Jmeter: Test plan which was working in windows failing in Centos - jmeter

Question

I have a test plan which has two threads.
Each thread takes two CSV files as test data.
I have provided the CSV path as \testdata\csvtest1.csv this directory is located at src\test\jmeter\testdata, when I run this plan it works in Windows both in GUI mode and in non-gui mode via maven mvn clean verify.
But when I run this in Centos 7, it is giving below error I found in logs.
2018-10-04 13:56:24,739 INFO o.a.j.s.FileServer: Stored: \testdata\csvtest1.csv
2018-10-04 13:56:24,743 INFO o.a.j.s.FileServer: Stored: \testdata\csvtest2.csv
2018-10-04 13:56:24,740 ERROR o.a.j.t.JMeterThread: Test failed!
java.lang.IllegalArgumentException: File \testdata\csvtest2.csv must exist and be readable
So I manually copy-pasted test data directory with both CSV files inside Jmeter's bin directory. Still, it is giving the same error.
I have also tried solution here jMeter java.lang.IllegalArgumentException: File example.csv must exist and be readable and commented on answer but it didnt work.
Am I doing something wrong?

Answer 1

Have you tried to read documentation?
Reference JMX files and CSV data
Once you have created your JMeter tests, you'll need to copy them to <Project Dir>/src/test/jmeter. By default this plugin will pick up all the .jmx files in that directory, to specify which tests should be run please see the project documentation.
You can also put data files in this folder and reference them in your plan.
So:
Copy your csvtest1.csv, csvtest2.csv, etc to the same location where your .jmx test(s) live, to wit src/test/jmeter folder
Reference them in the CSV Data Set Config elements just by name, i.e. csvtest1.csv
See Five Ways To Launch a JMeter Test without Using the JMeter GUI article for more information on various approaches to running JMeter tests, including using JMeter Maven Plugin.

Answer 2

Try to use / (slash) as file separator and make sure the files are readable from the user executing the test plan.
