Configure jetty with extraClasspath property.
Configuration
Setup extraClasspath property in hotswap-agent.properties.
#
# Add this classpath prior to application classpath.
# This may be useful for example in multi module maven project, where you do not need to build JAR file
# after each change.
#
# Note that there must be a plugin that will provide actual replacement such as JettyPlugin for Jetty servlet container.
