依赖标记内各种参数的标记化在初始化期间失败

Question

以下依赖项是我的 pom.xml 文件的一部分，通过在 profile.xml 中选择适当的数据库配置文件，这些值将被正确替换。以下定义适用于 Maven 2.2.1，并在迁移到 Maven 3.0.2 后停止工作。如何解决这个问题？

    <dependency>
        <groupId>${db.groupId}</groupId>
        <artifactId>${db.artifactId}</artifactId>
        <version>${db.driver.version}</version>
        <scope>test</scope>
    </dependency>


<profile>
    <id>h2</id>
    <properties>
        <db.groupId>${db.h2.groupId}</db.groupId>
        <db.artifactId>${db.h2.artifactId}</db.artifactId>
        <db.type>h2</db.type>                <db.driver.version>${db.h2.driver.version</db.driver.version>
        <db.driver>${db.h2.driver}</db.driver>
    </properties>
</profile>

Answer 1

从 Maven 3.x 兼容性说明，

The support for profiles outside of the POM or the settings.xml has been 
removed in version 3.x and users that previously used this feature are advised 
to move the affected profiles into their settings.xml.
