License Question - Dual License

[Tron731]

When I review your marketing materials, your website states that the tool is a ‘dual-license’ Apache 2.0 and MPL 2.0, suggesting to me that I can select either Apache or MPL well using the tool within my product. However, the attached license file suggests that the license is a mix of MPL, BSD and MIT. I’m not sure if we’re looking in the right spots so if you could please provide us with clarity, it would be greatly appreciated.

Hello -

If you search the RabbitMQ source code, you can see where that license file comes from:

git clone https://github.com/rabbitmq/rabbitmq-server.git
cd rabbitmq-server
$ git grep -i 'bsd 2-clause'
packaging/common/LICENSE.tail:25:The BSD 2-Clause license is as follows:

OK, so the file is called LICENSE.tail. Here is how it is used:

$ git grep 'LICENSE\.tail'
Makefile:260:   $(verbose) cat packaging/common/LICENSE.tail >> $@/LICENSE

That's interesting, what is in the Makefile on line 260:

https://github.com/rabbitmq/rabbitmq-server/blob/main/Makefile#L260-L263

It looks like LICENSE.tail is appended to the overall LICENSE file. Most likely, this is due to a dependency of RabbitMQ that uses the "BSD 2-clause" license. It does not change RabbitMQ's license at all, which is clearly stated here:

https://github.com/rabbitmq/rabbitmq-server/blob/main/LICENSE

@Tron731 oh, and I didn't realize that we explicitly suggest using the rabbitmq-core@ email address here:

https://github.com/rabbitmq/rabbitmq-server/blob/main/LICENSE#L7-L8

Thank you for opening this discussion, because hopefully it will help someone else if they have a question.
