Building Spark using Maven requires Maven 3.0.4 or newer and Java 7+.

Building with build/mvn

Spark now comes packaged with a self-contained Maven installation to ease building and deployment of Spark from source located under the build/ directory. This script will automatically download and setup all necessary build requirements (Maven, Scala, and Zinc) locally within the build/ directory itself. It honors any mvn binary if present already, however, will pull down its own copy of Scala and Zinc regardless to ensure proper version requirements are met. build/mvn execution acts as a pass through to the mvn call allowing easy transition from previous build methods. As an example, one can build a version of Spark as follows:

{% highlight bash %} build/mvn -Pyarn -Phadoop-2.4 -Dhadoop.version=2.4.0 -DskipTests clean package {% endhighlight %}

Other build examples can be found below.

Note: When building on an encrypted filesystem (if your home directory is encrypted, for example), then the Spark build might fail with a "Filename too long" error. As a workaround, add the following in the configuration args of the scala-maven-plugin in the project pom.xml:

<arg>-Xmax-classfile-name</arg>
<arg>128</arg>

and in project/SparkBuild.scala add:
