A retry tool based on google guava, you can use it to retry your task easily.

Only 2 classes you need to know: Retry, RetryBuilder.

Example: ``` Retryer retryer = new RetryerBuilder() .times(3) .interval(10, SECONDS) .whenThrow(timeoutException()) .whenReturn(errorResponse()) .build();

Response response = retryer.callWithRetry(new Callable() { public Response call() throws Exception { return removeService.upload(request); } });

```

Retry condition: private static Predicate<Exception> timeoutException() { return new Predicate<Exception>() { public boolean apply(Exception exception) { if (exception instanceof TimeoutException) { return exception.getMessage().startsWith("Retryable"); } return false; } }; }
