[Packager] Source Map not correctly referenced from JS bundle.

[qbig]

If I do the following bundle command, specifying the sourcemap file to be "index.android.map"

react-native bundle --platform android --dev false --entry-file index.android.js   --bundle-output android/app/src/main/assets/index.android.bundle   --assets-dest android/app/src/main/res/ --sourcemap-output android/app/src/main/assets/index.android.map

but in the output bundle file, 'bundle.js‘ is used as the sourceMappingURL

//# sourceMappingURL=bundle.js

If sourceMappingURL is the reference to the sourcemap file, shouldn't be "index.android.map" instead ? Or is 'bundle.js' use somewhere else internally?

@qbig can you try this with master and let me know the results?

I tried this, where "/Users/qiaoliang89/Downloads/myRn/react-native" is my clone from the repo.

node /Users/qiaoliang89/Downloads/myRn/react-native/local-cli/cli.js  bundle --platform android --dev false --entry-file index.android.js   --bundle-output index.android.bundle   --assets-dest /android/app/src/main/res/ --sourcemap-output index.android.map

but got

/Users/qiaoliang89/Downloads/myRn/react-native/node_modules/babel-core/lib/transformation/file/options/option-manager.js:181
          throw new ReferenceError(messages.get("pluginUnknown", plugin, loc, i));
          ^

might be #5135 ?

[qbig]

fixed with #5288. Can close.
