    //  If execution has been initiated from Gant or some context where the Groovy jar is already in the
    //  classpath when the Ant objects are created then we have no problems here, we can simply load the
    //  Groovyc Ant task into the Ant Project object.  However if the initiating context is Ant (e.g. the
    //  Gant Ant task is being used), then it might be that the Groovy jar was not in the Ant classpath when
    //  the Ant objects were instantiated.  If the Groovy jar was not in the classpath then the Groovyc Ant
    //  task cannot be loaded without specifying a path to the Groovy jar.  Fortunately we already know that
    //  Groovy is accessible since this code is actually running.  So to avoid any sense of doubt and
    //  uncertainty forcibly set the classpath to search for the Groovyc Ant task -- even though usually
    //  this is unecessary.  We are protecting here against a situation that is not the majority case but...
