Compilation error spark 2.2.3 and hadoop 2.7

Hi,

I am first time trying to use dr-elephant. Trying to compile on mac and failing with below:
Command is: play -Dhadoopversion=2.7.0 -Dsparkversion=2.2.3 -Dsbt.repository.config=app-conf/resolver.conf clean compile test
activator is ~/Development/Tools/activator-dist-1.3.12//bin/activator
[info] Loading global plugins from ~/.sbt/0.13/plugins
[info] Loading project definition from ~/Development/workspace/git/dr-elephant/dr-elephant/project
[error] ~/Development/workspace/git/dr-elephant/dr-elephant/project/Dependencies.scala:17: object Project is not a member of package play
[error] import play.Project._

[error] (compile:compile) Compilation failed

Appreciate any help.

Thanks,

Reproduce the reported command with the stated Spark 2.2.3 and Hadoop 2.7.0 versions, then inspect project/Dependencies.scala at the failing import and dependency declarations. Done means the project compiles and the test task completes without the reported errors.
