Building jar through the open source

Hi,

I have made some modifications to the open-source routing engine.

When I launch the open source via Intellij I can make route requests using the CMD but I can no longer open the browser localhost:8989 to access the visual map using my Intellij ran code/server.

On top of that, I am rebuilding the open source back into a Jar but im unable to run through CMD, due to an issue with the certificate signature, and upon a second rebuild it is no longer finding the GraphHopperApplication main.

I would really appreciate some help to resolve this.

Thanks,
Brandon
