Hello! I wanted to build the current branch-2.0 of Atlas but it didn't work simply by following the Build Process of README.txt.
The reason for wanting to build from source is that spark-atlas-connector recommends using Atlas 2.1.0 ( https://github.com/hortonworks-spark/spark-atlas-connector#create-atlas-models ), but I couldn't find such release. Not released yet? So, to build Atlas from source I tried: mvn clean install ..but it failed with errors like: [ERROR] Failed to execute goal on project atlas-testtools: Could not resolve dependencies for project org.apache.atlas:atlas-testtools:jar:2.1.0-SNAPSHOT: The following artifacts could not be resolved: org.restlet.jee:org.restlet:jar:2.3.0, org.restlet.jee:org.restlet.ext.servlet:jar:2.3.0: Could not find artifact org.restlet.jee:org.restlet:jar:2.3.0 in central (https://repo1.maven.org/maven2) -> [Help 1] This way I got a bit further with the build: mvn -s ~/.m2/settings-apache-atlas.xml clean install -DskipTests=true This failure I manually mitigated by removing hortonworks-nexus from the settings as far as it wasn't absolutely required for finding some dependency (and I had previously fetched that to the local .m2/): [ERROR] Failed to execute goal org.apache.maven.plugins:maven-site-plugin:3.7:site (default) on project atlas-docs: SiteToolException: The site descriptor cannot be resolved from the repository: ArtifactResolutionException: Unable to locate site descriptor: Could not transfer artifact org.apache:apache:xml:site_en:17 from/to hortonworks-nexus (http://nexus-private.hortonworks.com/nexus/content/groups/public/): Connect to nexus-private.hortonworks.com:80 [nexus-private.hortonworks.com/54.173.242.72] failed: Operation timed out (Connection timed out) I wonder what would be a proper way to manage that ( maybe this: https://stackoverflow.com/a/41810983/1068385 – but might be not enough). Having hortonworks-nexus is slowing down dependency fetching a lot whenever the dependency is not found in central. Maybe it could be avoided by adding all of these explicitly before it: https://repo.hortonworks.com/content/repositories/releases/ https://repository.apache.org/content/groups/snapshots/ https://repository.apache.org/content/groups/staging/ https://repository.apache.org/content/groups/public/ https://maven.java.net/content/groups/public/ https://repository.jboss.org/nexus/content/groups/public/ ..I didn't try that though. Is there some official way configure the maven repos for an Atlas build? Could the project pom.xml define the required maven repos? If there's some automated CI builder for Atlas, how does that work? Also, README.txt instructs to build with 'mvn install' first, and only then 'package -Pdist'. Is 'install' (to local .m2) really required for building the packages? Thanks! I used the following settings, saved as ~/.m2/settings-apache-atlas.xml: <?xml version="1.0" encoding="UTF-8"?> <settings xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.1.0 http://maven.apache.org/xsd/settings-1.1.0.xsd"; xmlns="http://maven.apache.org/SETTINGS/1.1.0"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";> <profiles> <profile> <id>atlas</id> <repositories> <repository> <id>central</id> <name>Maven Central</name> <url>http://repo1.maven.org/maven2</url> <snapshots> <enabled>false</enabled> </snapshots> </repository> <repository> <id>oracleReleases</id> <name>Oracle Released Java Packages</name> <url>http://download.oracle.com/maven</url> <releases> <enabled>true</enabled> </releases> <snapshots/> </repository> <repository> <id>maven.restlet.org</id> <name>maven.restlet.org</name> <url>http://maven.restlet.org</url> <releases> <enabled>true</enabled> </releases> </repository> <repository> <releases> <enabled>true</enabled> </releases> <snapshots> <enabled>true</enabled> </snapshots> <id>clojars</id> <url>https://clojars.org/repo/</url> </repository> <!-- <repository> <id>hortonworks-nexus</id> <name>nexus repo</name> <url>http://nexus-private.hortonworks.com/nexus/content/groups/public/</url> </repository> --> </repositories> </profile> </profiles> <activeProfiles> <activeProfile>atlas</activeProfile> </activeProfiles> </settings>
