      Primary entry point for compiling from the command line (using the groovyc script). If calling inside a process and you don't want the JVM to exit on an error call commandLineCompile(String[]), which this method simply wraps
      Parameters:
        `args` - command line arguments
        `lookupUnnamedFiles` - do a lookup for .groovy files not part of the given list of files to compile
