搭建Neovim Java开发环境时mvnw clean install执行报错求助

我正尝试搭建Neovim的Java开发环境，作为新手自行尝试失败后跟着教程操作。先克隆了microsoft/java-debug仓库，执行mvnw clean install时报错：

当前处于公网环境，请问该报错是否有可能是防火墙导致的？

• 这个报错不是防火墙导致的，核心原因是Java版本不兼容：
  报错日志里明确指出，org/eclipse/tycho/core/p2/P2ArtifactRepositoryLayout类文件是用Java 11（对应class file version 55.0）编译的，但你当前使用的JDK版本仅支持最高Java 8（class file version 52.0），无法加载高版本编译的类文件。
• 解决方法：
  1. 安装Java 11或更高版本的JDK
  2. 验证当前终端的JDK版本：执行java -version，确认输出为11及以上
  3. 若版本不符，通过设置JAVA_HOME环境变量切换到高版本JDK
  4. 重新执行mvnw clean install
