Hi,

I am trying to integrate PX4 SITL(Software-In-The-Loop) simulation into ignition gazebo.

However, when I add the plugin and start it from the world file, the plugin fails with the following error.

Warning [Model.cc:210] Non-unique names detected in XML children of model with name[x3].
[libprotobuf ERROR google/protobuf/descriptor_database.cc:57] File already exists in database: ignition/msgs/time.proto
[libprotobuf FATAL google/protobuf/descriptor.cc:1164] CHECK failed: generated_database_- 
>Add(encoded_file_descriptor, size): 
terminate called after throwing an instance of 'google::protobuf::FatalException'
what():  CHECK failed: generated_database_->Add(encoded_file_descriptor, size):

The plugin itself I am trying to use a identifal plugin as in the System Plugin Tutorial

What would be causing the exception?

The plugin itself I am trying to use a identifal plugin as in the System Plugin Tutorial. Removing the plugin from the world file allows ignition gazebo to run properly.

What would be causing the exception?
