Hello everyone, I have managed to get my VM up and running. A big thank you to Isaac, Yannick and Victor for the constant support.
I am now incorporating the notification service into the demo-server however, I keep getting this error. https://pastebin.com/LW6CUwJ3 NB: I have made a build of the notification microservice and publishToMavenLocal. I have also added the dependency to the build.gradle file in the demo server. I believe this issue has to do with locating the notification artefacts in the .m2. *Best Regards,* *Ebenezer Graham* *BSc (Hons) Computing* [image: EmailSignature.png] Beau Plan Business Park | West Building Pamplemousses | Mauritius <http://www.pactmart.com/> <http://www.pactmart.com/> www.pactmart.com | Freelancing made easy.
