I had some issues with downloading the various software, but using homebrew for both maven and postgres worked wonderfully
For java, maven and git I checked my version in the terminal to confirm that I did indeed have it downloaded.
I also had some issues with the version control and pushing
to git. I did not have an SSH key in github, but as soon
as I made that I could push my own repository. I also had some
issues pushing my the java-getting-started. I did manage to do
it by adding the ssh key in the terminal in intellij, but I
wanted to push the project to my own github, and that I could
not manage to do.
I do not really understand where I am pushing to when I pushed the java-getting-started repository, if not my own.
