    Modifier and Type | Method and Description
    --- | ---
    `static int` | `checkFiles(String[] filenames)`
    `static void` | `commandLineCompile(String[] args)` Same as main(args) except that exceptions are thrown out instead of causing the VM to exit.
    `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

    `void` | `compile(File[] files)`
    `void` | `compile(String[] paths)`
    `static Options` | `createCompilationOptions()`
    `static File` | `createTempDir()` Deprecated. Use `DefaultGroovyStaticMethods.createTempDir(java.io.File, String, String)` instead.

    - #### main

          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:
        `args` - command line arguments

      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
