Question

我正在尝试在groovy中将内容从文件加载到变量。

这是我Jenkinsfile的一部分：

def x = readFile("${WORKSPACE}/config/CONFIGURATION_FILE")
println x

我收到了一个错误：

an exception which occurred:
    in field locals
    in field caller
    in field e
    in field program

我的文件是多行的。如何读取这些文件的内容并将其存储到变量中？我试过运行sh'cat文件'并存储输出，但我得到了同样的错误。当我尝试阅读其他文件时，我总是得到相同的序列化异常。

这是我的Jenkins文件：

#!/usr/bin/env groovy
import hudson.model.*
import hudson.plugins.jira.*

def PARAMS = ''

node('build') {
    stage('Clean workspace') {
        deleteDir()
    }
    stage('Download sources') {
      git url: 'ssh://my_repo.git'
      sh 'git submodule update --init --recursive'
    }
    stage('Set variables') {           
        def x = "${WORKSPACE}/file"
        PARAMS = readFile(x)
    }
    stage('Deploy') {
      sh 'ansible-playbook -u user -e "params="' + PARAMS + ' deploy.yml'
    }
}

我解决了这个问题，这可能是一个肮脏的解决方法，我不知道。：）

解决方案：创建@NonCPS函数，读取文件并返回内容：

@NonCPS
def get_params(){
    def file = "${WORKSPACE}/file"
    def content = readFile(file)
    return content
}
stage('Set variables') {           
    PARAMS = get_params()
}

但是函数调用必须在阶段之上，而是再次发生序列化问题，我不知道为什么......

Jenkinsfile - groovy readFile方法导致序列化错误
