(copy plugin) Error: ENOENT: no such file or directory, chmod <filename>

[HanMoeHtet]

Why is it throwing ENOENT when a file in dist does not exist? Isn't the purpose of this plugin to copy files into dist? The action is not even predictable. It only happens sometimes. However, files are indeed copied into dist but in CI, it always fails because of exit code 1.

Happening to me as well. Any ideas for a workaround?
In my case, I'm copying JSON localization files over to the dist folder after a build.

@gunnartorfis I just copied the source and tweaked a little. Just added try catch block Here

Same here. For some reason it fails to chmod a copied file.

And for me it fails sporadically, without any pattern, which suggests a race condition.

I have "rollup-plugin-copy": "3.4.0"

are you by chance using del, or any plugin that cleans the output directory? I started seeing the error when I added that. One solution would be to ensure that copy runs after del, and that both use the same buildEnd hook:

    del({
      targets: ['./.dist', './public'],
      hook: 'buildEnd',
      runOnce: true
    }),
    copy({
      targets: [{ src: 'prebuilt/*', dest: 'public/' }],
      hook: 'writeBundle',
      copyOnce: true
    })

If that doesn't work, fork the package and add:

if (!fs.existsSync(path.dirname(dest))) {
    fs.mkdirSync(path.dirname(dest), { recursive: true });
}

before the copy, to ensure that the directory is created before attempting to copy it. Fyi, that should solve any issues with this package.

Can someone provide a reproduction repo? I'll try to find the underlying reason 🙌

[DanielOrtel]

I can provide one, though I'm currently using the fork I created(see the linked PR above), and I haven't seen this issue since.

Basically add this to any package's rollup config:

const del = require('rollup-plugin-delete');

export const config = {
    input: './index.js',
    output: {
      sourcemap: true,
      dir: './.dist',
      format: 'esm'
    },
      copy({
        targets: [{ src: 'prebuilt/*', dest: 'public/' }],
        copyOnce: true
      }),
      del({
        targets: ['./.dist', './public'],
        hook: 'buildEnd',
        runOnce: true
      })
}

And ensure there is something in the prebuilt folder to copy. I believe it should fail, because the folder does not exist, since the del hook removed it.

If you need a full repro, I can also provide a repo for that, though again, #71 fixes this issue for me.

@DanielOrtel thank you, will try locally
