Missing Vaadin dependencies from org.vaadin.artur – Docker

I am experimenting with the Vaadin Flow framework for creating a web application. I have configured and downloaded the test application as a Maven project, as described here: https://start.vaadin.com/app/

However, this project is unable to download two required dependencies from Maven central:

<dependency>
    <groupId>org.vaadin.artur</groupId>
    <artifactId>a-vaadin-helper</artifactId>
    <version>1.7.1</version>
</dependency>

and

<dependency>
    <groupId>org.vaadin.artur</groupId>
    <artifactId>spring-data-provider</artifactId>
    <version>2.0.2</version>
</dependency>

The required repo is already in my POM:

<repository>
    <id>Vaadin Directory</id>
    <url>http://vaadin.com/nexus/content/repositories/vaadin-addons</url>
    <snapshots>
        <enabled>false</enabled>
    </snapshots>
</repository>

When I download the JARs manually and add them to my local .m2 repo, the project builds fine, so there is a workaround. But I still would like to understand why these dependencies are not retrieved from Maven. Also, this is a problem for the docker build, which fails, because it doesn’t access my local Maven repo, of course.

Any ideas? Thanks a lot.

    I found the error. It was due to our internal repository setup. We're using Nexus, which also acts as a Maven Central proxy. Since these two dependencies are not listed on Central, I had to add the JARs manually to Nexus and also configure the Nexus repo in the POM.xml. The build then worked ok.

    Not sure where you got the repository from but if you go to https://start.vaadin.com and download an app, the pom.xml contains

            <!-- Repository used by many Vaadin add-ons -->
        <repository>
            <id>Vaadin Directory</id>
            <url>https://maven.vaadin.com/vaadin-addons</url>
            <snapshots>
                <enabled>false</enabled>
            </snapshots>
        </repository>

    which should be the correct repository URL
