simply change
outDir: process.cwd()
to
outDir: process.cwd() + '/build'
in get-options-overrides.ts would fix the problem

[ezolenko]

This is by design -- typescript refuses to overwrite input files by output files so you don't destroy all your source code :)

[grayflow]

@ezolenko , but TypeScript 2.9 support import json file as es6 module now

[grayflow]

may be it's a typescript bug microsoft/TypeScript#24715

[ezolenko]

nvm, I'll do a workaround -- it works as intended if you use tsc directly, but shouldn't trip the plugin up.

[ezolenko]

@grayflow I added your workaround, check if master works for you

[grayflow]

@ezolenko , it works

[grayflow]

@ezolenko , another problem: rollup-plugin-typescript2 would not respect mapRoot option in tsconfig.json

[ezolenko]

@grayflow I don't think I can respect mapRoot -- I'm not writing out maps myself, I give them to rollup and it meshes them with maps generated by other plugins on the chain and then generates its own mapping for the bundle. For example if you add uglify plugin, maps will go ts -> plain js -> uglified js -> bundled js (not sure about the order of the last two)
