I was assigned to complete a project as part of my application for a job. The company send me to install the following requirements:
- OpenJDK 1.8
- Maven 3.x
- Git 2.x
- MySQL 5.x.
I am trying to run the app from the server side (java) and it throws this exception (probably a dependency issue but i can't find it):
