I have a Spring Boot with devtools project, and I got the following error when I tried to run it:


***************************
APPLICATION FAILED TO START
***************************

Description:

Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.

Reason: Failed to determine a suitable driver class


I suspect the main reason for this is that I don't even have an application.properties file in the src/main/resources folder. I tried to right-click-new, but nothing pops up that gives me the option to create a .properties file manually. Do I need to configure a build path to get this file created? If so, how do I do that once I'm in the Java Build Path menu?
