[SOLVED] No database found to handle error with flyway postgresql

No database found to handle error with flyway postgresql

I am new to Java, trying to setup a first API.

I have a Springboot app which connects to a postgresql database on a docker container.

I do manage to access the database from the app, so the database in on and accessible as per my application.properties:

spring.datasource.driver-class-name=org.postgresql.Driver
spring.datasource.url=jdbc:postgresql://localhost:5433/portfolio
spring.datasource.username=postgres
spring.datasource.password=123456
spring.datasource.driverClassName=org.postgresql.Driver
spring.jpa.show-sql=true
spring.jpa.properties.hibernate.format_sql=true

spring.jpa.hibernate.ddl-auto=none

When attempting to setup migrations with flyway with the command:

mvn flyway:migrate

I get the error:

No database found to handle jdbc:postgresql://localhost:5433/portfolio

This is how the pom.xml for flyway looks like:

            <plugin>
            <groupId>org.flywaydb</groupId>
            <artifactId>flyway-maven-plugin</artifactId>
            <version>10.7.1</version>
            <configuration>
                <sqlMigrationSeparator>__</sqlMigrationSeparator>
                <locations>
                    <location>filesystem:src/main/resources/db/migration/portfolio</location>
                </locations>
                <url>jdbc:postgresql://localhost:5433/portfolio</url>
                <user>postgres</user>
                <password>123456</password>
            </configuration>
            <dependencies>
                <dependency>

                    <artifactId>flyway-core</artifactId>
                    <version>10.7.1</version>
                </dependency>
            </dependencies>
        </plugin>

EDIT - adding docker-compose as requested

Solution

The error says No database found to handle jdbc:postgresql. This doesn't mean that the database is not accessible/running, but that Flyway can't handle the PostgreSQL database type. You should add this to the Maven Plugin dependencies:

<dependency>
    <groupId>org.flywaydb</groupId>
    <artifactId>flyway-database-postgresql</artifactId>
    <version>11.3.4</version>
</dependency>

Please note: latest Flyway version is 11.3.4
