Because of Oracle commercial copyright issues, MAVEN cannot download jar packages directly through the central repository, and if you want to use jar packs, you need to manually process them. Step One: Place the Ojdbc14.jar in the user's directory, such as: C:\Users\qicyt1812 Step Two: Execute the command in cmd: mvn install:install-file-dgroupid=com.oracle-dartifactid=ojdbc14-dversion=10.2.0.1.0- Dpackaging=jar-dfile=ojdbc14.jar C:\USERS
