Maven will not export runable JAR

Question

So I have a small maven project in eclipse, if I export a runable JAR and select:

Package required libaries into generated JAR

it works fine.

I should note that one of my JAR's is maven controlled (Univocity) the other is a local Oracle JDBC JAR. I want to include both of these in my runable JAR package so I can deploy a single JAR to production and execute it with a single command.

In my POM I added maven-assembly-plugin and when I use mvn package, I get a JAR with the Univocity library, but it skips the Oracle JAR.

How can I get it to bundle the Oracle JAR into the final output ?

Here is the POM:

        </executions>
        </plugin>
    </plugins>
  </build>
</project>

I did try using maven-dependency-plugin, but it didnt solve the problem bundling them into the single JAR.

Just a note - When I export the runable JAR in eclipse, it includes a: **org.eclipse.jdt.internal.jarinjarloader.** I presume this library handles unpacking the bundled JAR's. — Exie, Mar 23 '16 at 01:23

You have to install it manually because Oracle didn't let maven got any of their jars : so you got to install it manually with the command mvn install:install -Dfile=<path to file> ... and put it in your pom.xml like any other dependency without the <SystemPath> like this :

<dependencies>
    <dependency>
      <groupId>oracle.jdbc</groupId>
      <artifactId>ojdbc6</artifactId>
      <version>11.2.0.4</version>
    </dependency>
</dependecies>

In my case : when i want to deploy my application in tomcat : i got to put the jar ojdbc6 directly in the folder lib of tomcat.
