org.alfresco:alfresco-java-sdk:pom:5.2.0 was not found in https://repo.maven.apache.org/maven2

This artifact is not available in Maven Central.

Add following lines to your pom.xml file with the Alfresco Maven Repository settings:

    <repositories>
        <repository>
            <id>alfresco-public</id>
            <url>https://artifacts.alfresco.com/nexus/content/groups/public</url>
        </repository>
    </repositories>
