UPDATED for a dependency definition example
Add the following repository definition to your BuildConfig.groovy
mavenRepo "https://code.lds.org/nexus/content/groups/main-repo"
In your dependencies section the following should appear:
runtime 'com.oracle:ojdbc6:11.2.0.3'
A better way is to install manually the Oracle driver to your corporate Repository(Artifactory, Nexus, Archiva, file server, etc.)
