Unable to generate logs at the specified location.

Describe the bug
I am currently working on updating Hackage builder to cabal v2 as a part of GSoC Project.
The objective was to build the package, run tests, create Haddock doc and run code-coverage.
I need the report of each of these tasks in the specified files. I tried setting the flags to make cabal write test log, build-summary, logs and docs at the specified location but it doesn't seem to work.

To Reproduce
In the root directory of a package (async in this case), I ran the following code.

$ cabal v2-build \
	--enable-tests \
	--run-tests \
	--test-log="/home/USER/haskell/test.log" \
	--haddock-for-hackage \
	--enable-doc \
	--docdir="/home/USER/haskell/" \
	--enable-coverage \
	--build-summary="/home/USER/haskell/r.report" \
	--build-log="/home/USER/haskell/r.log" \
	--remote-build-reporting=detailed \
	--report-planning-failure

Expected behavior
Specified files must have a log or report content.

System information

• Ubuntu 20.0.4
• ghc version: 8.8.3
• cabal version: 3.2.0.0

Additional context
How can we set coverage report, doc tarball location?

I think there are two independent questions here. The test stuff can at least get rum from the test command. Even without that though, the build-summary and build-log don't seem to get generated at all from my experiments? What's the correct way to get them in v2?

@jneira could you comment on the label “not our bug” (which you added): I don’t quite get why it’s not “our”…

[jneira]

me neither 😅
it was a misclick I suppose, thanks for noting it

Looks similar to #5901.

TIL about --run-tests; it seems confusing though as the documentation says "Run the package test suite upon installation" but there's no installation if you pass it to cabal build; it also mentions a hash maybe it means the store? It sounds dangerous to mix up installation with the cabal store as they are different concepts.
