Dependencies between extensions

[roded]

Hello,
I have a JUnit 5 extension which provides injectable FTP connections to tests.
I'd like to create a new extension which depends on the first extension and uses it to get FTP connections.
I understand that I extensions can communicate via the Store, but how can I define a dependency between the extensions so that the FTP pool will always be available for the dependent extension?
Thanks!

There's no way to declare a dependency between two extensions. Registration order is preserved, though. Thus, if you register them in the desired order they will be called in that order. If that is too brittle, you can register an "orchestrating" extension instead of the individual ones and delegate to them.
