Yes, it doesn't really hurt anything except to be confusing cruft that has 
a tendency to accumulate in POMs. If we're going to put those lines back, I 
suggest that they be accompanied by a comment that they are known to be a 
useful assist for certain versions of IntelliJ and are not needed for the 
correctness of the build itself.

Sure, it really doesn't hurt, because we already define and maintain 
`${java.version}` anyway. It's two lines of standard config that were already 
there. This is truly not an issue.

Maven is the build of reference, true; but maven itself doesn't need the 
JDK version to be specified both in the scala plugin configuration and in the 
compiler plugin configuration. While I understand that IntelliJ is used by many 
Spark developers, it isn't some sort of officially preferred IDE of reference. 
That's why I have some qualms about embedding workarounds into our POM just to 
satisfy the idiosyncrasies of a particular IDE.

The Maven build is the build of reference, and we rely on IDEs to parse the 
details of the build from the pom.xml file. So it's right for the IDE to need 
to find information like JDK level (among a hundred other things) in the POM 
file. The `maven-compiler-plugin` is a standard built-in plugin whose config it 
consults to figure this out. It's not at all a hack. At least: we've always had 
this (and other superfluous config) for the compiler plugin in the build. This 
just cropped up because we trimmed it, and trimmed two lines too far.

Hmmm... that's arguably broken behavior on the part of IntelliJ or 
something to be worked around in IntelliJ configuration, not by hacking our 
POM. Without the POM hack, though, it is definitely something that deserves 
explanation in the Building Spark docs.

These are maven-compiler-plugin configurations. We don't use 
maven-compiler-plugin to compile Java code:
