    - #### public FileSystemCompiler(CompilerConfiguration configuration)

    - #### public FileSystemCompiler(CompilerConfiguration configuration, CompilationUnit cu)

  - ### Method Detail

    - #### public static int checkFiles(String[] filenames)

    - #### public static void commandLineCompile(String[] args)

      Same as main(args) except that exceptions are thrown out instead of causing the VM to exit.

    - #### public static void commandLineCompile(String[] args, boolean lookupUnnamedFiles)

      Same as main(args) except that exceptions are thrown out instead of causing the VM to exit and the lookup for .groovy files can be controlled

    - #### public static void commandLineCompileWithErrorHandling(String[] args, boolean lookupUnnamedFiles)

      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

    - #### public void compile(String[] paths)

    - #### public void compile(File[] files)

    - #### public static CommandLine configureParser(FileSystemCompiler.CompilationOptions options)

    - #### public static void deleteRecursive(File file)

    - #### public static void displayHelp()

      Prints the usage help message for CompilationOptions to stderr.

      See Also:
        displayHelp(PrintWriter)
      Since:
        2.5

    - #### public static void displayHelp(PrintWriter writer)

      Prints the usage help message for the CompilationOptions to the specified PrintWriter.

      Since:
        2.5

    - #### public static void displayVersion()

      Prints version information to stderr.

      See Also:
        displayVersion(PrintWriter)

    - #### public static void displayVersion(PrintWriter writer)

      Prints version information to the specified PrintWriter.

      Since:
        2.5

    - #### public static void doCompilation(CompilerConfiguration configuration, CompilationUnit unit, String[] filenames)

    - #### public static void doCompilation(CompilerConfiguration configuration, CompilationUnit unit, String[] filenames, boolean lookupUnnamedFiles)

    - #### public static void main(String[] args)

      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:
