Details
This ticket tracks turning the Gradle dependency fetching bits of the existing Deps task into a proper toolchain task. I think this will be tricky 'cuz the existing Deps task is fundamentally "build-like": it configures and builds a tree (with !COMPILE_ENVIRONMENT) before running some Gradle tasks. That doesn't fit that well with the existing toolchain machinery, which expects to run a script in a non-build environment. But let's see how we do!
The jobs at https://treeherder.mozilla.org/#/jobs?repo=try&revision=cd13a02b190be61489106f1a38a26c9882dc7a0a are close to working, but: [task 2017-10-03T22:34:08.776Z] 22:34:08 INFO - 0:06.30 403 Client Error: Forbidden for url: https://queue.taskcluster.net/v1/task/V8wk0GL4TaOfTeyNoSRlyQ/artifacts/project/gecko/android-sdk/android-sdk-linux.tar.xz dustin: that must mean our business with the TC scopes didn't work. Can you take a look at that hacky patch series and suggest where I might have gone wrong?

glandium suggested using the Task Cluster proxy in the relevant mach command, but a try push with that still gives [task 2017-10-03T22:58:52.078Z] 22:58:52 INFO - 0:04.54 403 Client Error: Forbidden for url: http://taskcluster/queue/v1/task/V8wk0GL4TaOfTeyNoSRlyQ/artifacts/project/gecko/android-sdk/android-sdk-linux.tar.xz Maybe my paths are wrong?
I'll be away for a while - maybe bstack can help?

Was this sorted out by the investigation from yesterday or is it still an issue?

I _think_ I've figured out: https://treeherder.mozilla.org/#/jobs?repo=try&revision=59ac3c431b3c6e33e4b49fba7c1a827c0982ec97&selectedJob=135245649 is downloading android-sdk-linux... which is private! I did have to work around the issue fixed by Bug 1405889 since that fix isn't deployed yet, but I was able to make the taskcluster-proxy /bewit endpoint work \o/ Thanks for checking in, bstack.

As I said, I tried to let the toolchain task override the sparseprofile set at http://searchfox.org/mozilla-central/source/taskcluster/taskgraph/transforms/job/toolchain.py#152, but I had very difficult to understand errors: missing files that were actually there; corrupt checkouts galore; etc. I found this as a work-around but want to get your opinion on this hack, and how we should address this in general. That is, what do we do for toolchain tasks that require larger and larger subsets of the source checkout?

That's a good question, and I don't have an answer to it :( I don't know how much flexibility there is in the underlying mercurial feature.

We use a different set of caches depending on whether a sparse checkout is being used. And run-task + robustcheckout should have sufficient checks to ensure any accidental mismatch between sparse checkouts and caches is detected. The sparse changes in this series LGTM.
