External JARs with Drools Workbench do not resolve on compilation

Question

Summary

I have a drools workbench server that I want to push data model jars to from maven. I can push jars to it, but when I do, the artefacts do not resolve. If I try to upload the artefacts manually through the drools UI, I get other maven errors.

Details

I have a drools installation of drools and KIE 7.24 (and 23) (https://hub.docker.com/r/jboss/jbpm-server-full/) running in a local docker container. I want to push data models to workbench. My pom.xml of the project containing the facts looks like

<project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"
         xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <modelVersion>4.0.0</modelVersion>
    <properties>
        <maven.compiler.release>11</maven.compiler.release>
    </properties>

    <build>
        <plugins>
            <plugin>
                <groupId>org.kie</groupId>
                <artifactId>kie-maven-plugin</artifactId>
                <version>7.24.0.Final</version>
                <extensions>true</extensions>
            </plugin>
        </plugins>
    </build>

    <distributionManagement>
        <repository>
            <id>workbench</id>
            <url>http://localhost:8080/business-central/maven2</url>
        </repository>
    </distributionManagement>
</project>

A mvn deploy on the host succeeds and builds. When I log into the drools container, I can verify that all the files are in $DROOLS_HOME/bin/repositories/kia/global and when I bring up the artifacts screen, they are visible in the list.

When I try to add them as a project dependency, I get warnings from drools

07:49:16,790 WARN  [org.appformer.maven.integration.MavenRepository] (default task-50) Unable to resolve artifact: decisions:fact:1.0.0
07:49:16,791 ERROR [org.kie.scanner.MavenClassLoaderResolver] (default task-50) Dependency artifact not found for: decisions:fact:1.0.0

Everything in the drools workbench maven repositories looks perfectly ok, but no matter what I do, the artifact will not resolve.

If I try to upload it manually to the artifact store using the workbench admin repository tool, I get a huge stack trace from drools:

Neither the drools manual or any references seem to have advice.
