Re: [tycho-user] Strange behavior jenkins Vs local

[Tristan FAURE <faure.tristan@xxxxxxxxx>]

We found a workaround

The waiting threads were "download" threads that could not get dependencies (air gap environment) and blocked the main process

It worked in the docker because we ran it in a second time and dependencies were downloaded and stored in the cache

Using usedefaultp2mirrors (https://wiki.eclipse.org/Tycho/FAQ#How_do_I_disable_P2_mirrors.3F) to false fixed the issue but we have to found a better solution

Maybe we missed it but he could be nice to have time out options or debug options to see dependencies that are downloading.

Hi Mickael,

Thanks for your answer,

We have thought about that but generally when it occurs, the jvm or the docker crashes.

We made our dumps thanks to a connection to a blocked pod and we were able to run the build inside the blocked Pod, so basically in one container, we had one blocked build (subject of the topic) and one build that passed (Oo), so we imagine the resources were ok

Regards

Tristan FAURE

Hi Tristan,

Could it be that you reached some limitations (cpu, ram, disk
space...) of you containers/pod?
