java - 创建新的 XSSFWorkbook .xlsx 文件时出错？

Question

我正在尝试运行 Apache Poi 提供的 BarChart 示例，以使用示例类创建 XSSFWorkbook。

我的 maven 版本中有 poi-ooxml 版本 4.1.0，并且使用 Eclipse 作为我的 IDE。

我读过一些帖子，但大多数都与关闭工作簿和关闭输出流的顺序有关，但这不是我的问题。它在实际的 workbook.write() 命令上失败。我似乎无法弄清楚为什么会这样？

我还阅读了一些关于缺少 jar 文件的内容，但我使用的是 maven 依赖项，所以我不知道这是怎么发生的。

任何帮助，将不胜感激。
