Gradle Task: flywayRepair

Repairs the Flyway schema history table. This will perform the following actions:

  • Remove any failed migrations on databases without DDL transactions
    (User objects left behind must still be cleaned up manually)
  • Realign the checksums, descriptions and types of the applied migrations with the ones of the available migrations



> gradle flywayRepair
