Generate .setup from an existing project [message #1783377]

Hi!

We have an existing project, everything is set up. Now we want to use oomph for installation and provisioning.
We want to create a product .setup (for the eclipse installation) and also a project .setup for all the settings in the workspace, including project import, git connection and so on.

Can we generate the 2 .setups from the existing eclipse installation and project workspace?

Why we're asking: over the time, we've added some eclipse plugins. When new developers join the team, they just copy the workspace folder from someone and have the same plugins. Now, with oomph, if we are to create the .setup from scratch, we would have to evaluate which plugins are already installed (in the old workspace) and select them for installing (in the new Product Model .setup).

I can imagine that other teams have also configured oomph for old projects, how was this done? The same question for the imported projects - eclipse should be able to generate a .setup which imports all projects from the right location.

What we tried: eclipse -> Navigate -> Open Setup -> Self Products / Installation / Workspace. This gives us a .setup model. Our expectation was than these .setup files would have the same structure as the .setup files generated when clicking on Project -> New -> Other -> Oomph -> Setup Product Model (setup:Product) / Setup Project Model (setup:Project). What we get is, however, setup:ProductCatalog / setup:Installation / setup:Workspace. In other words, we don't quite get the Oomph Scopes. We only have one workspace with multiple installed plugins and multiple imported projects in it, should be a simple scenario - our expectation was that we don't need setup:Workspace or Project streams...

Can someone help, has someone done such "quick" generation of .setup models?

No, there isn't a wizard that will create complete product and project setups. Many tasks could be either part of a product setup or as part of a project setup. E.g., project setups often have p2 tasks to install tools specific to the project in addition to the base tools that are the same for all projects and hence defined in the product. There's no way to know looking at what's currently installed (which you can do with the Repository Explorer's combo which always include a choice for the installation's current profile) whether those things should be defined in the product or the project. In any case, you can very easily use the Repository Explorer to "capture" in a p2 task the requirements for what is currently installed. It's also trivial to create a Git clone task for each clone you need. And with targlets with wildcard requirements, it's very easy to import all projects in a Git clone; in fact, the project wizard will create these two things if you create a project setup in a workspace project in a Git clone. Note that most teams do not define specialized product setups; they typically just reuse one of the existing Eclipse products and define additional p2 tasks in their project setups to install additional tools in the base product.

Thanks, that helps understanding the whole concept in the beginning.

I think this will be the best approach for us too - 1. download and run the eclipse installer; 2. choose some base product, like Eclipse For Java Devs; 3. add our project.setup file in the projects page and use it. Done!

It is indeed a bit of work to declare all updates sites and p2 IUs from the old workspace that we need into the project.setup model, but after a few iterations we are ready to go on with the work ;)

Yes, it's really not so complex. Note that the use of Configurations can make all this even easier by also automating which product version to use as well as automating the selection and addition of the project stream:

E.g., EMF's build page is very simple steps for how anyone can reproduce EMF's development environment (in which they can reproduce the Tycho build):
