My friend ha just big exam in their programming class. They got the assignment week before and were allowed to use libraries. They were using Java and Maven repos. He created his own Maven repo and added finished assignment as a library. He just added his repo to the gradle project and selected his library as a dependecy. He then created one class with main method, 10 lines of user input and called main method from his library. Since the school newly tests students work automatically, he instantly passed with 100% and had to look like hes actually working for next 3 hours 😂. Noone noticed anything after 2 weeks 😂
