Build failed when `npx react-native run-android`

I ejected my expo project, followed the instruction for unimodules configuration and made the additional setup for packages mentioned by expo eject.

Now I have this when I npx react-native run-android:

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':unimodules-barcode-scanner-interface:compileDebugJavaWithJavac'.

I tried npm install unimodules-barcode-scanner-interface --save, then I get this error:

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':unimodules-camera-interface:compileDebugJavaWithJavac'.

The funny thing is if I do npm install unimodules-camera-interface, I come back to the earlier error and so on.

No one?

I solved it, you shouldn’t put a & in expo.name value from app.json
