Two ways to solve this:
- have the user specify which dependency to use via configuration:
<plugin>
...
<configuration>
<jdbcDriver>com.mysql:mysql-driver</jdbcDriver>
</configuration>
</plugin>
...
<dependency>
<groupId>com.mysql</groupId>
<artifactId>mysql-driver</artifactId>
<version>5.0.0</version>
</dependency>
- add the dependency to the plugin declaration and just use the
current classloader (probably the best)
<plugin>
...
<dependency>
<groupId>com.mysql</groupId>
<artifactId>mysql-driver</artifactId>
<version>5.0.0</version>
</dependency>
</plugin>
Cheers,
Brett
