Jenkins JobDSL种子作业由于缺少松弛的baseUrl而突然失败

我使用docker在Ubuntu 16.04上运行Jenkins 2.155

我有大约20个Jenkins JobDSL种子工作，这几年来一直没有问题

大约三天前，这些都失败了。我最终将问题缩小到缺少Slack

baseUrl

参数

起初，失败的输出是不同的，但后来我们尝试更新Jenkins以及所有插件，因为这是由于无论如何，错误改变了。但在任何情况下，我们都没有在初始错误之前进行任何更改

这是DSL脚本中的一个代码示例，尽管有许多类似的代码已经开始失败

    /**
     * Job Config
     * Each job should provide
     *    id - unique id of the job
     *    serverName - The Jenkins name of the server which needs to be connected snapshotted

    **/
    def webservers = [
        [id: 'server1-automated-snapshot', serverName: 'Server 1'],
        [id: 'server2-automated-snapshot', serverName: 'Server 2'],
        [id: 'server3', serverName: 'Server 3'],
        [id: 'server 4', serverName: 'Server 4'],
    ]

    /**
     * Job Template
     *     The job template for automated snapshot jobs. Changing this will update all the snapshot jobs.
     */
    for(webserver in webservers) {
        def jobName = webserver.id
        jobDisplayName = webserver.serverName+' automated volume snapshot'
        def jobDescription = """This job automatically runs the automated snapshot script located on the $webserver.serverName once a day."""
        job(jobName) {
            description(jobDescription)
            displayName(jobDisplayName)
            logRotator {
                numToKeep(5)
            }
            configure {
                it / 'properties' << 'hudson.plugins.disk__usage.DiskUsageProperty' {}
            }
            wrappers {
                timestamps()
            }
            triggers {
                cron('H 2 * * 1')
            }
            steps {
                publishOverSsh {
                    server(webserver.serverName) {
                        transferSet {
                            execCommand('sudo /usr/local/sbin/snapshot.sh')
                        }
                    }
                }
            }
            publishers {
                mailer('techadmin@ibboost.com', true, false)
                retryBuild {
                    rerunIfUnstable()
                    retryLimit(1)
                    fixedDelay(600)
                }
                slackNotifier {
                    room('#channel')
                    notifyAborted(true)
                    notifyFailure(true)
                    notifyNotBuilt(false)
                    notifyBackToNormal(true)
                    notifySuccess(false)
                    notifyRepeatedFailure(false)
                    notifyUnstable(true)
                    startNotification(false)
                    includeTestSummary(false)
                    includeCustomMessage(false)
                    customMessage(null)
                    sendAs(null)
                    commitInfoChoice('NONE')
                    teamDomain(null)
                    authToken(null)
                }
                wsCleanup {
                    cleanWhenAborted(true)
                    cleanWhenNotBuilt(true)
                    cleanWhenFailure(true)
                    cleanWhenSuccess(true)
                    cleanWhenUnstable(true)
                }
            }
       }
}

然后在更新Jenkins和插件后，更改为：

Processing DSL script jobBuilder.groovy

因此，从逻辑上讲，这表明我们需要将baseUrl添加到DSL脚本中。但有人知道为什么吗？还有，有人知道为什么我们没有改变任何事情，情况却突然改变了吗

编辑

我已经在脚本中添加了以下参数（在

slackNotifier

下），这解决了这个问题；但它仍然没有回答这个问题

baseUrl(null)

---

这是Jenkins插件“Slack Notifier”v2.2中引入的一个新参数

---

Slack插件v2.4中的这一提交破坏了与作业DSL脚本的兼容性，使许多选项成为强制性的（再次）：

兼容性已在v2.11中恢复：

---

谢谢你，尽管在这之前我已经上过2.3了。问题是，它似乎在以前没有的地方变成了必需的，而这在插件没有升级的情况下就发生了。值得注意的是，将

baseUrl（null）

选项保留在中会导致作业失败，这需要删除，正如我今天早上发现的那样。

baseUrl(null)
