Duplicate error message (esp. when `pretty: true`)

[kitsonk]

What happens and why it is wrong

Duplicate semantic errors get logged to the console, which causes confusion. For example:

./node_modules/rollup/bin/rollup -c ../../rollup.config.js -i ../../js/main.ts -o gen/bundle/main.js --silent
[!] (rpt2 plugin) Error: ../../js/main.ts:8:1 - error TS2304: Cannot find name 'confounded'.

8 confounded;
  ~~~~~~~~~~

../../js/main.ts
Error: ../../js/main.ts:8:1 - error TS2304: Cannot find name 'confounded'.

8 confounded;
  ~~~~~~~~~~

I am not entirely sure how much this is rollup-plugin-typescript2 and how much of this is just the way rollup behaves, but I couldn't find an answer either way.

Versions

• typescript: 3.0.1
• rollup: 0.63.2
• rollup-plugin-typescript2: 0.16.1

any input on this ? I am also facing this issue

I don't get it with just any error, could you create a test repo with reproduction?

Might depend on error type (typescript only, or something that would trip rollup itself) execution mode (clean build / rebuild / watch) and rollup/plugin settings.

This is what I usually get:
(3 there were errors or warnings lines for 3 bundles that are generated in that build)

rpt2: there were errors or warnings.
rpt2: rolling caches
rpt2: there were errors or warnings.
rpt2: rolling caches
rpt2: there were errors or warnings.
rpt2: rolling caches
(!) Plugin rpt2: src/index.ts:316:18 - error TS2304: Cannot find name 'Plugin5Context'.

Going to close this out as a reproduction was unsuccessful and this issue has not received any activity in a few years (and may not be relevant in newer versions anymore).

Can re-open later if warranted on current versions and with a repro.
