Hi,
I am still using Gazebo7 on Xenial / Kinetic and cannot reproduce your error.
This error means that the ROS API is not loaded prior to the plugins.
You should see more or less this sequence:
process[gazebo-2]: started with pid [6227]
process[gazebo_gui-3]: started with pid [6232]
process[brov/spawner-4]: started with pid [6237]

process[brov/thrusters/joint_state_publisher-6]: started with pid [6239]

The important line is the [ INFO] [1508920236.079088013]: Finished loading Gazebo ROS API Plugin as it shows Gazebo has loaded its ROS API and has executed ros::init.
I'll give it a try in a virtual machine.
I also get errors when trying to use Gazebo8 (with Kinetic).
After some reading it appears that using Gazebo8 for ROS is not recommended.
According to this page, you have to install ros-lunar-gazebo8-ros-pkgs by hand if you want to stick with Gazebo8. However I recommend using the LTS versions (at the moment: Xenial / Kinetic / Gazebo 7).
Tys @oKermorgant, I'll take a look and reply my test with gazebo ros pkg.
This plugin is awesome, congrats !
