java.io.NotSerializableException：groovy.text.StreamingTemplateEngine

我在jenkins中创建了管道作业，首先使用StreamingTemplateEngine对象创建Template变量并使用它，然后调用sh step。

这是代码：

node('node') {

    stage ("Creating Template and run sh command") {
        def text = 'Dear "$firstname $lastname",\nSo nice to meet you in <% print city %>.\nSee you in ${month},\n${signed}'
        def binding = ["firstname":"Sam", "lastname":"Pullara", "city":"San Francisco", "month":"December", "signed":"Groovy-Dev"]
        def engine = new groovy.text.StreamingTemplateEngine()
        def template = engine.createTemplate(text).make(binding)
        def result = 'Dear "Sam Pullara",\nSo nice to meet you in San Francisco.\nSee you in December,\nGroovy-Dev'
        print result
        sh ("echo Hello World")
    }
}

当我运行管道时，我收到以下错误：

我查看了有关Not Serializable问题的其他答案，这些问题建议将Not Serializable对象置于函数内并使用@NonCPS注释该函数，但我仍然得到相同的错误。

这是带@NonCPS注释的代码：

node('node') {

    stage ("Creating Template") {
        def text = 'Dear "$firstname $lastname",\nSo nice to meet you in <% print city %>.\nSee you in ${month},\n${signed}'
        def binding = ["firstname":"Sam", "lastname":"Pullara", "city":"San Francisco", "month":"December", "signed":"Groovy-Dev"]
        def engine = MakeTemplate()
        def template = engine.createTemplate(text).make(binding)
        def result = 'Dear "Sam Pullara",\nSo nice to meet you in San Francisco.\nSee you in December,\nGroovy-Dev'
        print result
    }

    stage ("Run sh command") {
        sh ("echo Hello World")
    }
}

@NonCPS
def MakeTemplate() {
    def Template = new groovy.text.StreamingTemplateEngine()
    return Template
}

当我将Template变量和sh步骤分成两个阶段时，作业运行没有任何问题。

这是我将Template变量和sh步骤分成两个不同阶段时的代码：

node('node') {

    stage ("Creating Template") {
        def text = 'Dear "$firstname $lastname",\nSo nice to meet you in <% print city %>.\nSee you in ${month},\n${signed}'
        def binding = ["firstname":"Sam", "lastname":"Pullara", "city":"San Francisco", "month":"December", "signed":"Groovy-Dev"]
        def engine = new groovy.text.StreamingTemplateEngine()
        def template = engine.createTemplate(text).make(binding)
        def result = 'Dear "Sam Pullara",\nSo nice to meet you in San Francisco.\nSee you in December,\nGroovy-Dev'
        print result
    }

    stage ("Run sh command") {
        sh ("echo Hello World")
    }
}

有人建议我能做些什么吗？ 谢谢！

处理使用非Serializable类的自定义逻辑的最简单方法是将它们移动到@NonCPS带注释的方法。

@NonCps
String doTemplate() {
    def text = 'Dear "$firstname $lastname",\nSo nice to meet you in <% print city %>.\nSee you in ${month},\n${signed}'
    def binding = ["firstname":"Sam", "lastname":"Pullara", "city":"San Francisco", "month":"December", "signed":"Groovy-Dev"]
    def engine = new groovy.text.StreamingTemplateEngine()
    def template = engine.createTemplate(text).make(binding)
    def result = 'Dear "Sam Pullara",\nSo nice to meet you in San Francisco.\nSee you in December,\nGroovy-Dev'
    return result
}
