Build error

[AviFix]

Hi,

I'm using macOS High Sierra.

I get this error when trying to build the project:

:: retrieving :: org.scala-sbt#boot-scala confs: [default] 4 artifacts copied, 0 already retrieved (20090kB/35ms) error: error while loading Class, class file '/var/root/.sbt/0.13/java9-rt-ext-oracle_corporation_9_0_1/rt.jar(java/lang/Class.class)' is broken (bad constant pool tag 18 at byte 216) [error] java.util.NoSuchElementException: head of empty list [error] Use 'last' for the full log. Project loading failed: (r)etry, (q)uit, (l)ast, or (i)gnore?

Thanks
Avi
