Maven ojdbc jar dependency error: package oracle.jdbc does not exist

The ojdbc jar is not in public maven repositories. You can add the jar to local repository manually.

Download the jar from:

• oracle site
• copy from your oracle database server ( {ORACLE_HOME}\jdbc\lib\ojdbc6.jar )

Install in your repository

mvn install:install-file -Dfile={Path/to/your/ojdbc.jar} -DgroupId=com.oracle -DartifactId=ojdbc6 -Dversion=11.2.0 -Dpackaging=jar

Use in your pom

   <dependency>
        <groupId>com.oracle</groupId>
        <artifactId>ojdbc6</artifactId>
        <version>11.2.0</version>
   </dependency>

Oracle JDBC drivers are accessible from Oracle Maven Repository with some additional security related steps.
