Errors when compiling Project

I set up a development server following the example in the SDK. I'm having an issue when I compile - it looks like it's trying to download packages from inductive but I get a not authorized error. I'm sure I followed all the steps correctly. Is there some kind of certificate I need to install?

No, there shouldn't be.

How about you share something more useful like error messages?

Certainly. This is what I get (Windows 10):

Starting a Gradle Daemon (subsequent builds will be faster)
Required keystore file location not found. Specify via flag '--keystoreFile=', or in gradle.properties file as 'ignition.signing.keystoreFile='
Required certificate file location not found. Specify via flag '--certFile=', or in gradle.properties file as 'ignition.signing.certFile='
