Apache Atlas fails to run: Maven clean install fails to install Kafka-Hook

[Chuka-J-Uzo]

Apache Atlas Web UI runs, but we are unable to connect the Kafka-Hook to it or even install other hooks required for it to run.

We attempted to solve the problem by running the mvn clean install -DskipTests command in the root directory of our Kafka Bridge project folder, where the pom.xml file is located. In this case, we ran it in the kafka-bridge directory, as that's where the pom.xml file is located, but we got the following error:

The error message suggested that Maven was not able to find the artifact "org.apache.atlas:atlas-buildtools:jar:1.0". So one possible solution was to add the repository where this artifact is hosted to our Maven settings.xml file. Here are the steps you followed without success:

1. Open our settings.xml file located in ~/.m2/settings.xml with our text editor.
2. Add the following code snippet inside the tag:

<repository>
    <id>atlas-repository</id>
    <name>Apache Atlas Repository</name>
    <url>https://repository.apache.org/content/repositories/releases/</url>
</repository>

3. Save the settings.xml file and re-run the mvn clean install -DskipTestscommand.

The above addition failed, then we tried one last option, which entailed adding the following repository to our pom.xml file:

<repositories>
  <repository>
    <id>atlas-repository</id>
    <name>Apache Atlas Repository</name>
    <url>https://repository.apache.org/content/groups/public/</url>
  </repository>
</repositories>

This addition still did not work. For this reason, we couldn't successfully install the Kafka-Hook required for Apache Atlas to run and pull Kafka topics. This hindered our ability to run Atlas for Data Discovery, Data Lineage and Data Governance in general.

A solution will be most appreciated!
