Jenkinsfile - groovy readFileメソッドでシリアル化エラーが発生する

Question

Groovyでファイルから変数に内容をロードしようとしています。

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

が、私はエラーを得た：

    in field e 
    in field program

私のファイルが複数行である

は、これは私のJenkinsfileの一部です。これらのファイルの内容を読み込み、変数に格納するにはどうすればよいですか？私はsh 'catファイル'とストア出力を実行しようとしましたが、同じエラーが発生しました。他のファイルを読み込もうとすると、常に同じシリアライゼーション例外が発生します。

これは私のJenkinsfileです：

#!/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' 
    } 
} 

Answer 1

私はその問題を修正BUそれが汚れてこの問題を回避することができ、私は知りません。 :)

ソリューション： 、@NonCPS関数を作成したファイルを読み、内容を返す：

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

しかし、関数呼び出しではなく、シリアル化の問題が再び発生し、私はなぜ知らない、舞台の上でなければなりません。 ..
