It gives me an error - File Scan Error, Only YML rule sets or ZIP source files can be uploaded, while uploading webapp source code , I am trying with sample JavaEE7-eclipse-master.zip file attached

Kindly provide me a sample source code that I can use to scan and generate a few reports

I was able to scan this code with the latest ephemerol source and default rule base. Did you upload a custom rule base for this zip file?
