Expected behavior

so shoud i compile it myself on arm64 server?

Additional context

No response

It's not a bug in the plugin but a file permission issue:
{:error, {:cannot_read_enabled_plugins_file, '/etc/rabbitmq/enabled_plugins', :eacces}}

This may be caused by the images you are using (that we don't maintain) or by the deployment configuration.

[wwlleo0730]

it really really really hard to build a rabbitmq plugin

i build the plugin on my arm64 server , looks like ok now

[mkuratczyk]

What kind of problems did you have building it?

[wwlleo0730]

cause i am a Java developer and have no experience with Erlang

I find it quite challenging to set up the erlang development environment for the first time

and the error messages during the compilation process of the plugin are not very clear either

and finlly, i dont know how to build .ez file, make me crazy

[mkuratczyk]

Well, everything is hard for the first time and I agree that some Erlang messages can be quite cryptic, but we can't solve all the problems. My understanding is that you managed to build it, but if no - please share what you get right now

Fortunately about a month or so (on average) after a new RabbitMQ feature (minor) release no one really has a reason to build community plugins from source any more. There is an architecture and OS-neutral binary release that can be downloaded.

[wwlleo0730]

A few days later... I found out that the real reason is that there is no permission

It does not need to be compiled on arm64, ， just set umask and all right
