Thanks for the PR. Sorry for the bikeshedding below, but I looked way too long at this snippet trying to understand why there is a split.last.

Suggested change

	Seq(s"$millPath -i ${BSP.getClass.getCanonicalName.split("\\$").last}/start"),
	Seq(s"$millPath -i ${BSP.getClass.getCanonicalName.split("\\$").head}/start"),

Although, this is effectively an array of length 1 and both will give the same result, semantically, we want the first part of the split, not the last.

Good point

A run on my own Travis-CI account (https://travis-ci.org/github/lefou/mill/builds/740495671) gave the following error:

[info] Compiling 9 Scala sources to /home/travis/build/lefou/mill/out/bsp/compile/dest/classes ...
[error] /home/travis/build/lefou/mill/bsp/src/mill/bsp/BSP.scala:67:73: value first is not a member of Array[String]

Method .first isn't valid, but .head (my initial suggestion) is.

Lol, I don't know why I wrote first.
Corrected

Thanks!
