Documentation Microsoft ["Créez votre première fonction à l'aide de Java et Maven (aperçu)"](https://docs.microsoft.com/en-us/azure/azure-functions/functions-create-first- J'ai essayé java-maven) dans l'environnement suivant.

Windows 10 Pro 1803(64bit)
JDK 8u152
Microsoft .NET Core SDK 2.1.402
Azure CLI 2.0.45
Visual Studio Code 1.27.1
- Java Extension Pack 0.3.0
- Language Support for Java(TM) by Red Hat 0.30.0
- Maven for Java 0.10.0 --Node.js 8.9.4 (pré-installé dans mon environnement) --npm 5.6.0 (pré-installé dans mon environnement)

Puisqu'il a fonctionné en toute sécurité, le mémo suivant.

Installation des outils de base d'Azure Functions

J'ai installé Azure Functions Core Tools en faisant référence à Documentation. Conformément à la procédure, j'ai d'abord installé .NET Core.

Téléchargez le SDK .NET Core sur la page de téléchargement .NET Core (https://www.microsoft.com/net/download)

Poursuivez l'installation.

L'installation est terminée.

Installez Azure Functions Core Tools avec npm. J'ai utilisé npm 5.6.0 qui était déjà installé dans mon environnement.

npm install -g azure-functions-core-tools@core

Créer un modèle avec azure-functions-archetype

Créez un modèle à l'aide des ["azure-functions-archetypes"] de Maven (https://github.com/Microsoft/azure-maven-archetypes).

Dans VS Code, sélectionnez ** "View" ** -> ** "Command Palette" ** - ** "Maven: Generate from Maven Archetype" ** et sélectionnez le dossier de destination.

** Sélectionnez "azure-functions-archetype" **.

Ensuite, le traitement suivant démarrera automatiquement.

PS D:\web\azure\AzureFunctionsJava> cmd /c mvn archetype:generate -DarchetypeArtifactId="azure-functions-archetype" -DarchetypeGroupId="com.microsoft.azure"
