You may add a step in the first project to trigger job of another project via restful api:

Big thanks! Can you write some simple examle .onedev-buildspec.yml to sent by api?

No need to write this file manually. Just add a command build step from GUI running in a docker image with curl, and then call curl to do the job as demonstrated in the api doc.

Can i do this with step "Execute Commands" , past in to a curl command?

Yes course

I have this error : This step can only be executed by server shell executor or remote shell executor

Your job is currently executed by a docker executor, and all command steps need to be executed inside a container. Please turn on the option "Run In Container", and specify an image with curl pre-installed, or simply specify as "ubuntu", and run below commands:

apt update
apt install -y curl
curl -G -X ...
