Jenkins将不会保存全局工具配置

Question

Currently trying to install the groovy plugin on Jenkins, but for some reason whenever I configure a groovy installer (or ant installer, other things are also not saving), after I apply/save and leave the page, when I come back it's blank, like I did nothing. What could this be?

By the way, the Jenkins server is running on a Mac.

Answer 1

It's a bug in Jenkins, but it's only affecting the view. If you click on "Groovy installations" (or any of the other installation buttons), you'll see that the state you entered, such as name, is still there.

Note that nothing is downloaded or installed when you configure tools in "Global Tool Configuration". The tools are downloaded when you use them in a build. Therefore it's important that the name of the tool in the configuration page matches the name you use in a build.

So for example, if I where to configure Maven. I would give the maven installation a name "Maven 3" in "Global Tools Configuration", and then configure my Jenkinsfile like this

node {
    stage 'Build and test'
    env.PATH = "${tool 'Maven 3'}/bin:${env.PATH}"
    checkout scm
    sh 'mvn clean install'
}

Configuring the installer from Manage Jenkins does not actually install the tool immediately. It will be installed when you run a job that utilizes that tool. The configuration page also has a tendency to hide details when you reload the page. For example, on my server I have an Ant installation, but not a Groovy Installation. You can tell the difference on the config page by which button appears. Example Configure System Page

If you don't have anything configured, you will see an "Add {tool}" button, otherwise the button will say "{tool} installations...". You can click the "{tool} installations..." button and it should expand to show your configurations.
