pluginArtifactMap.get( "org.apache.maven.surefire:surefire-booter" );

in maven-surefire-plugin I am trying to determine the reason for this loc in SurefirePlugin.java

pluginArtifactMap.get( "org.apache.maven.surefire:surefire-booter" );

if booter is absent you get "Unable to locate surefire-booter in the list of plugin artifacts"

is this a configuration parameter?

I guess Im trying to understand reason for 2 plugins to be loaded to execute one plugin functionality

thanks.
