me know as later we'd like to send a request to include this model in the product catalog.
Cheers,

Donat

Hi Donat,

I looked at your setup model and I have a couple comments. I think it would be best that you submit a bugzilla to ask
for the inclusion into the GitHub.com catalog and then we can discuss the issues there.

Cheers

Donat,

I've been looking at it as well and have been making a few suggested
changes locally, but then I got side tracked by other issues. Of
course it's wasn't clear from your post that this is an Eclipse project
hosted at Github, i.e., I noticed this URL works as well:

https://raw.githubusercontent.com/eclipse/buildship/master/buildship.setup

I assume it's this one that you'd want to include in the Eclipse project
catalog, right? We can attach the suggested changes to the bugzilla you
open...
