我正在尝试运行 vaadin-charts-demo。
与此类似的问题： Maven 无法解析依赖项，无法解析工件

尝试谷歌搜索 vaadin-chart-examples 和 chart-demos maven、repository 等，但没有找到解决方案。如何解决？
[[编辑]] 项目从这里导入： https ://github.com/vaadin/charts/tree/7a55e8dab5b9941a05603c2624a576866e86045d
按照这些说明： https ://github.com/vaadin/charts/blob/7a55e8dab5b9941a05603c2624a576866e86045d/DevInstructions.md
安装后，无法编译小部件
这些说明是针对 Luna 的，我正在使用 Mars，不知道这会如何影响事物。
