Migrations in sqlite returns no error but it doesn't do anything

Which version and edition of Flyway are you using?

6.4.4 (latest as today)

Which client are you using? (Command-line, Java API, Maven plugin, Gradle plugin)

Gradle Plugin

Which database are you using (type & version)?

Sqlite 3.28.0 org.xerial:sqlite-jdbc:3.28.0

Which operating system are you using?

macOS Catalina 10.15.4 (19E287) Java info: openjdk 11.0.2 2019-01-15 OpenJDK Runtime Environment 18.9 (build 11.0.2+9) OpenJDK 64-Bit Server VM 18.9 (build 11.0.2+9, mixed mode)

What did you do?

I replaced postgres with sqlite on a legacy Spark project with Gradle. Everything works well (app and tests) if I create the database and run SQL from migrations manually using a 3rd. party db client. The issue here is flywayMigrate command is not returning errors as if it ran correctly. But no database was created anywhere. Even if I created an empty file with the same name, it doesn’t apply migrations on it.

Repo: https://github.com/TwilioDevEd/browser-calls-spark/tree/next Note: Make sure you are on the next branch.

Easy to reproduce:

1. Just clone, check out that branch
2. source .env.example you don’t need the rest of the variables.
3. Execute the migration command ./gradle flywayMigrate.

As a workaround, I had to create the DB manually using sqlite3 CLI so CI can pass.

What did you expect to see?

• Creating of the mydb.db file
• Migrations run on that file

What did you see instead?

@po5i if you use jdbc:h2:file:./mydb, gradle flyway will create db file at ~/.gradle/

$ find ~/.gradle/ -name '*.db'
/Users/sinkcup/.gradle/daemon/6.4.1/mydb.mv.db

if you want db file be created to current dir, you should use this config:

flyway {
    url = "jdbc:h2:file:${System.getProperty('user.dir')}/database"
    user = 'sa'
}

We have now documented how gradle relative paths work and this work around. Thank you.
