Description Matthew Coleman 2022-01-16 15:41:29 UTC
Description of problem:

When running `rebar3 new app myapp`, no templates are found, so the app structure is not created and instead errors with "template not found."

Version-Release number of selected component (if applicable):

erlang-rebar3-3.14.3-3.fc35.src.rpm

How reproducible:

Always.

Steps to Reproduce:

1. `sudo dnf -y install erlang-rebar3`
2. `rebar3 new app myapp`

Actual results:

Outputs "template not found." and does not create an application directory.

Expected results:

Creating the app structure under the 'myapp` directory.

Additional info:

This is appears to be the exact bug that reached EOL here: https://bugzilla.redhat.com/show_bug.cgi?id=1919729. The issue persists.

This is marked fixed but is not fully.

 ~ $ sudo dnf upgrade --advisory=FEDORA-2022-a0bbde50cd erlang-rebar3

Confirmed installed the new package:

 ~ $ sudo dnf info erlang-rebar3

The error persists:

However, I see there are now templates in the package:

~ $ dnf repoquery -l erlang-rebar3 | grep templates

According to Rebar3 documentation, it by default looks for templates in $HOME/.config/rebar3/templates. After symlinking this directory to /usr/share/erlang/lib/rebar3-3.18.0/priv/templates, things seem to work.

~ $ ln -s /usr/share/erlang/lib/rebar3-3.18.0/priv/templates ~/.config/rebar3/template
~ $ rebar3 new

app (custom): Complete OTP Application structure.
cmake (custom): Standalone Makefile for building C/C++ in c_src
escript (custom): Complete escriptized application structure
lib (custom): Complete OTP Library application (no processes) structure
plugin (custom): Rebar3 plugin project structure
release (custom): OTP Release structure for executable programs
umbrella (custom): OTP structure for executable programs (alias of 'release' template)

However the need to do this is non-obvious and an installation of the package as-is still doesn't allow usage of templates. Should this package automatically create this symlink? It is non-obvious from Rebar3 documentation if it is possible to control the template path via environment variable or otherwise.

This message is a reminder that Fedora Linux 35 is nearing its end of life.
Fedora will stop maintaining and issuing updates for Fedora Linux 35 on 2022-12-13.
It is Fedora's policy to close all bug reports from releases that are no longer
maintained. At that time this bug will be closed as EOL if it remains open with a
'version' of '35'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, change the 'version' 
to a later Fedora Linux version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora Linux 35 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora Linux, you are encouraged to change the 'version' to a later version
prior to this bug being closed.

Comment 6 Ben Cotton 2022-12-13 16:20:22 UTC
Fedora Linux 35 entered end-of-life (EOL) status on 2022-12-13.

Fedora Linux 35 is no longer maintained, which means that it
will not receive any further security or bug fix updates. As a result we
are closing this bug.

If you can reproduce this bug against a currently maintained version of Fedora Linux
please feel free to reopen this bug against that version. Note that the version
field may be hidden. Click the "Show advanced fields" button if you do not see
the version field.

If you are unable to reopen this bug, please file a new report against an
active release.

Thank you for reporting this bug and we are sorry it could not be fixed.
