Question

我一直在尝试创建我的第一个jenkins插件。一切都很好，除了重新启动jenkins服务后全局配置不会持久。

只要服务未重新启动，配置就可以保存。

全局配置果冻文件......

<j:jelly xmlns:j="jelly:core" xmlns:st="jelly:stapler" xmlns:d="jelly:define" xmlns:l="/lib/layout" xmlns:t="/lib/hudson" xmlns:f="/lib/form">

Jenkins uses a set of tag libraries to provide uniformity in forms.
To determine where this tag is defined, first check the namespace URI,
and then look under $JENKINS/views/. For example, <f:section> is defined
in $JENKINS/views/lib/form/section.jelly.

It's also often useful to just check other similar scripts to see what
tags they use. Views are always organized according to its owner class,
so it should be straightforward to find them.
-->
<f:section title="Hello World Builder">
  <f:entry title="French" field="useFrench"
    description="Check if we should say hello in French">
    <f:checkbox />
  </f:entry>
</f:section>
</j:jelly>

保存后，jenkins正在构建名为

的配置文件

examplePlugin.examplePlugin.HelloWorldBuilder.xml

使用内容假

描述符本身如下。

// Overridden for better type safety.
// If your plugin doesn't really define any property on Descriptor,
// you don't have to do this.
@Override
public DescriptorImpl getDescriptor() {
    return (DescriptorImpl)super.getDescriptor();
}

/**
 * Descriptor for {@link HelloWorldBuilder}. Used as a singleton.
 * The class is marked as public so that it can be accessed from views.
 *
 * <p>
 * See <tt>src/main/resources/hudson/plugins/hello_world/HelloWorldBuilder/*.jelly</tt>
 * for the actual HTML fragment for the configuration screen.
 */
@Extension // This indicates to Jenkins that this is an implementation of an extension point.
public static final class DescriptorImpl extends BuildStepDescriptor<Builder> {
    /**
     * To persist global configuration information,
     * simply store it in a field and call save().
     *
     * <p>
     * If you don't want fields to be persisted, use <tt>transient</tt>.
     */
    private boolean useFrench;

    /**
     * Performs on-the-fly validation of the form field 'name'.
     *
     * @param value
     *      This parameter receives the value that the user has typed.
     * @return
     *      Indicates the outcome of the validation. This is sent to the browser.
     */
    public FormValidation doCheckName(@QueryParameter String value)
            throws IOException, ServletException {
        if (value.length() == 0)
            return FormValidation.error("Please set a name");
        if (value.length() < 4)
            return FormValidation.warning("Isn't the name too short?");
        return FormValidation.ok();
    }

    public boolean isApplicable(Class<? extends AbstractProject> aClass) {
        // Indicates that this builder can be used with all kinds of project types 
        return true;
    }

    /**
     * This human readable name is used in the configuration screen.
     */
    public String getDisplayName() {
        return "Say hello world";
    }

    @Override
    public boolean configure(StaplerRequest req, JSONObject formData) throws FormException {
        // To persist global configuration information,
        // set that to properties and call save().
        useFrench = formData.getBoolean("useFrench");
        // ^Can also use req.bindJSON(this, formData);
        //  (easier when there are many fields; need set* methods for this, like setUseFrench)
        save();
        return super.configure(req,formData);
    }

    /**
     * This method returns true if the global configuration says we should speak French.
     *
     * The method name is bit awkward because global.jelly calls this method to determine
     * the initial state of the checkbox by the naming convention.
     */
    public boolean getUseFrench() {
        return useFrench;
    }
}

为什么在重启时不重新加载的任何帮助都会非常有用，因为这似乎是由maven原型创建的示例项目的问题。

Answer 1

所以这是hello world应用程序的问题。您需要在构造函数中定义要加载配置。

public DescriptorImpl(){
        load();
    }

这解决了我看到的问题，配置没有被持久化。

Jenkins HelloWorld插件在重启后不会保留配置
