詹金斯拋出序列化異常

Question

我在Jenkins管道的第一行“ writeFile”下遇到異常，在這里我使用成功的SimpleTemplateEngine更新模板，此后，我運行bat命令移動一些文件。 發生異常后，我發布了部分代碼，這些代碼已被詹金斯（Jenkins）淘汰。

[Pipeline] writeFile

[Pipeline] // stage

Answer 1

如果不顯示整個管道，則很難確切地說出發生的位置。 Jenkins可以暫停管道，並要求任何狀態（包括局部變量和其他內容）都必須是Serializable 。 詹金斯流水線背后的CPS引擎出於很多原因要求這樣做，例如在代理程序/主服務器斷開連接的情況下選擇流水線。 某些管道代碼可以包裝在@NonCPS ，而不由CPS引擎進行轉換。

准確檢測發生位置的一種方法是在不同位置添加一個sleep步驟（例如sleep(time: 1, unit: 'MILLISECONDS') ，然后逐漸將其逐步移動以檢測哪一行代碼導致序列化問題（如果stacktrace不會將您指向正確的位置。

您的示例中最明顯的對象是def engine=new groovy.text.SimpleTemplateEngine() ，因為groovy.text.SimpleTemplateEngine()不可Serializable 。

Answer 2

如@mkobit所說， groovy.text.SimpleTemplateEngine 不可序列化。 對我來說，簡單地切換到groovy.text.StreamingTemplateEngine可以避免序列化問題並提供所需的功能。

FWIW-我在Groovy文檔中發現了此選項： http : //docs.groovy-lang.org/docs/next/html/documentation/template-engines.html#_template_framework然后嘗試使用StreamingTemplateEngine 。 這些文檔中列出的其他一些引擎也可能會工作-但在找到適合我需求的引擎后，我沒有嘗試過。 如果您最終確定其他任何人都可以工作，則請添加評論。

作為參考，這是我用來驗證的管道腳本：

node {
    stage('template') {
        def raw      = 'b:"${b}"'
        def dict     = [:]
        def engine   = new groovy.text.StreamingTemplateEngine()
        def template = engine.createTemplate(raw).make(dict)

        dict.b = 'BBB'
        echo template.toString()

        dict.b = 'bbb'
        echo template.toString()
    }
}

這是生成的輸出（隱藏了一些“個人”值）：

[Pipeline] node
Running on JENKINS-AGENT in /opt/jenkins-slave/workspace/JOB-PATH/zz-test@2
[Pipeline] {
[Pipeline] stage
[Pipeline] { (template)

[Pipeline] echo

[Pipeline] }
[Pipeline] // stage
[Pipeline] }
[Pipeline] // node
[Pipeline] End of Pipeline
