Creating temporary database that works across maven test phases?

For this case I have created the derby-maven-plugin. It’s available from Maven Central, so you don’t need to add any extra repositories or anything.

You could use it like this:

    <project ...>
        <build>
            <plugins>
                <plugin>
                    <groupId>org.carlspring.maven</groupId>
                    <artifactId>derby-maven-plugin</artifactId>
                    <version>1.8</version>
                    <configuration>
                        <basedir>${project.build.directory}/derby</basedir>
                        <port>1527</port>
                    </configuration>
                    <executions>
                        <execution>
                            <id>start-derby</id>
                            <phase>pre-integration-test</phase>
                            <goals>
                                <goal>start</goal>
                            </goals>
                        </execution>
                        <execution>
                            <id>stop-derby</id>
                            <phase>post-integration-test</phase>
                            <goals>
                                <goal>stop</goal>
                            </goals>
                        </execution>
                    </executions>
                </plugin>
            </plugins>
        </build>
    </project>
