From 0bbcafc672cf7f2a73d4363b0324f7990ed53f4f Mon Sep 17 00:00:00 2001 From: Jamie Thompson Date: Sat, 1 Feb 2025 11:36:40 +0100 Subject: [PATCH] build.mill files compiled by Scala 3 (#3369) This is work in progress to fix https://github.com/com-lihaoyi/mill/issues/3152 Numerous fixes were also needed to com-lihaoyi/mainargs, com-lihaoyi/sourcecode, and com-lihaoyi/mill-moduledefs With the current state, only 1 example/integration tests is still failing: - `integration.feature[plugin-classpath].local` known TODOs: - [x] Discover macro - [x] Applicative macro - [x] Caller macro - [x] Cross.Factory macro - [x] EnclosingClass macro - [x] Task macros - [x] Cacher macro - [x] Moduledefs compiler plugin (override inferrence) - [x] All core Mill modules compile with Scala 3.5.0 - [x] Fix Zinc reporter patch linenumbers of build scripts - [x] Check that bytecode analyzers work with Scala 3 - [x] cleanup library dependency conflicts - [x] Support new Scala 3 syntax in build.sc files - [x] ~Fix BSP reporter linenumbers for build scripts~ (Zinc reporter forwards to bsp) - [ ] Cleanup compiler warnings for outdated syntax known incompatibilities: - [ ] can't use `ExplicitResultTypes` scalafix rule - need to upgrade mill-scalafix - [x] ~`Cross.scala` uses the new quoted type syntax which scalafmt crashes on, (and version is frozen) so skip the file~ upgraded Scalafmt so not skipped anymore - [ ] skipping Mima currently due to 1000s of errors (perhaps we should generate filters?) - [ ] filtered one flaky test from `example.thirdparty[mockito]` - [ ] filtered out `integration.feature[plugin-classpath]` due to third party plugin dep --------- Co-authored-by: Li Haoyi --- .gitignore | 1 + .scalafix-3.conf | 5 + .scalafmt.conf | 4 +-
