[Bug?] hash not stable with same files

[indooorsman]

see attachment. hash changes every build without any file changed. It may be a bug or by design or I missed some configuration？

esbuild.build({
  entryPoints: [entry],
  inject: ['./plugins/react-shim.js'],
  write: true,
  bundle: true,
  minify: false,
  watch: false,
  define: {
    APP_ADVERTISING_VERSION: JSON.stringify({
      version: packageJson.version,
      sparkUIVersion: packageJson.dependencies['spark-ui'],
      buildAt: new Date().toString(),
      buildPlatform: process.platform,
      env: mode
    })
  },
  outdir,
  target: ['chrome80', 'firefox78'],
  sourcemap: 'external',
  splitting: false,
  chunkNames: '[name]-[hash]',
  entryNames: '[name]-[hash]',
  assetNames: '[name]-[hash]',
  publicPath: '/static/advertising',
  logLevel: 'info',
  metafile: false,
  plugins: [aliasPlugin(alias), CssModulesPlugin({ v2: true })],
  loader: {
    '.svg': 'dataurl',
    '.png': 'file'
  }
});

I can take a look if you can provide self-contained sample code that reproduces the issue. It could potentially be an esbuild bug. Also make sure that the file contents and file paths (including virtual files generated by plugins) are the same between builds.

@evanw oh that's it... my plugin generate virtual files in random path ... 😭
