Jenkinsfile - groovy readFile方法導致序列化錯誤

我想加載內容從文件到變量在groovy。Jenkinsfile - groovy readFile方法導致序列化錯誤

這是我Jenkinsfile的一部分：

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

我得到了一個錯誤：

    in field caller 
    in field e

我的文件是一個多。我如何讀取這些文件的內容並將其存儲到變量中？我試過運行sh'cat file'並存儲輸出，但是我得到了同樣的錯誤。當我嘗試讀取其他文件時，我總是得到相同的序列化異常。

這是我Jenkinsfile：

#!/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' 
    } 
}

如上所述，您需要發佈更多的'Jenkinsfile'，因爲您可能會丟失無法序列化的變量。 – mkobit

@mkobit：我添加了我的Jenkinsfile – esio

我真的不清楚java.util.regex.Matcher是從哪裏來的。 'java.util.regex.Matcher'不是可序列化的，所以如果你有那種類型的話，這個異常是有意義的。雖然我沒有看到它來自哪裏:(。 – mkobit

我固定的問題BU它可能是一個骯髒的解決辦法，我不知道。 :)

解決方案：創建@NonCPS功能，讀取文件，並返回內容：

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

但是函數調用必須在舞臺之上，而不是再次出現序列化的問題，我不知道爲什麼。 ..
