Using Flyway to load data conditionally per environment

Question

Does flyway support conditional execution of a script, per environment?

For example, if I have test data, can I create a test data script folder thats only loaded i

Answer 1

Maven profiles did not give me the flexibility I wanted. I came up with a strategy that uses ant to merge files. This allows me to have common scripts and then included additional data depending on the deploy type eg. prod, dev.

This is my project structure:

├── build.xml
├── database.properties
├── database.properties.template
├── lib
│   └── ant-contrib-1.0b3.jar
├── pom.xml
└── sql
    ├── common
    │   ├── V1.0__.sql
    │   ├── V1.2.1__.sql
    │   └── V1.3__.sql
    ├── dev
    │   ├── V1.0__.sql
    │   └── V1.3__.sql
    └── prod
        └── V1.0__.sql

database.properties.template file in the root folder, before running this has to manually be copied to database.properties and the username and password can be entered. database.properties should be ignored by VCS so that passwords don't end up in the repo.

deployType scripts are merged into the src/main/resources/db/migrate directory, here is the ant script that does that, note that scripts that are to be merged have the same name:

This ant file is executed by maven, here is the pom config:

Should you require different data for different client distributions you could add dist directories into the sql directory and they could contain deployType sub directories.

Add the dist property to the database.properties.template file and then modify the append target in the build.xml to look like this:
