./setup-dev-env.sh

# Use vcstool to import more repositories
mkdir src
vcs import src < autoware.repos

# Install dependent ROS packages
source /opt/ros/galactic/setup.bash
rosdep update
rosdep install -y --from-paths src --ignore-src --rosdistro $ROS_DISTRO

# Build the workspace
colcon build --symlink-install --cmake-args -DCMAKE_BUILD_TYPE=Release
```

```

2. Update the repository
