Hi everyone,

I followed the instructions in the documentation to get the PX4 docker installed on my Ubuntu 22.04 machine.

I am able to successfully build the default via ./Tools/docker\_run.sh ‘make px4\_sitl’.

However when I try to run jmavsim or gazebo-classic using: ./Tools/docker\_run.sh ‘make px4\_sitl jmavsim’ I get an error: **ninja: error: unknown target ‘jmavsim’**

I have exported the PX4\_DOCKER\_REPO environment variable to use the simulation docker image via: export PX4\_DOCKER\_REPO=“px4io/px4-dev-simulation-focal” .

What am I doing wrong ? I would like to be able to run the simulators from my docker install.

Best regards and thanks for any input,  
Ioannis

The target is not available if one of the dependencies is not installed. So it sounds like either java or ant is not installed in that docker image.

Can you use another container that contains java and ant? Or just use Gazebo instead of jmavsim?

I have the same problem when I use Gazebo. Which container contains java and ant ?

Sorry, I don’t have time to look into this in more detail at the moment.
