Apache Spark reassigned SPARK-13780:
------------------------------------
Assignee: (was: Apache Spark)
> SQL "incremental" build in maven is broken
> ------------------------------------------
>
> 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.
