[jetty-users] Jetty Maven Plugin: How can I add Jars to "lib/ext"?

[Gerrit Hübbers <gerrit.huebbers@xxxxxxxxx>]

I need to have additional libraries/jars available to the Jetty Maven
Plugin when starting it with "mvn jetty:run".

With the Jetty "start.jar" mechanism, I simply have to put the
required libraries into Jetty's directory "lib/ext" and they will be
added to Jetty automatically (as pointed out in
http://wiki.eclipse.org/Jetty/Reference/Jetty_Classloading#Adding_Extra_Classpaths_to_Jetty
).

For an example, I need "MySQL Connector/J" at Jetty startup time. With
the "start.jar" mechanism, I've put
"mysql-connector-java-5.1.22-bin.jar" into "lib/ext". Then my setup
looks like the following and works smoothly.

How can I make "mysql-connector-java-5.1.22-bin.jar" available to
Jetty when using the Jetty Maven Plugin?

Thanks!
