guix build and HTTPS does not work, but guix download does

["Björn Höfling" <bjoern.hoefling@bjoernhoefling.de>]

Hi,

I have a problem here that I don't understand. I'm trying to build
Hartmund's Java branch an a Ubuntu/Guix system and I cannot download
over HTTPS while doing guix build. But I can `guix download` and
afterwards build that package.

Here is what I'm doing:

guix pull
# I'm going into 'pure', because there is also guile installed in Ubuntu
# and I don't want any conflicts:
guix environment --pure  guix --ad-hoc gnutls nss-certs git

# This was suggested by Hartmund here:
# https://lists.gnu.org/archive/html/guix-devel/2017-04/msg00565.html
export SSL_CERT_DIR="$GUIX_ENVIRONMENT/etc/ssl/certs"
export
SSL_CERT_FILE="$GUIX_ENVIRONMENT/etc/ssl/certs/ca-certificates.crt"
export GIT_SSL_CAINFO="$SSL_CERT_FILE"

#I'm currently here:
git status
On branch WIP-maven
Your branch is up-to-date with 'goebel/WIP-maven'.

# Now let's get that build:
bjoern@alma-ubu:~/guix/guix$ ./pre-inst-env  guix build
maven-for-bootstrap #@

But then:


bjoern@alma-ubu:~/guix/guix$ ./pre-inst-env guix download

bjoern@alma-ubu:~/guix/guix$ ./pre-inst-env  guix build java-jsr305
--> works !!!

guile -c '(use-modules (gnutls))'; echo $?

In that way I at least come step by step to my goal, but why does `guix
build` fail to download?
