Is % compile necessary for sbt example in README?

[wuservices]

The README has this example for including scaffeine with sbt:

"com.github.blemale" %% "scaffeine" % "3.1.0" % "compile"

Sorry this may be a silly question, but I was wondering what % "compile" did here. Does it do anything different than leaving it out?

Hello @wuservices !

You can leave it out as the compile configuration is the default one in SBT. However if you need the dependency only for your test, you will need to add the % "test" at the end.

If you need more details on how dependencies work in SBT you can look at the official documentation:
