Create a simple java application and associated code scanning workflow

[mickeygousset]

Create a simple java application. It should have several packages that it uses, and at least one of the packages should throw a critical or high codeql alert.

Also create a github actions workflow file that will scan the java application using codeql. The workflow should use the autobuild functionality.

What do I need to add to the workflow, if anything to get my dependencies to show up in the dependency graph?
