我的主要目标是使用groovy来配置Jenkins和所有插件，这样我就不需要通过Web界面手动配置Jenkins，就像这里的帖子正在尝试的那样。

具体来说，我正在尝试通过groovy在Jenkins中配置Create Job Advanced插件。

当我在Jenkins脚本控制台中尝试此代码时：

import org.codehaus.groovy.runtime.NullObject;
// Jenkins instance
def descriptor = jenkins.model.Jenkins.getInstance().getDescriptorByType(hudson.plugins.createjobadvanced.CreateJobAdvancedPlugin.class);
org.kohsuke.stapler.StaplerRequest stapler = null
// Plugin Parameters
net.sf.json.JSONObject jsonObject = new net.sf.json.JSONObject();
jsonObject.put("security", false);
jsonObject.put("jobspacesinname", true);
println ("Is it a stapler request? ${stapler instanceof org.kohsuke.stapler.StaplerRequest}.");
descriptor.configure(stapler, jsonObject);

我不断收到此错误Cannot invoke method configure() on null object，不知道为什么。

Is it a stapler request? true.

如何通过groovy配置Create Job Advanced插件？

回答：

CreateJobAdvancedPlugin类似乎没有描述符。您需要从PluginManager获取插件实例，例如

import hudson.PluginWrapper
import hudson.plugins.createjobadvanced.CreateJobAdvancedPlugin
import jenkins.model.Jenkins
PluginWrapper wrapper = Jenkins.instance.pluginManager.getPlugin(CreateJobAdvancedPlugin)
CreateJobAdvancedPlugin plugin = wrapper.getPlugin() as CreateJobAdvancedPlugin
