        Throws:

      • reverse

        public static <T> T[] reverse​(T[] array)

      • file

        public static java.io.File file​(java.lang.String... pathParts)

      • file

        public static java.io.File file​(java.io.File f,
                                java.lang.String... pathParts)

      • pathFrom

        public static java.nio.file.Path pathFrom​(java.net.URL localArtifactUrl)

      • intArrayToList

        public static java.util.List<java.lang.Integer> intArrayToList​(int[] ints)

      • parseInt

        public static int parseInt​(java.lang.String valueFor)

      • sneakyThrow

        public static <T extends java.lang.Throwable> java.lang.RuntimeException sneakyThrow​(java.lang.Throwable t)
                                                                              throws T extends java.lang.Throwable
        Re-throw t (even if it's a checked exception) without requiring a throws declaration.

        This function declares a return type of RuntimeException but will never actually return a value. This allows you to use it with a throw statement to convince the compiler that the current branch will not complete. 

        
 throw Util.sneakyThrow(new IOException());
