They fail with e.g.

Downloading https://queue.taskcluster.net/v1/task/U6FTqzMgQfqW2qa7z3HKjA/artifacts/public/build/maven/org/mozilla/geckoview/geckoview-x86/70.0.20190814025315/geckoview-x86-70.0.20190814025315.aar
Download failed: HTTP Error 404: Not Found

Because the actual artifact is https://queue.taskcluster.net/v1/task/VmHZ7BNWQ7qwfEDEalPZ9g/runs/0/artifacts/public/build/maven/org/mozilla/geckoview/geckoview-nightly-try-x86_64/70.0.20190814010535/geckoview-nightly-try-x86_64-70.0.20190814010535.aar

(geckoview vs geckoview-nightly-try)

My guess is that this is a regression from Bug 1563711.

Looks like jlorenzo is PTO, but I'll NI him to investigate further.

glandium, if you need this fixed more quickly, I can look. My guess is that we're not using a channel correctly somewhere.

This is more serious, or at least causes more problems. The Ns builds in https://treeherder.mozilla.org/#/jobs?repo=try&selectedJob=265192848&revision=ff153ea7ebe3438faea92dc95ccfdb6a16dc6132 are busted for the same reason (I think): the builds produce, e.g.,

public/build/maven/org/mozilla/geckoview/geckoview-nightly-try-x86/71.0.20190905165358/geckoview-nightly-try-x86-71.0.20190905165358-javadoc.jar

but the CoT fails with

scriptworker.exceptions.CoTError: 'path public/build/maven/org/mozilla/geckoview/geckoview-x86/71.0.20190905165358/geckoview-x86-71.0.20190905165358-javadoc.jar not in signing:build QFQth-1KRnO8cdDSal0_mw chain of trust artifacts!'

Patch is on its way 🙂

Is this something which needs a Beta approval request?

Bug 1573751 - Fix geckoview nightly signing on try r=nalexander

Good eye! I agree it's worth uplifting to beta.

Beta/Release Uplift Approval Request

• User impact if declined: None to end-users. Geckoview developers will get Android signing jobs busted if they attempt to run try against beta.
• Is this code covered by automated tests?: Yes and no. This code impacts CI so it's exercised every time something/someone asks for a signed geckoview beta. Although, there is no automated tests for this kind of CI config.
• Has the fix been verified in Nightly?: Yes
• Needs manual test from QE?: No
• If yes, steps to reproduce:
• List of other uplifts needed: None
• Risk to taking this patch: Low
• Why is the change risky/not risky? (and alternatives if risky): The patch just impacts try on beta. Other branches aren't touched.
• String changes made/needed: None
