Hi Dustin,

the ROS support in the deployer's import operation was removed in toolchain
2.7. The deployer itself only imports the package mentioned in the argument
and nothing else.
In order to import recursively following the <plugin_depend> tags in the
package.xml files you have to

1. Import the rtt_ros package with the Deployer's import operation:
import("rtt_ros")

2. Call the ros.import operation in the newly added global service ros:
ros.import("my_message_package_msgs")

In rttlua this would correspond to the following code:

depl:import("rtt_ros")
rtt.provides("ros"):import("my_message_package_msgs")
