vijayana The issue is, First you need to create a Plug in Project. once the project is created, then you need to select the created project (but not the src), click on File > New > Other > Appian Expression Function, so that it will created. 
 
You cannot create an Appian Expression Function without creating the plug in project, and as per my understanding you might have tried creating Appian Expression Function without creating plug in project. 
 
I hope this will solve your issue.
