Gantt Manager is a project for the Software Development course at the university I study in collaboration with ItzUbixD.
Import the project into Eclipse IDE navigate to src/main/java/app/gui there you will find the AppStarter.java file which is the main class.
When the program start press file > load TSV. From the open file dialog find a tsv file (There are some in src/main/resources/input). After that you can enter some filters by pressing "Filters" menu and pick an option from there. Finally, you can save the gantt diagram as html, txt or md format by pressing on "Report" menu and pick an option from there.
