I have the exact same <plugin> configuration but I do not have any extensions
enabled:
<extensions>
<extension>
<groupId>jdbc.artifact.groupid</groupId>
<artifactId>jdbc-driver</artifactId>
<version>1.0</version>
</extension>
</extensions>
I am actually using the sun JDBC-ODBC bridge driver for this application [for
legacy reasons] so is that particular <extensions> configuration required?
Thanks,
James
