Description
This PR is in the context of this PR on the core Collector modifying
make check-contrib
to use the latest version ofmdatagen
.The
make generate
commands currently starts by compiling build tools in the.tools
folder, then itgo install
s mdatagen globally for use ingo:generate
. Unfortunately,go install
does not take into account the version ofmdatagen
referenced ininternal/tools/go.mod
. This means it isn't possible to generate using the local version ofmdatagen
for testing, even withreplace
statements.This PR fixes this by prepending
.tools
to the$PATH
before running the generate command, which makesgo:generate
use the version ofmdatagen
in that folder instead of a global one.(Originally, this PR also added a new
modgenerate
target inMakefile.Common
, to allow running generate commands on a specific group of modules instead of all of them for efficiency reasons. After discussing it with @mx-psi, we decided to hold off on that change for a later PR, as it warrants further discussion.)
