Settings are loaded in the following order (higher items in the list take precedence over lower ones):

1. Command-line arguments
2. Environment variables
3. Standard input
4. Custom config files
   TOML Configuration file (.toml) takes precedence over a legacy configuration (.conf) file and then the following filesystem locations
   1. {workingDirectory}/
   2. {executionDir}/
   3. {userhome}/
   4. {installDir}/conf/
5. Flyway command-line defaults

This means that if flyway.url is both present in a config file and passed as -url= from the command-line, the command-line argument will take precedence and be used.

If you are unsure about where Flyway is taking its configuration from then adding -X (capital X) to the command line will enable extended debugging. ./flyway info -X
