Hi,

I tried running pub build, and it stopped before overwriting files. (In my case, I was running dart2js manually to test lazy loading, so my web/ dir had compiled files in it)

Pub build did the right thing, however it's a bit unclear what the error is. I'm wondering if developers new to Dart will understand how to take action. I'd like to propose a strawman for your consideration, in order to help new developers address the issue.

Actual:

Build error:
Transforms {Dart2JS on lazyloadtest|web/lazyloadtest.dart} all emitted asset lazyloadtest|web/lazyloadtest.dart.js.map.
Build error:
Transforms {Dart2JS on lazyloadtest|web/lazyloadtest.dart} all emitted asset lazyloadtest|web/lazyloadtest.dart.precompiled.js.
Build failed.

Can we add:

", but asset was also found on filesystem at [path]. Skipping transform to avoid overwriting file."

(just a strawman)

If you like the idea, I can submit the patch for your consideration. Suggestions for better message very welcome.

Thanks!

Seth, you've been filing a fair number of duplicate issues. This is the second time you've filed an issue for this, for example (see issue #783). Could you try to be more vigilant about searching for existing issues before filing new ones?

Apologies. You are correct, I should search for issues before filing them.
