Maven is a tool to build and run Java projects. For this project we are using it to automate the process of installing dependencies and compiling the system.
The file named pom.xml in the main directory controls how maven builds the project on each run, and also holds dependencies. The most important fields are properties, which holds the information about JDK and execution, and dependencies, which holds information on external sources needed to compile the project.
On each run, Maven will run test cases and compile into the target directory of the project.
For Mac you can just use brew install maven.
In the pom.xml file, under properties, we can add a line like the following:
<exec.mainClass>object_detection.ObjectDetector</exec.mainClass>
What this says is that when we call mvn exec:java, we search under src/java and execute the main method of the ObjectDetector.java class file. In this way we can test out any main method that we want.
The best way to use this in Intellij is by creating a build configuration using the following steps:
- In the top right, find the dropdown of the
Runoptions. (this should be the left of the play button and the debug button) - Press
Edit Configurations... - Press
Add new configuration - Find the maven icon and create this build config.
- Give the config a name, and then under
Run, addclean compile exec:java, which does each command in succession.

- when creating a new branch, go into the Issues tab, click on the Issue you are working on, and create a branch off of that issue
- only change things in that branch, and then when finished we can all push into master
- within the group8 directory, create a subdirectory like:
- group8/gui
- group8/database
- etc
- do your work within these subdirectories so we don't have issues resolving changes at the end
Install dependencies
mvn clean install -DskipTests
Run program
mvn exec:java
