<p>I want to simplify my execution of a Groovy script that makes calls to an Oracle database. How do I add the ojdbc jar to the default classpath so that I can run:</p>

<pre><code>groovy RunScript.groovy
</code></pre>

<p>instead of:</p>

<pre><code>groovy -cp ojdbc5.jar RunScript.groovy
</code></pre>

```
groovy
```
is just a wrapper script for the Groovy JAR that sets up the Java classpath. You could modify that script to add the path to your own JAR, as well, I suppose.
