This is a property resolver which can be used to derive values based upon user defined placeholder values.

This resolver expects an entry of the form ${placeholder.PLACEHOLDER_NAME} where PLACEHOLDER_NAME is defined under the [flyway.placeholders] namespace.

Note: Only user defined placeholders are supported, default ${flyway:property} style placeholders are not supported.

Usage

Flyway Desktop

This can't be set in a config file via Flyway Desktop, although it will be honoured.
