title: Issue with ojdbc jar in Maven
body: <p>I've developed a project in Java 8 and I've installed the ojdbc jar in maven when I developed the project using java 8. Now I'm converting the project into java 7. While doing so, I'm facing issue with <code>ojdbc.jar</code> dependency in <code>pom.xml</code>. Its showing: </p>
  
  <blockquote>
    <p>Missing artifact com.oracle:ojdbc7:jar:12.1.0</p>
  </blockquote>
  
  <p>at oracle dependency tag. When I try to run the mvn install for ojdbc jar, that also throws an error.</p>
  
  <blockquote>
    <p>[ERROR] Failed to execute goal on project SlotBookingAvailability: Could not resolve dependencies for project org.logicInfo.oms:SlotBookingAvailability:war:0.0.
