A coworker left this on my desk with a note saying a Chinese partner had given him an early iPad 3 prototype unit. I thought it was pretty funny.

It only weighs 20lbs.

I was looking for an easy way to script changing the email addresses on all of my hudson projects and didn’t find any solution on the interwebs. So, I though I would post mine for others to use.

Essentially, just go to the groovy console in hudson/jenkins (under Manage -> Script Console) and enter what ever groovy you like. The javadoc for the API can be found at: http://hudson-ci.org/javadoc/index.html

In my case, I needed to change the email address for every job’s notification settings. So, I used the following script:

import hudson.model.*

int count=0;
Hudson.instance.items.each{ item ->
  item.each{ job ->
     def configFile = new File(item.getConfigFile().toString())
     def config = configFile.text
     if(!config.indexOf("<recipients>")){
              println "$job Not Updated"
     }else{
         def regex = "</recipients><recipients>[^< ]*</recipients>"
         config = config.replaceAll(regex, "</recipients><recipients>somegroup@nowhere.com</recipients>")
         configFile.write(config)
         count++;
     }
  }
}
println "Updated $count Jobs"
