To enable automatic YourKit profiling as part of the Maven build, specify the profiler in the plugin configuration to be 'yourkit'.
Further, add a 'profilerContext' element, refering to the net.sourceforge.basher.YourKitProfilerContext in your BasherContext.
A sample is shown below:
...
<configuration>
...
<!-- This configures Basher to enable the YourKit profiling agent
<profiler>yourkit</profiler>
...
<basherContexts>
<basherContext implementation="net.sourceforge.basher.BasherContext">
...
<!-- This controls the YourKit profiling agent -->
<profilerContext implementation="net.sourceforge.basher.YourKitProfilerContext"/>
...
</basherContext>
</basherContexts>
</configuration>
...
