+**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:
+
+ scalacOptions in Compile ++= Seq("-Xmax-classfile-name", "128"),
+
+to the `sharedSettings` val. See also [this PR](https://github.com/apache/spark/pull/2883/files) if you are unsure of where to add these lines.
