Créer un fichier avec du contenu en utilisant Groovy dans le pipeline Jenkins
J'essaie de créer un fichier appelé groovy1.txt avec le contenu "Travailler avec des fichiers à la manière de Groovy est facile."
Remarque: je ne souhaite pas utiliser le shell pour créer ce fichier, je souhaite plutôt utiliser Groovy pour y parvenir.
J'ai le script suivant dans mon pipeline Jenkins.
node {
def file1 = new File('groovy1.txt')
file1.write 'Working with files the Groovy way is easy.\n'
sh 'ls -l'
// Expecting the file groovy1.txt should present with the content mentioned above
}
Mais il génère une erreur FileNotFound (autorisation refusée) comme ci-dessous

Le pipeline Jenkins fournit une étape writeFile qui peut être utilisée pour écrire un fichier dans l'espace de travail du travail.
Regardez l'exemple suivant:
node {
writeFile file: 'groovy1.txt', text: 'Working with files the Groovy way is easy.'
sh 'ls -l groovy1.txt'
sh 'cat groovy1.txt'
}
L'exécution de ces scripts de pipeline génère la sortie suivante:
[Pipeline] node
Running on Jenkins in /var/jenkins_home/workspace/test-pipeline
[Pipeline] {
[Pipeline] writeFile
[Pipeline] sh
[test-pipeline] Running Shell script
+ ls -l groovy1.txt
-rw-r--r-- 1 jenkins jenkins 42 Jul 8 16:38 groovy1.txt
[Pipeline] sh
[test-pipeline] Running Shell script
+ cat groovy1.txt
Working with files the Groovy way is easy.[Pipeline] }
[Pipeline] // node
[Pipeline] End of Pipeline
Finished: SUCCESS
Utilisation de Java
FileComme Jon S mentionné dans le commentaire, Java
new File("${env.WORKSPACE}/groovy1.txt")) fonctionnera uniquement si votre étape de noeud est exécutée sur un noeud maître - si elle est exécutée sur un noeud esclave, le code de votre pipeline échouera. Vous pouvez vérifier le thread de débordement de pile suivant pour plus d'informations:
