properties substitution problem in pom

There's something about properties substition that I don't understand.

I'm getting the error about a missing artifact, the coordinates for the artifact it's complaining about are

jdbc-groupId-placeholder:jdbc-artifactId-placeholder:jar:version-jdbc-placeholder

And the path message is

  Path to dependency:
        1) edu.berkeley.ist.cars:cars-war:war:1.1-SNAPSHOT
        2) edu.berkeley.ist.cars:cars-web:jar:1.1-SNAPSHOT
        3) edu.berkeley.ist.cars:cars-download:jar:1.1-SNAPSHOT
        4) jdbc-groupId-placeholder:jdbc-artifactId-placeholder:jar:version-jdbc

The cars-web and cars-download are built from a multi module parent pom, which contains (along with the usual stuff)

    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>${jdbc.groupId}</groupId>
                <artifactId>${jdbc.artifactId}</artifactId>
                <version>${version.jdbc}</version>
            </dependency>
            <!-- etc. -->
        </dependencies>
    </dependencyManagement>
    <properties>
        <jdbc.groupId>jdbc-groupId-placeholder</jdbc.groupId>
        <jdbc.artifactId>jdbc-artifactId-placeholder</jdbc.artifactId>
        <version.jdbc>version-jdbc-placeholder</version.jdbc>
        <!-- etc. -->
    </properties>
    <profiles>
        <profile>
            <id>test</id>

            <activation>
                <activeByDefault>false</activeByDefault>
            </activation>

            <properties>
                <jdbc.driverClass>com.mysql.jdbc.Driver</jdbc.driverClass>
                <jdbc.groupId>mysql</jdbc.groupId>
                <jdbc.artifactId>mysql-connector-java</jdbc.artifactId>
                <version.jdbc>5.1.6</version.jdbc>
                <!-- etc. -->
            </properties>
        </profile>
    </profiles>

I'm getting the error when I run "mvn -Ptest package" in the cars-war directory.

In the cars-parent directory I did "mvn -Ptest clean package install" and it installed the jars in my ~/.m2 repo.

The cars-war pom.xml only has a dependency on cars-web.

The pom for cars-download contains

        <dependency>
            <groupId>${jdbc.groupId}</groupId>
            <artifactId>${jdbc.artifactId}</artifactId>
        </dependency>

(When I look at the .pom files in my ~/.m2 repo for cars-download and the parent they contain the ${} placeholders, not the substituted values, which puzzles me.)

Re: properties substitution problem in pom

I got it to work by being less aggressive about using property placeholders; now the dependencyManagement dependencies use a specific groupId and artifactId.  Likewise for the dependency section in the cars-download pom.  But I'm still confused about why it wasn't working.  It seems like it's not using the properties I gave in the profile.
