Description

It looks like the nightly Maven snapshots broke after we set JAVA_7_HOME in the build: https://amplab.cs.berkeley.edu/jenkins/view/Spark%20Packaging/job/spark-master-maven-snapshots/1573/. It seems that passing -javabootclasspath to scalac using scala-maven-plugin ends up preventing the Scala library classes from being added to scalac's internal class path, causing compilation errors while building doc-jars.

There might be a principled fix to this inside of the scala-maven-plugin itself, but for now I propose that we simply omit the -javabootclasspath option during Maven doc-jar generation.
