Import ros2 source package with version info

Hi,

I am compiling ros2 source package to debian 11 platform 

vcs import --input https://raw.githubusercontent.com/ros2/ros2/humble/ros2.repos

This outputs 

repositories:
  ament/ament_cmake:
    type: git
    url: https://github.com/ament/ament_cmake.git
    version: humble
  ament/ament_index:
    type: git
    url: https://github.com/ament/ament_index.git
    version: humble
...
...

There is no version specified for each package. This poses a challenge, that every single time i run my ci/cd pipeline, it pulls the latest packages. Is there are any other way or other tools where I can download the packages along with the versions.

Thanks

UPDATE: As in comment section, this answer may not offer a straight-forward resolution to the OP's problem. Yet, in a hope that it gives some generic detail about vcstool's usage that may not be well documented, I keep it posted.

There is no version specified for each package.

There ARE versions specified. In the ament/ament_cmake example you posted, it's humble.

The "version" terminology in vcstool may be indeed a bit undocumented IINM. This field can take branch / tag of the vcs tool of the choice (e.g. git) of each repo.

So in the ament/ament_cmake example again, "humble" seems to be the name of a branch "version" on that repo, which means, yes it'll fetch the latest on that branch.

You can create your own .repos file (to e.g. modify version fields) and supply it to vcs import command by e.g. 

vcs import src < ./foo/baa.repos

As @gvdhoom mentioned. I will stick with checkout to the release branch. Is it possible to promote your comment to the accept answer ?

Ah, ok, I failed to notice the question was specifically about ros2.repos file on ros2 repo, released versions of which surely contain the specific version of each repo. I converted Gijs' comment to an answer.

You don't have to. Just checkout one of the release tags instead of a branch.

If you don't want to use a specific tag, the latest release would be available on the $ROS_DISTRO-release branches. humble-release for Humble fi.
