dependency of custom message could not be found

[Deric-W]

Describe the bug The following error occurs while building a part of this package:

C:\dev\ros2-for-unity\build\ros2_custom_msgs\rosidl_generator_cs\ros2_custom_msgs\msg\sphere.cs(31,10): error CS0246: The type or namespace name 'geometry_msgs' could not be found (are you missing a using directive or an assembly reference?) [C:\dev\ros2-for-unity\build\ros2_custom_msgs\ros2_custom_msgs_assembly\ros2_custom_msgs_assembly_dotnetcore.csproj] [C:\dev\ros2-for-unity\build\ros2_custom_msgs\ros2_custom_msgs_assembly.vcxproj]

To Reproduce Steps to reproduce the behavior:

1. Follow the tutorial (omit Num.msg and AddThreeInts.srv in msgand CMakeLists.txt)
2. add the following to ros2_for_unity_custom_messages.repos:

    src/ros2cs/custom_messages/<package_name>:
        type: git
        url: <url>
        version: humble

3. create a Windows build
4. watch it fail to build the custom package

Expected behavior The build succeeds

Desktop:

• OS: Windows 10
• ros2 distro: humble
• ros2-for-unity version: 1.2.0
• ros2cs version [e.g. git-sha 2a45785b080fffb3ae5e2f645e976a69698810f0]
• ros2 dds middleware: fastdds
• ros2 environment setup: single pc

Fix The build succeeds when adding the following to ros2_for_unity_custom_messages.repos:

    src/ros2cs/src/ros2/<package_name>:
        type: git
        url: <url>
        version: humble

I tried to reproduce the issue but without success.

I created a custom message package from the mentioned tutorial (pijaro/tutorial_interfaces) and set it up in a custom messages file ros2_for_unity_custom_messages.repos:

# NOTE: Use this file if you want to build with custom messages that reside in a separate remote repo.
# NOTE: use the following format

repositories:
#  src/ros2cs/custom_messages/<package_name>:
#    type: git
#    url: <repo_url>
#    version: <repo_branch>
#  custom_messages/<package2_name>:
#    ...
#    ...

    src/ros2cs/custom_messages/tutorial_interfaces:
        type: git
        url: git@github.com:pijaro/tutorial_interfaces.git
        version: main

then .\pull_repositories.ps1 and .\build.ps1. Build succeeded without errors.

Did you check the Windows important notices? A lot of strange errors are most often caused by Windows path restrictions.

Also, It is always a good idea to clear the build and install directories if the workspace dir changed substantially.

A full build log could be useful as well. Maybe the package and repos are correct, but the problem is that the geometry_msgs did not build successfully.

Sorry for the long delay, I cleared the build and install directories and it worked, sorry for bothering you.
