A little about package.xml files

The package.xml is the file in your software where rosdep finds the set of dependencies. It is important that the list of dependencies in the package.xml is complete and correct, which allows all of the tooling to determine the packages dependencies. Missing or incorrect dependencies can lead to users not being able to use your package, to packages in a workspace being built out-of-order, and to packages not being able to be released.

The dependencies in the package.xml file are generally referred to as “rosdep keys”. These dependencies are manually populated in the package.xml file by the package’s creators and should be an exhaustive list of any non-builtin libraries and packages it requires.

These are represented in the following tags (see REP-149 for the full specification):
