When trying to build datahub, gradle hangs here:

<====---------> 34% EXECUTING [1h 20m 42s]
> :datahub-web:emberWorkspaceTest
> :datahub-frontend:compilePlayBinaryScala

This happens on OSX as well as on Linux. Any idea how this can be resolved?

What command did you run? Could you share more logs?

you should run the cradle build with --stacktrace -> I ran with stack trace and found out that it needs java 8 + path set

Thanks - builds now; I was probably missing Chrome.
