Hi,

Command on CLI:
"java -jar jplag-4.3.0-jar-with-dependencies.jar -l cpp -s /home/hemachand/Downloads/VDA-1/PA3_Plag/PA3_Plag_cpp/ -r Res_cpp"

I need to use it urgently can you please help me resolve the issues.
PA3_Plag_cpp has folder with the name of each student and each of these folders have .cpp and .h files.

I'm using Linux OS.

So, your legacy version is working for c++ files but I think your latest version has some issue with the cpp files. It is unable to read the root directory.

Try running:
java -jar jplag-4.3.0-jar-with-dependencies.jar -l cpp -r Res_cpp /home/hemachand/Downloads/VDA-1/PA3_Plag/PA3_Plag_cpp/

or navigate to the folder (with cd) and run:
java -jar jplag-4.3.0-jar-with-dependencies.jar -l cpp -r Res_cpp ./PA3_Plag_cpp/

Also, feel free to test the cpp2 language module and see if it works better for you.
