我打算构建名为 ros2-seminar-examples.git 的包
我 git clone https://git/ros2-seminar.git
并尝试 colcon build --symlink-install --packages-select ros2-seminar-examples
但它说
1.845s] 警告：colcon.colcon_core.package_selection：忽略--packages-select 中未知的包“ros2-seminar-examples” 摘要：0 个包完成 [1.52s]
所以我 colcon build --symlink-install （全部构建）
但是我收到了这样的长消息

If a package in a merged underlay workspace is overridden and it installs headers, then all packages in the overlay must sort their include directories by workspace order. Failure to do so may result in build failures or undefined behavior at run time.
If the overridden package is used by another package in any underlay, then the overriding package in the overlay must be API and ABI compatible or undefined behavior at run time may occur.
If you understand the risks and want to override a package anyways, add the following to the command line:
--allow-overriding action_tutorials_interfaces examples_rclcpp_minimal_action_client examples_rclcpp_minimal_action_server examples_rclcpp_minimal_client examples_rclcpp_minimal_composition examples_rclcpp_minimal_publisher examples_rclcpp_minimal_service examples_rclcpp_minimal_subscriber examples_rclcpp_minimal_timer examples_rclcpp_multithreaded_executor examples_rclpy_executors examples_rclpy_minimal_action_client examples_rclpy_minimal_action_server examples_rclpy_minimal_client examples_rclpy_minimal_publisher examples_rclpy_minimal_service examples_rclpy_minimal_subscriber turtlesim
This may be promoted to an error in a future release of colcon-override-check.

我看到 'msg_srv_action_interface_example' 文件夹位于 src 文件中，并且 git 克隆文件中也有相同的文件夹，我删除了 src 中的 'msg_srv_action_interface_example' 文件夹。现在我得到 1 个包失败，因为无法找到目录
