Build fails with @nx/webpack:webpack executor when setting generatePackageJson to true about nx HOT 11 CLOSED

@SirPhemmiey i cannot provide the repo as it’s private.

But I had previously experienced this error message because I was not setting the webpack plugins outputPath in my project json

I can give you an example of a working config later

@dan-cooke can you provide the github project for us to compare? and what do you mean by "setting out path correctly">

from nx.

Hi,
Any update on this ?

from nx.

Hello, any update on this, please?

from nx.

I cannot reproduce this, I am using generate package successfully in my project. Check you guys are setting out path correctly

from nx.

@dan-cooke i would highly appreciate it, thank you.

Hi @dan-cooke , could you provide the configuration example you mentioned in your last comment?

from nx.

{
  "name": "api",
  "$schema": "../../node_modules/nx/schemas/project-schema.json",
  "sourceRoot": "apps/api/src",
  "projectType": "application",
  "targets": {
    "build": {
      "executor": "@nx/webpack:webpack",
      "options": {
        "webpackConfig": "apps/api/webpack.config.js",
        "outputPath": "dist/apps/api"
      }
    }
}

const { NxWebpackPlugin } = require('@nx/webpack');
const { join } = require('path');

module.exports = {
  output: {
    path: join(__dirname, '../../dist/apps/api'),
  },
  plugins: [
    new NxWebpackPlugin({
      target: 'node',
      compiler: 'tsc',
      main: './src/main.ts',
      tsConfig: './tsconfig.app.json',
      generatePackageJson: true,
      transformers: [
        {
          name: '@nestjs/swagger/plugin',
          options: {
            introspectComments: true,
          },
        },
      ],
      assets: ['./src/assets'],
      optimization: false,
      outputHashing: 'none',
    }),
  ],
};

Works for me

I can post a min repro someday soon, but have you made sure you are not running with the nx cache? I always run my builds with --skipNxCache because i've found it to be stale most of the time

Edit: Just realised im missing outputPath, I added that in and it still works

Hi @dan-cooke,
Thanks. Testing it...

from nx.

I'm not sure if this helps but I ran into this issue with an application that was using TSC that was importing a SWC library with a custom executor I wrote to generate the application's package json since it couldn't use esbuild or webpack.

My executor looked like this

   // The call to getHelperDependenciesFromProjectGraph was failing
    const helperDependencies = getHelperDependenciesFromProjectGraph(
        context.root,
        context.projectName!,
        context.projectGraph!
    );

    const packageJson = createPackageJson(context.projectName!, context.projectGraph!, {
        target: context.targetName,
        root: context.root,
        isProduction: true,
        helperDependencies: helperDependencies.map((dep) => dep.target),
    });

Removing the function call getHelperDependenciesFromProjectGraph and passing in an empty array for helperDependencies alleviated the issue for that application

This issue has been resolved and therefore I'm going to close it.

Thanks everyone for weighing in!
