Re: [papyrus-rt-dev] Setting up the developer environment with Oomph fai

[Ernesto Posse <eposse@xxxxxxxxxxxxx>]

My experience is that this sort of error happens often. My theory is that maybe while running Oomph the setup tries to resolve the dependencies defined in the Papyrus-RT nightly p2 repo might happen at the same time as a a build job is replacing the repo.

If that really is the problem, perhaps if we had an integration p2 repo we could make the Oomph setup point to that instead, and then the developer can update later.

In the meantime, the only workaround that I know of is to rerun the setup, and cross your fingers while praying to the Eclipse gods ;)

Also remember to update the Oomph setup from the website, to make sure you have the latest.

Hi Rémi,

thanks for your feedback! Strange... I'll probably retry in a couple of days and use my old workspace in the meantime.

Thanks and best wishes,

Philip

Hi Philip,

I ran the install using the oomph profile a few days ago, and the installation was successful. 

Maybe the repo was not available while you were installing your environment. The only noticeable difference since I installed my version is the addition of the o.e.p-rt.umlrt.uml plugin, but it is part of the umlrt.profile feature as expected and install for RCPs seems to be also OK [1].

Regards,

Rémi

Hi everyone,

I tried to set up a new dev environment on my machine following the developer guide using the latest Eclipse installer, but the installation failed with the following message:

Last time I tried it a couple of month ago, this was working fine. Is this a known problem?

Thanks and best wishes,

Philip
