Command-line: validate

Validate applied migrations against resolved ones (on the filesystem or classpath) to detect accidental changes that may prevent the schemas from being recreated exactly.

Validation fails if

differences in migration names, types or checksums are found
versions have been applied that aren't resolved locally anymore
versions have been resolved that haven't been applied yet

Usage

> flyway [options] validate
