Repro for issue importing json module across project boundary in Yarn monorepo (incremental compilation)

This repo is a minimal case that exhibits the following traits:

• It is a Yarn monorepo with two packages:

  • packages/main, this one imports a JSON file from:
  • packages/strings

Each package is its own TypeScript project, and takes advantage of TypeScript incremental compilation.

In order to see

• Run yarn to install typescript

• yarn repro to reproduce the issue. This runs the following commands:

  1. yarn clean - removes all build artifacts
  2. yarn build - the first build succeeds
  3. yarn build - the second one fails!

Note that the packages/main/tsconfig.json project has packages/strings/tsconfig.json listed as a reference; however, tsc still complains that the main project doesn't have foo.json in its project file list.

> yarn repro
yarn run v1.16.0
$ yarn run clean && yarn run build && yarn run build
$ find . -iname 'lib' -type d | grep -v node_modules | xargs rm -rf
$ tsc --build .
$ tsc --build .
error TS6307: File '<project-dir>/packages/strings/lib/foo.json' is not in project file list. Projects must list all files or use an 'include' pattern.
