Confluence-plugins-platform-pom version 9.0.0+ not available

Hello,

I’m trying to update our plugin for Confluence 9. As far as I can tell, the following is the recommended way to manage dependency versions:

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>com.atlassian.confluence</groupId>
            <artifactId>confluence-plugins-platform-pom</artifactId>
            <version>${confluence.version}</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>

However, that dependency can’t be resolved.

[ERROR] Non-resolvable import POM: The following artifacts could not be resolved: com.atlassian.confluence:confluence-plugins-platform-pom:pom:9.0.0 (absent): Could not find artifact com.atlassian.confluence:confluence-plugins-platform-pom:pom:9.0.0 in maven-central (https://repo1.maven.org/maven2/)

There appear to be no 9.0.0+ versions available. Is this still the recommended way to do things? Did I do something wrong?

As a side-note, atlas-create-confluence-plugin (using Atlassian Plugin SDK 9.1.1) creates a project with extremely old dependencies - maybe this should be updated?

EDIT: atlas-run-standalone --product confluence -v 9.0.0 results in error below, so that’s another dependency which appears to be missing.
