Tycho now uses Github Discussions:

https://github.com/eclipse/tycho/discussions

so oyu probably want to open your request there.

Apologies if this is not the right mailing list. The Tycho forum is
closed and the Tycho-user mailing list is shut down. I am hoping for a
little help and didn’t know where else to turn.

I followed the example itp04 to build pom files for all my plugins,
features, and products.
https://github.com/eclipse/tycho/tree/master/demo/itp04-rcp
<https://github.com/eclipse/tycho/tree/master/demo/itp04-rcp>

Everything appears to go well until the default-assemble-repository step
of the product. I am getting this error message:

[INFO] --- tycho-p2-repository-plugin:2.7.4:assemble-repository
(default-assemble-repository) @ product.core ---

for help.

I read the wiki page and understand that p2 is not finding the
edu.illinois.mobius.feature feature. However, when I go and look at the
result of that step, it looks like it is being built. Here is the output
from that step:

[INFO] ----------< edu.illinois.mobius:edu.illinois.mobius.feature

How can I debug this further? Where should the produced feature be on
the disk other than the jar file in the output?

Thanks in advance!
