"error: ')' expected but eof found." after Scala 2.12.13 #12317
Description
reproduction steps
Locally build sbt using Scala 2.12.13 and run:
lazy val root = (project in file("."))
lazy val sub1 = (project in file("sub1"))
lazy val sub2 = (project in file("sub2"))
lazy val sub3 = (project in file("sub3"))Partest for this is https://gist.github.com/eed3si9n/5cb9572eac9f2be11ae3a42cd25174ec
problem
This causes
/private/tmp/hello/build.sbt:24: error: ')' expected but eof found.
lazy val sub2 = (project in file("sub2")
^expectation
No error.
notes
The relevant place in sbt code is https://github.com/sbt/sbt/blob/4b71de0098b1f28b3d8ec6fa93e87cc5c9d50809/main-actions/src/main/scala/sbt/compiler/Eval.scala#L401-L408. It's possible I messed some other thing while upgrading to Scala 2.12.13, but figured I'd report this in case this pops up in a different way elsewhere.
