webpack和CleanWebpackPlugin似乎在启动和每次保存时删除output.path而不是仅删除初始时间

Question

After updating to webpack 3.10.0 and clean-webpack-plugin to 2.0.1 then updating webpack.js config to use cleanOnceBeforeBuildPatterns . Output.path get cleaned up on every save instead of only once during initial run.

webpack.js

output: {
    filename: 'js/[name].bundle.js',
    path: path.resolve(__dirname, '..', '.tmp', 'public')
  },
...
plugins: [
    new ExtractTextPlugin('styles/[name].bundle.css'),

    new CleanWebpackPlugin({
      cleanOnceBeforeBuildPatterns: [path.resolve(__dirname, '..', '.tmp')],
      verbose: true,
      dry: false
    }),

I wonder, it doesnt like path.resolve?

Answer 1

I have reached out to the extension author, and the simple fix was to add folders to .tmp dir to ignore.

new CleanWebpackPlugin({
      cleanOnceBeforeBuildPatterns: [path.resolve(__dirname, '..', '.tmp')],
      cleanAfterEveryBuildPatterns: ['!images/**/*', '!fonts/**/*'],
      verbose: true,
      dry: false
    })
