Microsoftのドキュメント「Java と Maven を使用して初めての関数を作成する (プレビュー)」を以下の環境で試しました。
- 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 (自分の環境ではプリインストール）
- npm 5.6.0（自分の環境ではプリインストール）
無事に動いたので以下メモ。
Azure Functions Core Toolsのインストール
ドキュメントを参考にAzure Functions Core Toolsをインストールしました。手順通り、まずは.NET Coreをインストールしました。
.NET Coreのダウンロードページで.NET Core SDKをダウンロード
インストールを進めます。
インストール完了です。
npmでAzure Functions Core Toolsをインストールします。自分の環境は既にインストール済だったnpm 5.6.0を利用しました。
npm install -g azure-functions-core-tools@core
azure-functions-archetypeで雛形を作成
Mavenの「azure-functions-archetype」を使って雛形を作成します。
VSCodeで「表示」->「コマンドパレット」から「Maven:Generate from Maven Archetype」を選択して、保存先のフォルダを選択します。
「azure-functions-archetype」を選択します。
すると自動的に以下の処理が開始されます。
PS D:\web\azure\AzureFunctionsJava> cmd /c mvn archetype:generate -DarchetypeArtifactId="azure-functions-archetype" -DarchetypeGroupId="com.microsoft.azure"

これで雛形の完成です。雛形といいつつ、以下のようなコードが書かれているので、そのまま動かせます。
package tech.kikutaro;

@FunctionName("HttpTrigger-Java")
public HttpResponseMessage run(

} else {

}
}
}
