使用 Maven + Flyway 迁移/清理/等多个数据库

Question

我有一个包含多个数据库的 Maven 项目，我们正在使用 Flyway 进行版本控制：

        <plugin>
            <groupId>org.flywaydb</groupId>
            <artifactId>flyway-maven-plugin</artifactId>
            <version>6.0.8</version>
            <dependencies>
                <dependency>
                    <groupId>org.postgresql</groupId>
                    <artifactId>postgresql</artifactId>
                    <version>42.2.5</version>
                </dependency>
            </dependencies>
            <configuration>
                <configFiles>/etc/hG/application.properties</configFiles>
            </configuration>
            <executions>
                <execution>
                    <id>wave</id>
                    <phase>generate-sources</phase>
                    <goals>
                        <goal>migrate</goal>
                        <goal>info</goal>
                    </goals>
                    <configuration>
                        <url>${wave.flyway.url}</url>
                        <user>${db.aws.user}</user>
                        <password>${db.aws.pass}</password>
                        <driver>${flyway.driver}</driver>
                        <locations>
                            <location>
                                filesystem:src/main/resources/wave/migration
                            </location>
                        </locations>
                    </configuration>
                </execution>
                <execution>
                    <id>tracks</id>
                    <phase>generate-sources</phase>
                    <goals>
                        <goal>migrate</goal>
                        <goal>info</goal>
                    </goals>
                    <configuration>
                        <url>${tracks.flyway.url}</url>
                        <user>${db.timescale.tracks.user}</user>
                        <password>${db.timescale.tracks.pass}</password>
                        <driver>${flyway.driver}</driver>
                        <locations>
                            <location>
                                filesystem:src/main/resources/tracks/migration
                            </location>
                        </locations>
                    </configuration>
                </execution>
                <execution>
                    <id>osm</id>
                    <phase>generate-sources</phase>
                    <goals>
                        <goal>migrate</goal>
                        <goal>info</goal>
                    </goals>
                    <configuration>
                        <url>${osm.flyway.url}</url>
                        <user>${db.osm.user}</user>
                        <password>${db.osm.pass}</password>
                        <driver>${flyway.driver}</driver>
                        <locations>
                            <location>
                                filesystem:src/main/resources/osm/migration
                            </location>
                        </locations>
                    </configuration>
                </execution>
            </executions>
        </plugin>

我希望能够从命令行使用 mvn flyway:clean、flyway:migrate、flyway:info 命令，但是它们不起作用：

[ERROR] Failed to execute goal org.flywaydb:flyway-maven-plugin:6.0.8:clean (default-cli) on project DataServices: org.flywaydb.core.api.FlywayException: Unable to connect to the database. Configure the url, user and password!

我怀疑这是因为我没有在用于配置的 application.properties 文件中使用标准的飞行路线属性，但是这也向我表明，如果我要使用这些标准属性，它只会适用于单一数据库。有没有一种方法可以设置我的 maven 文件来清理每个数据库，或者甚至根据执行的 ID（wave、tracks、osm）来执行这些操作，以便它们使用这些属性？

更新：我想我可以通过制作另外 3 个在 clean 阶段工作的执行块来重复我用于迁移的清理过程，如下所示： >

                <execution>
                    <id>wave-clean</id>
                    <phase>clean</phase>
                    <goals>
                        <goal>clean</goal>
                    </goals>
                    <configuration>
                        <url>${wave.flyway.url}</url>
                        <user>${db.aws.user}</user>
                        <password>${db.aws.pass}</password>
                        <driver>${flyway.driver}</driver>
                        <locations>
                            <location>
                                filesystem:src/main/resources/wave/migration
                            </location>
                        </locations>
                    </configuration>
                </execution>

...并重复其他两个。但是，现在我收到此错误：

[INFO] --- flyway-maven-plugin:7.11.4:clean (wave-clean) @ DataServices ---
[WARNING] Discarding INCOMPLETE dataSource configuration! flyway.url must be set.

Answer 1

我在问题中发布的更新走在正确的轨道上，但我没有意识到我没有读取干净生命周期的属性，所以我不得不向我的 {{1} } 块：

properties-maven-plugin

这读取了配置文件并消除了错误，现在 <execution> <id>pre-clean-read-proj-props</id> <phase>pre-clean</phase> <goals> <goal>read-project-properties</goal> </goals> <configuration> <files> <file>/etc/hG/application.properties</file> </files> </configuration> </execution> 按预期清理所有数据库！
