color NO n/a (Command line flag only) Whether to colorize output. If set to 'auto', will print color if a console is detected. Defaults to 'auto'. (always, never, or auto)
jarDirs NO <install-dir>/jars Comma-separated list of directories containing JDBC drivers and Java-based migrations
callbacks NO Comma-separated list of fully qualified class names of Callback implementations to use to hook into the Flyway lifecycle.
skipDefaultCallbacks NO false Whether default built-in callbacks (sql) should be skipped. If true, only custom callbacks are used.

If false, files with invalid names are ignored and Flyway continues normally. If true, Flyway fails fast and lists the offending files.
