Cannot find a MATLAB message class for type geometry_msgs/Twist

Hello!

I follow the official steps to create custom ros messages and when I use " rosmsg list " to check it, my custom message is right here.

However, it didn't work when I use rosmessage('geometry_msgs/Twist'),

and it shows "Cannot find a MATLAB message class for type geometry_msgs/Twist".

Also, if I use the command " msginfo=rosmsg("show",'geometry_msgs/Twist') ",

it shows "Could not find definition of message type geometry_msgs/Twist. Check the spelling of the type, or use "rosmsg list" to retrieve a list of available message types."

I have the same question with you. But finally, I find the problem is just because your path contains chinese.

You can try command 'javaclasspath' to check if the path of your custom ros message contains strange characters. Maybe it's java's fault.
