JMeter CLI 报告生成失败 - org.apache.jmeter.report.dashboard.GenerationException：数据导出器 "json"
JMeter CLI report generation fails - org.apache.jmeter.report.dashboard.GenerationException: Data exporter "json"

我使用 CLI 如下：

最后，你可以看到我们有：

请注意，报告的扩展名是 CSV 还是 JTL 并不重要。
我 是 能够生成 JTL 报告，然后 运行 jmeter -g <my JTL file>，但我想要 -e 选项工作。
更新：现在 g 选项出现错误：

所以这一切都开始于：
Caused by: java.io.IOException: Unable to create directory C:\Users\guyl\OneDrive - xxx LTD\Guy\JMeter\output082020"
如果该文件夹不存在，应该创建它，不是吗？
JMeter 将仅创建 1 级文件夹，而不是完整的层次结构。
其次，尽量避免使用包含空格的文件夹。
我也遇到了这个错误，我的问题的解决方案是通过这个命令：
jmeter -n -t “测试文件的位置” -l “结果文件的位置” -e -o “报告文件夹的位置”
第三个选项“报告文件夹的位置”需要是一个全新的不存在的文件夹。告诉命令创建文件夹后，我的 HTML 报告成功了！
我刚刚遇到同样的错误消息，使用 jMeter 5.4.1。
就我而言，我最终使用 ProcMon
调查了问题
Procmon 显示文件夹路径中包含右双引号 "，这是 windows folder/file 名称中的无效字符。
我很幸运，我的路径中没有任何空格，所以删除双引号对我没有影响。尝试使用名称中没有空格的文件夹，或者在路径中使用 8.3 short names。
