Build failed with unrelated reasons to this PR:
```
[WARNING] Rule 0: org.apache.maven.plugins.enforcer.RequireFilesSize failed
with message:
The file drill-jdbc-all-1.12.0-SNAPSHOT.jar is outside the expected size
range.
This is likely due to you adding new dependencies to a
java-exec and not updating the excludes in this module. This is important as it
minimizes the size of the dependency of Drill application users.
/home/travis/build/apache/drill/exec/jdbc-all/target/drill-jdbc-all-1.12.0-SNAPSHOT.jar
size (31071836) too large. Max. is
