MATLAB error on ROS custom message

I am trying to generate a custom ROS message in MATLAB, and I have followed all sorts of tutorials. However, I am getting the following error:

* What went wrong:

Could not resolve all dependencies for configuration ':mrs_mavros_interface:runtime'.

> Could not resolve org.ros.rosjava_messages:mavros_msgs:[0.0,).

Required by:

org.ros.rosjava_messages:mrs_mavros_interface:0.0.5

> No cached version of org.ros.rosjava_messages:mavros_msgs:[0.0,) available for offline mode.

* Try:

Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

BUILD FAILED

Can someone please help me with it.

Hi HemJyothi Das,

Which version of MATLAB that you are using ?

From the error message, i understand that you are using MATLAB version earlier than R2020b.

To Use custom ROS message and service types in MATLAB and Simulink, you need install ROS Toolbox interface for ROS Custom messages. Please find thw following link

https://www.mathworks.com/matlabcentral/fileexchange/49810-ros-toolbox-interface-for-ros-custom-messages

If you have already installed the package, please share the custom message package.

Thanks,

Jagadeesh k.

Thanks @Jagadeesh Konakalla for your response. The problem is solved now. The message mavros_msgs was missing as a dependency. After adding it to the list of custom messges and using the usual process of message conversion of ROS custom messages, the problem is fianlly solved.
