AzureWebAppServicesにJenkinsPipelineを使ってMavenWebAppをデプロイ・公開したい

前提・実現したいこと

主にサーブレットとJSPで構成された、Maven Webappプロジェクトが、
GitHubプライベートリポジトリにあります。

Azure上に、ソリューションテンプレートで作成したJenkinsサーバがあり、
GitHubからリソースを取得し、パイプラインでビルド、テストを行い
最終的に、Azure Webapp Serviceにデプロイ・公開したいです。

現段階で、テストの過程はスキップし、Azure Webapp Serviceにデプロイするところを取り組んでいます。

Jenkins Pipelineのジョブ、デプロイメント・センターのログでは,
「デプロイ成功」となっているのですが、Azure Webapp ServiceのURLにアクセスしても、マイクロソフト社の ' Hey, Java developers!...' という画面しか表示されません。

試行錯誤でここまで辿り着いたので、何が原因なのか見当がつきません。

皆様のお知恵をお貸し頂けないでしょうか。
よろしくお願いいたします。
