Jooq with flyway and testconteiners creates new container per run

I want to use flyway with testcontainers for jooq generation. For this purpose I have 2 plugins

<plugin>
            <groupId>org.flywaydb</groupId>
            <artifactId>flyway-maven-plugin</artifactId>
            <version>7.14.0</version>
            <executions>
                <execution>
                    <phase>generate-sources</phase>
                    <goals>
                        <goal>migrate</goal>
                    </goals>
                </execution>
            </executions>
            <configuration>
                <url>jdbc:tc:postgresql:10://localhost:7432/test</url>
                <user>test</user>
                <password>test</password>
                <driver>
                    org.testcontainers.jdbc.ContainerDatabaseDriver
                </driver>
                <locations>
                    <location>filesystem:src/main/resources/db/migrations</location>
                </locations>
            </configuration>
        </plugin>
        <plugin>
            <groupId>org.jooq</groupId>
            <artifactId>jooq-codegen-maven</artifactId>
            <version>3.14.15</version>

            <executions>
                <execution>
                    <id>java-generator</id>
                    <phase>generate-sources</phase>
                    <goals>
                        <goal>generate</goal>
                    </goals>
                </execution>
            </executions>

            <configuration>
                <jdbc>
                    <driver>org.testcontainers.jdbc.ContainerDatabaseDriver</driver>
                    <url>jdbc:tc:postgresql:10://localhost:7432/test</url>
                    <user>test</user>
                    <password>test</password>
                </jdbc>

                <generator>
                    <database>
                        <name>org.jooq.meta.postgres.PostgresDatabase</name>
                        <includes>.*</includes>
                        <inputSchema>public</inputSchema>
                    </database>

                    <generate/>

                    <target>
                        <packageName>com.test</packageName>
                        <directory>target/generated-sources/jooq</directory>
                    </target>
                </generator>
            </configuration>
        </plugin>

So, I see that flyway started tc, applied all scripts and then jooq starts its’s own container and tried to generate entities, but there are nothing. Could you please suggest how to handle this?

Answer

You have to start the test container first like this:

        <!-- Start Testcontainer -->

                            db = new org.testcontainers.containers.PostgreSQLContainer("postgres:12.7")
                                .withUsername("${db.username}")
                                .withDatabaseName("jtaf4")
                                .withPassword("${db.password}")
                            db.start()
                            project.properties.setProperty('db.url', db.getJdbcUrl())
                        </source>
