Since Jenkins 2.264 I am encountering an error when either trying to modify the configuration of a job with a "Build periodically" trigger or when trying to add a "Build periodically" trigger to any job. The error - net.sf.json.JSONException: JSONObject["hudson-triggers-TimerTrigger"] is not a JSONObject - happens when I click on Save or Apply and the job configuration is not saved.
Downgrading to 2.263 resolves the error but that is not a long term solution (especially since I already upgraded some plugins that are now broken because they require a newer Jenkins version ... ). After 2.264 I tried again with 2.269 today and I still run into this error. In Jenkins' log I can see the JSON with the job configuration that fails to parse and it contains this: "hudson-triggers-TimerTrigger": true, "spec": "H 1 * * *", based on the exception I suspect that this should be "hudson-triggers-TimerTrigger": { "spec": "H 1 * * *" } instead but I have no idea how I can fix this at my end. If anyone knows a solution or a workaround I'd greatly appreciate it. I would report this at Jenkins Jira, but I can't login there :/ Thanks, Inga -- You received this message because you are subscribed to the Google Groups "Jenkins Users" group.
