Description

I created a new project with “create-react-native-app” and then ejected it to plain react native project. When i try to run “react-native run-android” command i get build failed with error Execution failed for task ‘:app:compileDebugJavaWithJavac’.

Reproducible Demo

I executed following commands. create-react-native-project [projectname] cd [projectname] npm run eject react-native run-android

The result output is as follows.
