Hello Julian and Simon,

I'm trying to test this patch but I find a problem with package version
specification

If I try to _build_ maven with my current guix specifying a version I
get this:

--8<---------------cut here---------------start------------->8---

$ LC_ALL=C guix build -n --no-substitutes maven --with-version=maven=3.8.6
guix build: warning: could not find version 3.8.6 of 'maven' upstream
The following derivations would be built:

--8<---------------cut here---------------end--------------->8---

Am I doing something wrong?

I applied the patch and in my guix dev env I try to build maven:

--8<---------------cut here---------------start------------->8---

giovanni <at> roquette [genv]\:  ./pre-inst-env guix build -n --no-substitutes maven
/gnu/store/9cx7sijbc9n1fvq528qysh33v6aqb3d9-maven-3.8.6

--8<---------------cut here---------------end--------------->8---

How can I "force" the build of a package already stored in /gnu/store?

Obviously building with --with-version does not work here, also:

--8<---------------cut here---------------start------------->8---

giovanni <at> roquette [genv]\: ./pre-inst-env guix build -n --no-substitutes maven --with-version=maven=3.8.6
guix build: warning: could not find version 3.8.6 of 'maven' upstream
/gnu/store/9cx7sijbc9n1fvq528qysh33v6aqb3d9-maven-3.8.6

--8<---------------cut here---------------end--------------->8---

[...]

What am I missing?

Thanks! Gio'
