For archive's sake, let me tell my solution.
I carefully added a preprocessing command into my build steps. Before
compiling, the following command is run:
sed -E -i 's:(Version\s*=\s*)".*":\1"'$(DOCKER_CLI_VERSION)'":' \
$(@D)/cli/version/version.go \
&& sed -E -i 's:(GitCommit\s*=\s*)".*":\1"'$(shell git rev-parse
--short HEAD)'":' \
$(@D)/cli/version/version.go
The regexes match patterns in
Version = "xxx"
Format and replaces the string inside the double quotes while keeping all
the whitespaces and other relevant characters intact, so repeatedly calling
the same substitution is safe and does the expected thing. Same for the
GitCommit, except it uses a shell command instead of an environment
variable.
Happy Hacking
