Set GOPRIVATE for golang build & test

[misterikkit]

Is there any way to specify environment variables to the go toolchain? Specifically, I work across a set of git repos hosted on a private server, and must set GOPRIVATE=my.server.domain.name for builds to work at all.

I would assume this gets configured in pants.toml, but I did not find a concise listing of the configuration options in go support. (I also saw nothing relevant in go_binary)

Thanks in advance!

You can set env vars for all processes in pants.toml, using this option: https://www.pantsbuild.org/docs/reference-subprocess-environment#env_vars

It's not go-specific, but there is probably no harm in setting GOPRIVATE on processes that don't care about it

Is this true? On main:

$ git grep SubprocessEnvironment
src/python/pants/backend/python/util_rules/pex_environment.py:from pants.core.util_rules.subprocess_environment import SubprocessEnvironmentVars
src/python/pants/backend/python/util_rules/pex_environment.py:    subprocess_env_vars: SubprocessEnvironmentVars,
src/python/pants/core/util_rules/subprocess_environment.py:class SubprocessEnvironment(Subsystem):
src/python/pants/core/util_rules/subprocess_environment.py:class SubprocessEnvironmentVars:
src/python/pants/core/util_rules/subprocess_environment.py:    subproc_env: SubprocessEnvironment.EnvironmentAware,
src/python/pants/core/util_rules/subprocess_environment.py:) -> SubprocessEnvironmentVars:
src/python/pants/core/util_rules/subprocess_environment.py:    return SubprocessEnvironmentVars(

Yikes, I assumed that this was applied to every Process. If this is not the case then the docstring is a huge lie.

@benjyw Thanks for the quick response! I'm getting inconsistent results trying this, which tells me I'm holding it wrong. Will experiment further.
