DataHub

1.The following issue happened.  Should I install scala manually?  Or the command " ./gradlew build"  will install it automatically?

```Execution failed for task ':datahub-frontend:compileScala'.
&gt; Compilation failed```
2.  After I install scala manually,  it apprears  the following info:

```[Error] /datahub/datahub-frontend/build/src/play/routes/router/Routes.scala:23: type CentralLogoutController is not a member of package controllers
[Error] /datahub/datahub-frontend/build/src/play/routes/router/Routes.scala:27: type TrackingController is not a member of package controllers
[Error] /datahub/datahub-frontend/build/src/play/routes/router/Routes.scala:40: type CentralLogoutController is not a member of package controllers
[Error] /datahub/datahub-frontend/build/src/play/routes/router/Routes.scala:44: type TrackingController is not a member of package controllers```

hey! could you show the whole output when you get this error above:
```Execution failed for task ':datahub-frontend:compileScala'.
&gt; Compilation failed```
