Java.io.IOException: No X-Jenkins-CLI2-Port (jenkins cli not working)

I am trying to run the following command:

java -jar jenkins-cli.jar -s http://jenkins_URL/ --username myusername --password mypassword help

But I get an error message:

There is an official solution on the Jenkins Wiki page for the CLI .

decision

  • Go to Jenkins Management (in the Jenkins interface)
  • → Global Security Configuration
  • → "TCP port for JNLP agents": select fixed or random

To verify that this is not a username and / or password error, change this line:

 <denyAnonymousReadAccess>true</denyAnonymousReadAccess>

in

 <denyAnonymousReadAccess>false</denyAnonymousReadAccess>

in the config.xml file.

Now you can connect to your jenkins interface to debug your credentials

Do not forget to reset it to true.

For those who are watching how to do this work programmatically (unattended). You have to change

  <jenkins.CLI> <enabled>false</enabled> </jenkins.CLI>

to

  <jenkins.CLI> <enabled>true</enabled> </jenkins.CLI>

in / var / lib / jenkins / jenkins.CLI.xml and restart jenkins

If you do not understand why this fails, run a debugger in strace / dtruss , for example.

 $ strace -fs1000 -e trace=network java -jar jenkins-cli.jar -s http://localhost:8080/ help

If you have:

HTTP / 1.1 403 There was no doubt about the request.

then you need to either provide the crumb in the request or disable CSRF Protection .

Using the Jenkins CLI it still does not work when the rabbit agent is on, so you can use curl . For example (replace localhost with your Jenkins address):

  • Pay attention to the user API token ( /user/USER/configure ).

  • Get your baby:

     CRUMB=$(curl -s 'http://USER: TOKEN@localhost :8080/crumbIssuer/api/xml?xpath=concat(//crumbRequestField,":",//crumb)')

  • Calling some command (for example, a list of tasks):

     curl -H $CRUMB http://USER: TOKEN@localhost :8080/api/json
