Apache Ranger 0.5 build errors – How to fix them

I recently came accross some maven errors while building Apache Ranger 0.5 leading to a failure while building the HDFS Security Plugin and the Storm Security Plugin.

To get rid of the error just change the version of the maven-assembly-plugin in Ranger’s main pom.xml from

<version>2.2-beta-5</version>

to

<version>2.3</version>

…, add the following repository definitions to the main pom.xml

<repository>
<id>conjars</id>
<name>Concurrent Conjars repository</name>
<url>http://conjars.org/repo</url>
<layout>default</layout>
</repository>
<repository>
<id>clojars.org</id>
<url>http://clojars.org/repo</url>
</repository>

…, add the following dependency to the storm-agent/pom.xml:

<dependency>
<groupId>ring</groupId>
<artifactId>ring-jetty-adapter</artifactId>
<version>0.3.11</version>
</dependency>

Now you should be able to build ranger. If you are facing issues with a missing pom.xml for the dependency tomcat:common-el then add the following repository to the main pom.xml:

<repository>
<id>conjars</id>
<name>Concurrent Conjars repository</name>
<url>http://conjars.org/repo</url>
<layout>default</layout>
</repository>

The absence of the pom.xml on the default maven repository should only be a temporary issue but it took me some time to figure it out so that you can avoid it easily by addind a second repo that provides the missing file.
