jmx和csv文件在同一路径下，相对路径读取文件内容失败
错误信息：
java.lang.IllegalArgumentException: Could not read file header line for file userInfo.csv

Hello @rollno748 - The JMeter script which has the extended csv data set to any request in the script, does not open in JMeter and shows a dialog to install the plug-in first. Up on installing the plug-in "extended-csv-dataset-config-2.0" and restarting JMeter, it still does not open the script and shows the same message to install the plugin.

I am assuming JMeter is not detecting the installed plug-in "extended-csv-dataset-config-2.0" (still shows in available plug-ins tab of plug-in manager after installation too).

Note: I removed the jar file 2.0 from ext folder of lib directory and replaced with version 1.1 (di-extended-csv-1.1.jar) and it works fine.
So the problem is with version 2.0

I was playing around with this today as I'm learning JMeter (but very familiar with LoadRunner) and glad to see something designed to handle the data like LR does, however I am encountering what appears to be a bug.

I setup a thread group with 3 threads and a loop count of 3. Initially I purposefully provided too few rows of data into the data file and wanted to see what it looked like when I altered the 'when out of values' but I noticed something strange, that my last row of data was not being reused, instead the 2nd last row was there twice.

So I updated the file to have exactly the number of rows needed (9 due to the 3x3) and tried again and still got the 2nd last row being reused. I did recall LR having an issue at one time if the data file didn't have a blank line, so tried with and without and still seeing same behavior. I ended up having to put 2 blank lines in my files end to get it to work. So there is a workaround I suppose, but in my mind It's a bug because I was using Unique and it reused a value. I varied the When out of values, and with abort thread i still got 2nd last row twice. I changed it to Continue cyclic and it was same, so based on this it doesn't seem to believe it's out of data (it's not).

For this example I'm just using a Java Request with the name - Java Request_${user}${password}${__threadNum}

And my CSV looks like:
user,password
jojo1,bean
jojo2,bean
jojo3,bean
jojo4,bean
jojo5,bean
jojo6,bean
jojo7,bean
jojo8,bean
jojo9,bean
{this is a blank row - just putting the text here for clarification)

My config for the step is here

And the result here shows thread 3 using jojo8 twice and never used jojo9.

If I left all other settings the same, but put 2 blank rows, then it worked correctly -> but 2 blank rows is really weird. Also to note, the behavior is same with 0 or 1 blank row at bottom of file.

Most likely issue with this line

If I turn off quoted data, lines are random again

Feature to view the csv using the default text editor (Windows/Mac/Linux)

Below is the error.

(Thanks for creating and supporting this plugin!)

How to replicate: run jmeter in distributed mode

• command to run on the worker: bin/jmeter-server -Dserver.rmi.localport=50000 -Dserver_port=1099

The error message

• this error message was only visible in 5.6.3 (5.6.2 did not properly display the error)

source code

• looking at the source code I can see a check for isNonGUI

  • Extended-csv-dataset-config/src/main/java/com/di/jmeter/config/ExtendedCsvDataSetConfig.java

    Line 206 in 0f840d0

    if(JMeter.isNonGUI()){

• looking at the jmeter source code for that function (in v5.1.1 as configured in this plugin's POM.xml

    public static boolean isNonGUI() {
      return "true".equals(System.getProperty("JMeter.NonGui"));
   }

• doing a check on the property value with a JSR223 sampler we see that JMeter.NonGui: null
  • hence the NullPointerException error with the plug in

log.info("JMeter.NonGui: {}", System.getProperty("JMeter.NonGui"))

2024-03-05 23:23:16,510 INFO o.a.j.p.j.s.J.JSR223 Sampler: JMeter.NonGui: null

New GUI element to disable subsequent options appropriately without referring the table

The other combinations are working fine except for this one, I am not sure if I am doing anything wrong.
When I was trying to select the unique row on each iteration/once the jmeter is throwing below error:

Thanks for developing this plugin. Do you have any plan to upload the jar file to any mvn repository?
