我在 Ububntu 14.04 上使用 PDI 4.4.0：

uname -a:
Linux LT0124 3.13.0-24-generic #47-Ubuntu SMP Fri May 2 23:30:00 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

当我尝试使用 Microsoft Excel Writer Step 生成 Excel 文件时，出现以下错误：

当我在 Ubuntu 12.04 和其他机器上尝试相同的工作但步骤失败时，一切都很好。我确信问题出在我的新 Ubuntu 14.04 版本上，可能与我使用的最新 Java 版本有关：

java -version java version "1.8.0_05" Java(TM) SE Runtime Environment (build 1.8.0_05-b13) Java HotSpot(TM) 64-Bit Server VM (build 25.5-b02, 混合模式)

你知道可能是什么原因吗？

这是使用 Java 8 和 Excel Writer 步骤写入 XLSX 文件的已知错误。在修复之前，您必须降级到 Java 7 或 6。

据此，您的问题可能是使用的 excel 文件版本与根据任务配置应有的不同。

正如上面 Dave 所述，除了 Java RE 版本之外，该问题还与 .xlsx 格式明确相关。

因此，如果您并不真正依赖 .xlsx 格式的任何内容，那么切换到 2007 年之前版本的 Excel 格式（即 .xls 扩展名）可能会更容易。对我来说（使用 OpenJDK RE build 1.8.0_45-internal-b14 运行 Ubuntu 15.04）它在 .xls 格式下运行良好，但在 .xlsx 上运行失败
