I'd like to generate dashboard report...
jmeter -g [QA]xxxxxxx201801291450365319.jtl -o [QA]xxxxxx201801291450365319
But I got error message : An error occurred: Data exporter "html" is unable to export data


Step 1. Open jmeter.log ( it is under Jmeter\bin folder) and check.... I got the root cause: my report-template folder is missing.

Step 2. Download JMeter again and copy report-template from
Step 3. Paste to Jmeter\bin folder

Step 3. Re-generate dashboard...,  it works.
