我刚刚下载了 Keycloak 的 1.8 版（名为 Demo 的版本），其中包含一些已经在 J​​Boss 应用程序服务器上完成的项目，这些项目应该很容易测试。

我安装了该产品，并且可以访问它。

我检查了先决条件：

  • java -version > 1.8.0_65 (需要1.8.*)
  • mvn -version > 3.10.0（需要 3.2.1）
  • git --version > 已安装

只需按照 YouTube 中的教程（“Keycloak 教程：基础知识第 2 部分”），当我进入文件所在的目录时pom.xml，我启动“mvn jboss-as:deploy”，但 JBoss 向我显示此错误：

我应该如何解决这个错误？
