Resolving NED Path issue Veins/Omnet++ - simulation

Question

I am working with veins. I needed to change the default behavior of BaseWaveApplLayer. Rather doing in file changes, I created a second application file with the name MyApp. I added MyApp.cc, MyApp.h, MyApp.ned files. Then I duplicated TraCIDemoRSU11p, and added files for TraCIDemoRSU11pEnhanced. Now in .ini file when I changed *.rsu[*].applType to point to "TraCIDemoRSU11pEnhanced". It compiles fine, but when I try to run it, generates the following error:
Submodule appl: no module type named `TraCIDemo11pEnhanced' found that implements module interface org.car2x.veins.base.modules.IBaseApplLayer (not in the loaded NED files?).
In MyApp.ned file it is declared to be of type IBaseApplLayer. I tried setting ned-path parameter in ini file, didn't resolve the problem. In veins project properties, NED source folder is checked. Do I have to add the ned path for the newly created application file, somewhere?

Try using the cookiecutter package (https://veins.car2x.org/tutorial/#newprojects) to create new applications that use veins instead of copying and pasting files:
Use pip to install the package (https://github.com/cookiecutter/cookiecutter)
Then follow the steps in (https://github.com/veins/cookiecutter-veins-project/blob/master/README.md) to create the new project; following the prompts that appear.
This will create a new project that uses Veins and has the application layer-related files for you to update according to your application with no errors.
