使用 Groovy 脚本的 SCP 插件配置

Question

我在使用 Groovy 脚本配置 Jenkins SCP 插件时遇到问题。我尝试了几种方法，但未能成功将 SCP 站点条目添加到 Jenkins 配置中。

我尝试了以下方法：

import be.certipost.hudson.plugin.*
import jenkins.model.*
import hudson.model.*
import hudson.utils.*
import hudson.util.CopyOnWriteList
import org.kohsuke.stapler.StaplerRequest
import org.kohsuke.stapler.QueryParameter;

// Get the Jenkins instance.
def instance = Jenkins.getInstance()

// Get the Git plugin descriptor.
pluginURL = "be.certipost.hudson.plugin.SCPRepositoryPublisher"
def desc = instance.getDescriptor(pluginURL)

// Create a new SCPSite.
scpsite = new SCPSite('hostname', '22', 'username', 'password', 'rootRepositoryPath')

// Store it to an arraylist.
ArrayList<SCPSite> siteList = new ArrayList<SCPSite>();
siteList.add(scpsite)

// Also try to store it in a CopyOnWriteList.
lossitios = new CopyOnWriteList<SCPSite>()
lossitios.add(scpsite)

每种方法都失败并出现异常，要么无法访问 replaceBy() 方法，要么我得到 UnsupportedOperationException。

// Update the configuration (both approaches fail)
//desc.sites.replaceBy(siteList)
desc.sites.replaceBy(lossitios)
desc.save()

我也尝试使用我在此处找到的方法 (https://github.com/jenkinsci/slack-plugin/issues/23)：

scp = instance.getExtensionList(
  be.certipost.hudson.plugin.SCPRepositoryPublisher.DescriptorImpl.class
)[0]
def params = [
  hostname = "hostname",
  port = 22,
  username = "username",
  password = "password",
  rootRepositoryPath = "rootRepositoryPath",
]
def req = [
  getParameter: { name -> params[name] }
] as org.kohsuke.stapler.StaplerRequest
desc.configure(req, null)
desc.save()

我使用replaceBy()方法时遇到的异常是：

groovy.lang.MissingMethodException: No signature of method: [Lbe.certipost.hudson.plugin.SCPSite;.replaceBy() is applicable for argument types: (java.util.ArrayList) values: [[be.certipost.hudson.plugin.SCPSite@44605afb]]

Script1.run(Script1.groovy:53) 是我对desc.configure(req, null) 的呼叫。

Answer 1

最近不得不解决这个问题，问题出在您正在创建的请求中。如果你在https://github.com/jenkinsci/scp-plugin/blob/7ce951d1a3861c6837d71f87cbb553feb7b6c222/src/main/java/be/certipost/hudson/plugin/SCPRepositoryPublisher.java#L318看他插件的源代码

    @Override
    public boolean configure(StaplerRequest req, JSONObject formData) {
        sites.replaceBy(req.bindJSONToList(SCPSite.class,
                                           formData.get("sites")));
        save();
        return true;
    }

您需要提供对 StaplerRequest 对象的调用是 bindJSONToList，其次您还需要提供一个 JSONObject，它可以调用 '.get("sites")'。

以下代码解决了这两个问题（可能有一些改进，因为我只是将它们放在一起以解决相同的问题）：

import be.certipost.hudson.plugin.*;
import org.kohsuke.stapler.StaplerRequest;
import net.sf.json.JSONObject;

def instance = Jenkins.getInstance()

pluginURL = "be.certipost.hudson.plugin.SCPRepositoryPublisher"
def desc = instance.getDescriptor(pluginURL)

params = [
  sites: [
    // one site per line as an array of options
    // displayname, hostname, port, username, password, keyfile, path
    ["site-name", "hostname", "22", "username", "password", null, "/root/path"]
  ]
]

scp_sites = params['sites'].collect { it -> it as SCPSite }

// notice the only call we are providing as for the the request
// object is bindJSONToList, and we don't care about the
// original arguments since just returning predefined data
def req = [
  bindJSONToList: { klazz, data -> scp_sites }
] as org.kohsuke.stapler.StaplerRequest

desc.configure(req, params as JSONObject)
desc.save()
