Question

UPDATED (after reading Passing extra properties to maven archetype:generate):

I created my own archetype. The src/main/resources/archetype-resources/pom.xml:

 <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <groupId>$groupId</groupId>
    <artifactId>$artifactId</artifactId>
    <version>$version</version>
    <packaging>jar</packaging>

    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>$groupId</groupId>
                <artifactId>${3rdPartyDepsArtifactId}</artifactId>
                <version>${3rdPartyDepsVersion}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

    <properties>
        <maven.compiler.source>1.8</maven.compiler.source>
        <maven.compiler.target>1.8</maven.compiler.target>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
    </properties>

</project>

Want to use my own 3rd-party-deps-artifact and 3rd-party-deps-version parameters. So I added the src/main/resources/META-INF/maven/archetype-metadata.xml file:

<archetype-descriptor name="basic">
    <requiredProperties>
        <requiredProperty key="3rdPartyDepsArtifactId"/>
        <requiredProperty key="3rdPartyDepsVersion"/>
    </requiredProperties>
</archetype-descriptor>

Install archetype into my local repository. And then create artifact based on my custom archetype:

mvn archetype:generate -DarchetypeGroupId=test -DarchetypeArtifactId=test2 -DarchetypeVersion=1.0.0-SNAPSHOT -D3rdPartyDepsArtifactId=3rd-party-deps -D3rdPartyDepsVersion=1.0.0-SNAPSHOT -DgroupId=test3 -DartifactId=my_test -Dversion=1.0.0-SNAPSHOT

In the output I can see that both 3rdPartyDepsVersion and 3rdPartyDepsArtifactId are applied now: Confirm properties configuration:

groupId: ...
artifactId: ...
version: 1.0.0-SNAPSHOT
package: ...
3rdPartyDepsArtifactId: 3rd-party-deps
3rdPartyDepsVersion: 1.0.0-SNAPSHOT

But in the generated project, inside of dependencyManagement these properties are still ignored:

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>test3</groupId>
            <artifactId>${3rdPartyDepsArtifactId}</artifactId>
            <version>${3rdPartyDepsVersion}</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>

How can I force maven to use 3rdPartyDepsArtifactId and 3rdPartyDepsVersion properties?

Not sure whether this is possible as you want it but an alternative approach could be to include the property in your settings.xml (within a profile) or pass them within the maven command -D.

Using custom properties in your own maven archetype
