Maven kursen uppdaterad

Maven har i grunden revolutionerat Java världen, med dess införande av standardisering av projekt via konfigurering-via-konventioner, automagisk beroendehantering, generering av en komplett webbplats för teknisk projekt dokumentation med mera.

Denna kurs vänder sig till dig som ska börja i ett Java projekt där man använder Maven som projekt-byggnads-ramverk och snabbt vill komma igång och vara produktiv. Kursen utgår från Maven version 3 och använder moderna versioner av Java och andra verktyg.
