Prepopulate .m2 and .grapes for most used Fuse versions #1254

When creating the first Fuse project, a lot of time is required mainly downloading artefacts. (can be 15-20 minutes even with reasonable connection speed). I'm wondering if it would be possible to "hide" this time in the installer when installing Fuse Tooling.

Would it be possible?

pre-building an offline repository and installing it (I know that fuse is providing some https://access.redhat.com/documentation/en-us/red_hat_jboss_fuse/6.3/html/integration_guide/transtools)
calling a kind of mvn on a basic Fuse example?

What do you think?

That would require a little work of course, but it is possible. What would be required is:

Add maven into list of installable components under Java channel with detection;
download maven repo for Fuse from developers.redhat.com download manager service (not access.redhat.com) as part of fuse installer or as separate one;
configure repo to be used by maven.

@apupier What do you mean by "calling a kind of mvn on a basic Fuse example?" ?

it is an alternative, instead of downloading the offline repo, the idea would be to call maven a one Fuse example which will download and install dependencies in the local .m2 of the user.

I'm not even sure that Maven is required. Currently in Fuse Tooling, it is using the embedded Maven Runtime of m2e. In case we need a Maven call, maybe we can provide a specific "eclipse application" to call Maven from inside JBoss Tools. In case just the repo is copied/installed, Maven might not be required. (seems to be the easiest solution but is it safe?)

as the release cycle of Fuse on one side and Fuse Tooling/DevStudio on the other side are different. It would be nice to be able to change the offline repositories used during installation.

That is possible. I did implement something similar in past as an experiment, but have not finished that yet (see https://github.com/redhat-developer-tooling/developer-platform-install/pull/811). Implemented approach would require to publish 'requirement.json' for download on developer portal under devsuite when we want to force installer to download new releases without full installer rebuild.
