Unable to build the release version of Caddy (with the Cloudflare plugin)

[basil (Basil Hendroff)]

1. Caddy version (caddy version):

root@caddy:~ # caddy version
v2.4.0-beta.2 h1:DUaK4qtL3T0/gAm0fVVkHgcMN04r4zGpfPUZWHRR8QU=

2. How I run Caddy:

I use Caddyfile rather than JSON.

a. System environment:

TrueNAS 12.0-U3 (a FreeBSD derivative)

b. Command:

service caddy start

c. Service/unit/compose file:

n/a

d. My complete Caddyfile or JSON config:

n/a

3. The problem I’m having:

I’m currently running the latest beta release of Caddy including the Cloudflare module. For reference purposes, I’m trying to build a second instance of Caddy based on the official release (currently 2.3.0). I’m not having any success building this.

4. Error messages and/or full log output:

I don’t seem to be able to build anything but the latest beta. Version info appears to be ignored.

5. What I already tried:

I’ve also tried specifying the build version using the CADDY_VERSION environmental variable, but this doesn’t appear to work either.

root@caddy:/tmp # setenv CADDY_VERSION "v2.3.0"
root@caddy:/tmp # echo $CADDY_VERSION
v2.3.0

Known issue. The latest version of the Cloudflare plugin requires the latest beta. It’s just a downside of how Go dependency management works. See this issue (includes a workaround) but I recommend to just use the latest beta anyways.
