Keycloak のバージョン 1.8 (Demo と呼ばれるバージョン) をダウンロードしました。これには、JBoss アプリケーション サーバーで既に実行されている、簡単にテストできるいくつかのプロジェクトが含まれています。

製品をインストールし、アクセスできるようになりました。

前提条件を確認しました：

  • java -バージョン > 1.8.0_65 (1.8.* が必要)
  • mvn -version > 3.10.0 (3.2.1 が必要)
  • git --version > インストール済み

YouTube のチュートリアル (「Keycloak チュートリアル: 基本パート 2」) に従って、pom.xmlファイルが存在するディレクトリに入ると、「mvn jboss-as:deploy」を起動しますが、JBoss で次のエラーが表示されます。
