用户数据库示例中的 UaException

Question

我正在尝试运行来自 eclipse milo project 的用户数据库独立示例，但是当我运行 Client.jar 时我得到了一个 UaException。我该如何解决这个问题？

我按照指南按照说明使用 Maven 构建了客户端和服务器 jar。服务器运行很好，但是一旦我运行客户端，我就会收到 UaException。受信任的文件夹中没有 Users.db，被拒绝的文件夹中的 Users.db 没有任何条目，所以我无法在那里更改任何内容。

我运行在 Fedora 28 上使用 Java 版本 1.8 和 Maven 版本 3.5.2。

编辑：我试图包括所有日志，但似乎太多了。如果需要更多，我可以将其全部包含在 pastebin 中。

Maven 构建（不确定此处的警告是否可能是原因）：

[[1;34mINFO[m] Scanning for projects...

Client.jar 的日志（服务器抛出相同的异常，它仅在我运行客户端之后抛出，但如果需要，我也可以包括服务器输出）：

这些错误意味着您可能没有按照说明生成接受证书的密钥库and/or。

从 milo-examples 模块中的其他示例开始可能更容易。这个有点无人维护，已从下一个版本中删除。
