jMeter java.lang.IllegalArgumentException: File example.csv must exist and be readable

问题

I updated jMeter 2.9 to 3.2 and having issues with old test cases. When I open .jmx file with jMeter 2.9 all tests runs smoothly, but when using version 3.2 from same location I get a message: The file jmeter-results.xml already exists, what do you want to do? Append to existing file - Don't start - Overwrite existing file. Doesn't matter what I choose, it doesn't work.

Log file:

1. If you are talking about this warning:

   it is enhancement introduced in JMeter 3.2 within the bounds of issue 58164. Just remove all the listeners from your Test Plan and the warning will go away. Actually you don't need to have any listeners as they create overhead and may ruin your test, consider storing your test result to .jtl result file using -l command-line argument instead.

2. Looking into this line:

   2017-07-30 14:29:57,918 INFO o.a.j.s.FileServer: Stored: testdata/test.csv

   you simply forgot to copy your test.csv file to new JMeter installation

   • Go to the JMeter 3.2 "bin" folder
   • Create folder testdata there
   • Copy your test.csv file into the testdata folder

   Or just use the absolute path to your test.csv file.

Workaround:

Place the .csv file in the path were you have your scripts and change the fully qualified CSV path with just .csv filename.
