Mill version 0.11.0 Compilation Error

[shawnz99]

Describe the bug When compiling vizier with mill version 0.11.0 using command mill vizier.compile it returns the following errors

[build.sc] [41/49] compile 
[info] compiling 1 Scala source to /home/shawnz99/src/school/research/vizier/vizier-scala/out/mill-build/compile.dest/classes ...
[error] /home/shawnz99/src/school/research/vizier/vizier-scala/build.sc:10:8: object Ctx is not a member of package mill.util

[error]                         ^
[error] three errors found
1 targets failed
compile Compilation failed

However when compiling with mill version 0.10.10 it compiles fine with no errors

To Reproduce Steps to reproduce the behavior:

1. Clone vizier
2. Make a branch off of the v2.0 branch
3. Install mill and ammonite (initially installed mill using coursier, then to revert the version easier I used a curl'd version of mill)
4. compile vizier using the command mill vizier.compile
5. See error

Expected behavior Expected to compile with no errors
