Basic usage throws org.json.JSONException

See original GitHub issue

Probably something I’m overlooking but running the most basic example fails for me:

jenkins@5e3eb1c93a51:~$ java -jar jenkins-plugin-manager-1.1.2.jar --war /usr/share/jenkins/jenkins.war --plugin-file /var/jenkins_home/plugins.txt --verbose

I’m running this command from inside a docker container using the jenkins/jenkins:2.235.1 image.

Plugin file:

blueocean:1.23.2
configuration-as-code:1.41
gitlab-plugin:1.5.13
ssh-credentials:1.18.1
job-dsl:1.77

What I am doing wrong here?

looks like the json files

https://updates.jenkins.io/2.235/update-center.json
https://updates.jenkins.io/experimental/update-center.json contain an unexpected string at the begin on the json file: updateCenter.post({..... that causes the JSON parser to exit.

in my case a workaround was to point the command to these versions of the json files:

Here is my command with the adapted json files

java -jar ./jenkins-plugin-manager-1.1.2.jar    --plugin-file ./pluginfile.txt --verbose --jenkins-update-center https://updates.jenkins.io/current/update-center
.actual.json --jenkins-experimental-update-center https://updates.jenkins.io/experimental/update-center.actual.json
