Description

In sbt-dotty/sbt-test, some incremental compilation tests ported from Zinc are marked as disabled. The reason is that we are missing some sbt tasks such as:

  • checkRecompilations
  • checkClasses
  • checkDependencies
  • check-products

An example on how to implement these tasks for Dotty can be found here. Zinc reference implementation can be found here.

Research direction
The issue requires implementing missing sbt tasks (checkRecompilations, checkClasses, checkDependencies, check products) to enable ported incremental compilation tests from Zinc. Start by examining the example build.sbt at lampepfl/dotty/sbt dotty/sbt test/source dependencies/abstract type override/build.sbt and the Zinc reference implementation at sbt/zinc/blob/9e72547df74ca72e9305a05f20740d5e19f0b590/internal/zinc scripted/src/test/scala/sbt/internal/inc/IncHandler.scala. Each task should be implemented following the patterns in those files. There are no assignees or comments, so the issue is available for work.
