[kaichie]

Completion Criteria

Implementation Notes / Suggestions

• Add an optional flag to skip rosdep install here?

If dependencies are already installed, then rosdep should be pretty quick and will simply install nothing. Nonetheless, a pull request adding this feature would be welcome!

@christophebedard I have created the PR, thanks for getting back so quickly!

It will be mainly used to fail the build if the core dependencies are not in the image. However, it will not fail for the missing <exec_depend> dependencies. What do you think of adding another step to check the missing dependencies when the action is used with skip-rosdep-install?

[christophebedard]

Tests should fail if <exec_depend> dependencies are missing, no?

Tests should fail if <exec_depend> dependencies are missing, no?

True if the package unit tests are covering the component. Just thinking for cases where test coverage are minimum(only testing for linting/formatting).

[christophebedard]

That isn't ideal, but that's true. I think it would depend on what that <exec_depend> dependencies check would look like then. If it's simple enough, then we could consider adding it (optionally).

[kaichie]

Added the dependencies check using rosdep check as an optional step when used with skip-rosdep-install. Please let me know if it sounds good.
