Apache Maven is a Java-based build tool that works with both Java and Scala source code. It employs a "convention over configuration" philosophy that attempts to make useful assumptions about project structure andcommon build tasks in order to reduce the amount of explicit configuration by a developer. Although it has faced some criticismfor its us...
Maven defines a standard convention for the directory structure of a project. The downloaded Sparkour example contains the following important paths and files: 1. pom-java.xml: A Maven file for Java projects containing managed library dependencies. 2. pom-java-local.xml: A Maven file for Java projects containing unmanaged library dependencies that ...
Managed Library Dependencies
A key feature of Maven is the ability to download library dependencies when needed, without requiring them to be a local part of yourproject. In addition to Apache Spark, we also need to add the Scala library (for the Scala example only) and Commons CSV (for both Javaand Scala): If you don't know the groupID or artifactID of your dependency, you can probably find them on that dependency's website or in the Maven Central Repository. 1. Let's build our example source code with Maven. 2. The pac...
Unmanaged Library Dependencies
An alternative to letting Maven handle your dependencies is to download them locally yourself. We can usethe addjars-maven-pluginplugin to identify a local directory containing theseunmanaged libraries. 1. The plugin is defined in the pom-java-local.xml and pom-scala-local.xml POM files. This plugin works with both Java and Scala code. Our examples specify the lib/directory for storing extra libraries. 2. Next, manually download the Commons CSV library into the lib/directory. 3. Build the cod...
As the number of library dependencies increases, the network overhead of sending all of those files to each node in the Spark cluster increases as well. The officialSpark documentation recommends creating a special JAR file containing both the application and all of its dependencies called an assembly JAR(or "uber" JAR) to reduce network churn. The...

SBT has specific, built-in support for one specific kind of cross-building, but that's all; if you look at projects that have to cross-build across any other axis than Scala version (e.g. multiple versions of akka, multiple versions of scalaz-stream, cats/scalaz variants) then their build definitions are just as awful and complex as any project ...
