如何从外部项目的 pom 执行 maven liquibase pom？

Question

My maven project is dependent on a database schema created through another external project via liquibase. For testing my project, I need to generate this database structure on my machine. Is there a way to specify the liquibase project details(group id, artifact, version,etc. and requisite liquibase parameters) in my project's pom itself so that the db structure is generated before any tests are executed.

PS: I know I can use something like below if the project actually exists in my machine:

<plugins>
    <plugin>
        <groupId>org.codehaus.mojo</groupId>
        <artifactId>exec-maven-plugin</artifactId>
        <version>1.1</version>
        <executions>
            <execution>
                <id>create-unitttest-db-schema</id>
                <phase>process-test-resources</phase>
                <goals>
                    <goal>exec</goal>
                </goals>
                <configuration>
                    <skip>${skipSchemaCreation}</skip>
                    <executable>mvn</executable>
                    <arguments>
                        <argument>-f</argument>
                        <argument>../proj-liquibase-db/pom.xml</argument>
                        <argument>-P${proj.test.liquibase.create.profile},create</argument>
                        <argument>clean</argument>
                        <argument>install</argument>
                        <argument>-DdefaultSchemaName=${proj.test.schema.unittest}</argument>
                    </arguments>
                </configuration>
            </execution>
        </executions>
    </plugin>
</plugins>

I want to specify the proj-liquibase-db 's project coordinates here instead of the path to its pom file.

PPS: If it is not possible, then please let me know and suggest some alternatives as I am really stuck here.

Answer 1

您应该通过在类路径中添加项目 jar 并提供其他必要参数（如数据库详细信息等）来执行 liquibase jar，而不是依赖：解包。

Answer 2

you can unpack the artifact generated by the project containing the liquibase xml files in a subfolder of your "target" directory using the dependency plugin. The goal should be dependency:unpack. Then you just have to configure liquibase in your test classes in order to load these files.
