java - Apache Karaf (4.2.6)外壳: Unable to install webconsole

Question

我正在尝试执行一项功能:在 Karaf 版本 4.2.6 中安装 Webconsole，但在我尝试设置 Karaf 的每台计算机上，我都会收到此错误消息:

Error executing command: Error:
        Error downloading mvn:org.apache.karaf.webconsole/org.apache.karaf.webconsole.instance/4.2.6

无论是 Windows 还是 Linux Mint，我都无法安装 Webconsole。我已经卸载并重新安装了 Java 1.8.0_241 和 Maven 3.6.3，并在两个操作系统上设置了各自的环境变量。

我错过了什么吗？

这是完整的控制台日志:

修改 org.ops4j.pax.url.mvn.cfg 配置文件中的 org.ops4j.pax.url.mvn.repositories 属性以改用 https http的。自 2020 年 1 月 15 日起，Maven 中心禁用 http
