>                 Key: SPARK-13780
>                 URL: https://issues.apache.org/jira/browse/SPARK-13780
>             Project: Spark
>          Issue Type: Bug
>          Components: Build, SQL
>            Reporter: Marcelo Vanzin
>            Priority: Minor
>
> If you build Spark, and later try to build just the SQL module like this:
> {code}
> mvn ... -pl :spark-sql_2.11
> {code}
> You end up with a nasty error:
> {noformat}
> [error] uncaught exception during compilation: scala.reflect.internal.Types$TypeError
> scala.reflect.internal.Types$TypeError: bad symbolic reference. A signature in WebUI.class refers to term servlet
> in value org.jetty which is not available.
> It may be completely missing from the current classpath, or the version on
> {noformat}
> This is because of bad interaction between shading, Scala's signature field, and internal APIs exposing shaded classes.
> The fix is simple, we just need to add an explicit dependency on the jetty artifacts to the sql module.
