Échec de la création du pipeline en raison d’une erreur Python non disponible

Correction de l’échec de Pipeline Build en raison d’une erreur Python en créant un projet Maven qui utilise le module externe exec pour installer Python3.

Description description

Environnement

AEM as a Cloud Service

Problème/Symptômes

La version 3.10 de Python doit être installée, car le code frontal nécessite que Python crée l’application.

Cependant, lors du déploiement du pipeline dans Cloud Manager, la version échoue avec l’erreur suivante :

Résolution resolution

Si Python n'est pas installé, Maven peut être installé en suivant ces étapes.

Pour créer un projet Maven qui utilise le module externe exec pour installer Python3, une configuration du fichier pom.xml doit être effectuée.

Exemple :

<project xmlns="http://maven.apache.org/POM/4.0.0"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"><modelVersion>4.0.0</modelVersion><groupId>com.example</groupId><artifactId>PythonInstaller</artifactId><version>1.0-SNAPSHOT</version><packaging>jar</packaging>
<build><plugins><plugin><groupId>org.codehaus.mojo</groupId><artifactId>exec-maven-plugin</artifactId><version>1.6.0</version><executions><execution><id>apt-get-update</id><phase>validate</phase><goals><goal>exec</goal></goals><configuration><executable>apt-get</executable><arguments><argument>update</argument></arguments></configuration></execution><execution><id>install-python3</id><phase>validate</phase><goals><goal>exec</goal></goals><configuration><executable>apt-get</executable><arguments><argument>install</argument><argument>-y</argument><argument>python3</argument></arguments></configuration></execution></executions></plugin></plugins></build></project>

La configuration Maven exécute la mise à jour apt-get et les commandes apt-get install -y python3 pendant la phase de validation du cycle de vie de la version Maven. Notez également que cela ne fonctionne que si la version est exécutée dans un environnement où la commande apt-get est disponible et en cours d’exécution. La version doit disposer des autorisations suffisantes pour installer les packages.

De même, si vous devez installer Python 3.11, le fichier pom.xml doit se présenter comme suit :

**``` <project xmlns="http://maven.apache.org/POM/4.0.0"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> 4.0.0 com.example PythonInstaller 1.0-SNAPSHOT jar

<build><plugins><plugin><groupId>org.codehaus.mojo</groupId><artifactId>exec-maven-plugin</artifactId><version>1.6.0</version><executions><execution><id>apt-get-update</id><phase>validate</phase><goals><goal>exec</goal></goals><configuration><executable>apt-get</executable><arguments><argument>update</argument></arguments></configuration></execution><execution><id>install-python3.11</id><phase>validate</phase><goals><goal>exec</goal></goals><configuration><executable>apt-get</executable><arguments><argument>install</argument><argument>-y</argument><argument>python3.11</argument></arguments></configuration></execution></executions></plugin></plugins></build></project>
```**
