tsc --build + specify tsconfig.json

Question

I want to run

tsc --build

But I want to have tsc use a different tsconfig.json file.

npx tsc --build --project tsconfig-abc.json

But I get this error

error TS5094: Compiler option '--project' may not be used with '--build'.

I've tried adding the build option to tsconfig but that doesn't seem to work?

  "buildOptions": {
    "build" : true
  },

Answer 1

The answer is simply to provide the file name at the end - no param name.

tsc --build tsconfig-simple.json
