Dependency on actionlib when building .action files

edit

• Up to today's latest wiki page of actionlib lists actionlib as a required dependency with actionlib_msgs to build a package that includes .action files, along.

• However, in Catkin's doc (melodic) only actionlib_msgs is a required dependency.

  To generate actions, add actionlib_msgs as a dependency

Which one is correct?

UPDATE1: Responding to the comment from @Dirk Thomas:

The referenced wiki page does not only mention building a package with .action files but also contains examples how to use the action server / client. Therefore I would highly suggest to revert your change since it will make the page incomplete / incorrect.

I still think the wiki should present only the minimal dependency example first, so showing dependency on actionlib_msgs suffices because:

• The portion of wiki I referred to is specifically under ".action file" section.
• It's not official AFAIK, but my understanding is the practice in ROS is to separate message/service/action definition files in a designated package (e.g. #q11835). For a package that contains .action but no code, adding a dependency on action_msgs should be enough, according to your answer.
  • Of course creating a package that contains both .action files and code that depends on actionlib api is not restricted at all, but I'm not sure if the actionlib's wiki page needs to present that info, let alone in ".action file" section.
