错误消息表明程序需要 Java 11：，Require-Capability: osgi.ee; filter:="(&(osgi.ee=JavaSE)(version=11))但您的问题表明您当前正在使用 Java 8。要在 Ubuntu 18.04 及更高版本中安装 Java 11，请打开终端并输入：

sudo apt install openjdk-11-jdk

您可以同时安装多个 Java 版本，并使用 设置默认 Java 版本update-java-alternatives。

$更新 Java 替代方案
用法：update-java-alternatives [--jre-headless] [--jre] [--plugin] [-v|--verbose]
