[tycho-user] Skip assemble-repository to build products?

[Mickael Istria]

Hi,

I'm thinking about possible ways to speed up the EPP builds (currently
taking ~4h on Eclipse.org CI).
It seems like it's spending a lot of time in the various
"assemble-repository" goals of each package. As those repositories are not
redistributed, it might work to simply get rid of that step or to minimize
its work.
So I've got a few questions:
1. Does anyone know whether we can hope materialize-products to work if
there has been no "assemble-repository"? It looks like yet according to the
doc, but additional feedback would be welcome
2. If 1. is doable, what is a recommendation for the the best way to skip
the assemble-repository execution (since this one has no 'skip' flag).

Thanks in advance,

[Sievers, Jan]

hard to tell what could be optimized without concrete build logs and links to source code repo.

I think in principle it should be possible to skip assemble-repository (e.g. if all you are interested in is a product tarball) but it's not right now.
One thing you can try is to skip copying artifacts
https://eclipse.org/tycho/sitedocs/tycho-p2/tycho-p2-repository-plugin/assemble-repository-mojo.html#createArtifactRepository

Another idea is to put multiple products in the same eclipse-repository module (not sure if you have that already)

Hi Jan,

I've opened https://bugs.eclipse.org/bugs/show_bug.cgi?id=518813 (with a
patch). For EPP it seems to be a good path: I can skip the
assemble-repository step (associate its execution with an empty phase) and
then use this mojo with the tweak added to mirror a subset of TP+current
module.
So as soon as this is approved in Tycho, EPP can take advantage of it and
save a lot of time.

Cheers,
