Re: Null URI when testing the project

[Carleton Moore]

It looks like the database URL has a typo.  I think it should be postgres://ubuntu:ubuntu@localhost:5432/wattdepot. You need the two // to make it a URL. 

See if that fixes the problem.

Hi,

Hope you could help me out here. I am new to Java. Here is my environment. I have to lower my java version from 1.8 to 1.7, otherwise I got different error.

$ mvn -version

Could you give me some pointers?

Thank you so much!

Thanks Carleton!  

It looks like that was in the wattdepot-server.properties release file. We might want to correct that.

## WattDepot database uri. format postgres:/<db.username>:<db.password>@<database-host>:<database-port>/<database-name>

# wattdepot-server.database.url=postgres:/myuser:secret@localhost:5432/wattdepot

I'll fix it when I get back home.
