Hi Sébastien,
To add to Ian’s answer, $HOME is not defined by default in build
environments.
Its possible that adding a phase like the following example to your
package can provide an easy fix.
(add-before 'build 'set-home
(lambda _
(setenv "HOME" "/tmp")))
The root cause of your issue being that "${user.home}/.jmri" would
expand to /.jmri since $HOME is not set.
Good day,
Noé
