Questions about the configuration of source.exclude.

[zhangziyang960]

In my project, there is an old dependency whose source code is placed in the root directory's static folder. I use the output.copy configuration to copy it to the build output.

    copy: [
      {
        from: resolve('./static'),
        to: resolve('./dist/static')
      }
    ],

However, during the build process, I encountered an error because some of the code in this old dependency cannot be parsed by Node.js version 20.

× JavaScript parsing error: Expected ident

error   Failed to build.
error   Rspack build failed!

To address this, I tried using the source.exclude configuration to exclude the modules in the static folder from being parsed. But it didn't work.

exclude:[path.resolve(__dirname, 'static')],

Why is that?
Here is my complete configuration:

const path = require('path');
import { defineConfig, loadEnv } from '@rsbuild/core';
import { pluginVue2 } from '@rsbuild/plugin-vue2';
import { pluginLess } from '@rsbuild/plugin-less';

import { pluginBasicSsl } from '@rsbuild/plugin-basic-ssl';
const { RsdoctorRspackPlugin } = require('@rsdoctor/rspack-plugin');
const { publicVars: vueEnvs } = loadEnv({ prefixes: ['VUE_APP_'] });
const resolve = dir => {
  return path.join(__dirname, dir);
};
export default defineConfig({
  plugins: [
    pluginVue2({
      splitChunks: {
        vue: true,
        router: true
      }
    }),
    pluginLess({
      lessLoaderOptions: {
        lessOptions: {
          // additionalData: `@import "@/styles/less/variables.less`
          globalVars: {
            'primary-color': '#0096f7',
            'boder-color': '#dfdfdf',
            'warning-color': '#ffcc00'
          }
        }
      }
    }),
    pluginVue2Jsx(),
    pluginBabel(),
    pluginBasicSsl()
  ],
  server: {
    ...
    },
    client: {
      overlay: false

  },

      ...vueEnvs
    },
    exclude:[path.resolve(__dirname, 'static')],

    ],

      root: 'dist'
    }
  },
  tools: {
    bundlerChain: (chain, { CHAIN_ID }) => {
      if(process.env.RSDOCTOR ){
        chain.plugin('Rsdoctor').use(RsdoctorRspackPlugin, [
          {
            // 插件选项
            disableClientServer: false,
            features: ['lite', 'loader', 'plugins', 'bundle'],
          },
        ]);
      }
    },
  },

});

source.exclude is used to exclude modules transformed by swc-loader. It does not affect the parsing of Rspack's copy plugin.

Can you share the code that cannot be parsed?
