W ko\u0144cu pora na kodowanie!<\/p>\n
Po kilku wpisach teoretycznych na temat mojej aplikacji przysz\u0142a pora, \u017ceby napisa\u0107 pierwsze linijki w Kotlinie! Postaram si\u0119 od razu przygotowa\u0107 projekt tak, aby m\u00f3g\u0142 by\u0107 dalej rozwijany i ostatecznie sta\u0107 si\u0119 gotow\u0105 aplikacj\u0105.<\/p>\n
Aplikacja b\u0119dzie si\u0119 nazywa\u0107 plag-detector. B\u0119dzie ona podzielona na kilka modu\u0142\u00f3w. W tym wpisie zaczn\u0119 od podstawowego modu\u0142u mojej aplikacji, czyli cz\u0119\u015bci programu, kt\u00f3ra b\u0119dzie odpowiedzialna za wyliczanie prawdopodobie\u0144stwa plagiatu pomi\u0119dzy dwoma kodami \u017ar\u00f3d\u0142owymi.<\/p>\n
plag-detector\r\n|--plag-algorithm<\/pre>\nBuild tool<\/h3>\n
Przed napisaniem pierwszej linijki kodu warto wybra\u0107 narz\u0119dzie automatyzuj\u0105ce budow\u0119\u00a0aplikacji. Wyb\u00f3r pad\u0142 na klasyk\u0119, czyli stary i lubiany Maven \ud83d\ude09<\/p>\n
Konfiguracji parenta, czyli plag-detector, nie b\u0119d\u0119 pokazywa\u0142. Nie ma tam nic odkrywczego \ud83d\ude42<\/p>\n
Poni\u017cej przedstawi\u0119 pom.xml modu\u0142u plag-algorithm.<\/p>\n
