ROS2 Messages and Service Generation Problem [closed]

edit

18.04/bouncy

I am generating a bunch of messages and one service in a package. It seemingly builds fine.

rosidl_generate_interfaces(
    ${PROJECT_NAME}
        msg/Path2D.msg
        ...
        msg/Point2D.msg
        srv/SwitchPlugin.srv
    DEPENDENCIES
        std_msgs
        geometry_msgs
)

However, when building a separate message package that depends on this one, i get the following error.

I've never seen this before with the service generating a Request message, but it makes sense. How do I fix it?
