Hi Anna,

Thank you for the patch, it makes the contribution much easier!
I will continue my review tomorrow, I just wanted to post the findings from today.

1) The gradle wrapper script does not find the gradle-wrapper.jar, can you please add it to
the patch as well (https://docs.gradle.org/current/dsl/org.gradle.api.tasks.wrapper.Wrapper.html)?
2) Once the gradle-wrapper.jar is present the ./gradlew test runs successfully
3) The project can be imported to IntelliJ without any problems
4) I think a couple of more items should be added to .gitignore
   .gradle/ -> I think this is generated by the gradle wrapper
   out/ -> I am not sure why but when I import the project to IntelliJ and run a test from
there it generates the out folder which was not present with the ant build
5) Can we define the sourceCompatibility in build.gradle to say that we support 1.7 currently?
6) I have executed the package target with both ant and gradle and I found some differences,
can you please check that these are expected?
   In case of gradle build bat files are also generated for sqoop tools scripts.
   The .gradle folder is copied to build/sqoop-1.5.0-SNAPSHOT.bin__hadoop-2.6.0, I am not
sure this is desired.
   Some library versions are different in case of ant and gradle build.

I am posting the relevant lines from the diff output:
