Simple groovy script to upgrade active plugins when new versions are available

keep-jenkins-plugins-uptodate.groovy

jenkins.model.Jenkins.getInstance().getUpdateCenter().getSites().each { site ->
  site.updateDirectlyNow(hudson.model.DownloadService.signatureCheck)
}

hudson.model.DownloadService.Downloadable.all().each { downloadable ->
  downloadable.updateNow();
}

def plugins = jenkins.model.Jenkins.instance.pluginManager.activePlugins.findAll {
  it -> it.hasUpdate()
}.collect {
  it -> it.getShortName()
}

println "Plugins to upgrade: ${plugins}"
long count = 0

jenkins.model.Jenkins.instance.pluginManager.install(plugins, false).each { f ->
  f.get()
  println "${++count}/${plugins.size()}.."
}

if(plugins.size() != 0 && count == plugins.size()) {
  jenkins.model.Jenkins.instance.safeRestart()
}

@alecharp: This script is great.
It would be really helpful to modify the script to check if there is any way to upgrade only the plugins which have no compatibility warnings with the current Jenkins version.

@alecharp, can you share more about using the Docker image to have the latest Jenkins WAR and plugins? Could it be that you flush all existing JARs/plugins and keep appdata before updating the image?

I have made some work starting from this script. I made it detect plugins warnings or if any of them get deprecated before performing the update.
I have created a Jenkins pipeline that invokes the Groovy script and returns an alert if warnings or deprecated plugins are detected.
here is a link to the scripts

Thank you @alecharp for the inspiration 🤘

Does this fork not solve it?

Thanks for this! :)
