I am getting the following error when i try triggering a build using the following command:
curl http://jenkins_server:port/jenkins/job/job_name/build?token=token_name>
I install Build Token Root Plugin to solve this issue before
https://wiki.jenkins-ci.org/display/JENKINS/Build+Token+Root+Plugin
Then as the same, setup Authentication Token
Finally, either use curl to trigger remote build (Be careful the escape character "\")
curl http://JENKINS_URL/buildByToken/build?job=JOB_NAME\&token=TOKEN_NAME
or paste the URL to your browser (No needs escape character "\")
http://JENKINS_URL/buildByToken/build?job=JOB_NAME&token=TOKEN_NAME
If you see Succeed, it means that trigger remote Jenkins successfully.
Note that, you don't have to setup build, discover, and read rights on Job
