React Native Error while trying to build android app

Question

I am getting errors while trying to build a React Native App. (I tried both using Expo, then ejecting to React Native + Starting React Native from scratch and trying to build it).

The problem is related to the file j2objc-annotations-1.1.jar, which apparently has Denied Access

The log says the following:

Also thanks for any help.

Error: Command failed: gradlew.bat app:installDebug -PreactNativeDevServerPort=8081

A problem occurred configuring root project 'MyAppName'.
> Could not resolve all artifacts for configuration ':classpath'.
   > Could not download j2objc-annotations.jar (com.google.j2objc:j2objc-annotations:1.1)
      > Could not get resource 'https://jcenter.bintray.com/com/google/j2objc/j2objc-annotations/1.1/j2objc-annotations-1.1.jar'.

Answer 1

I found the solution.

Delete the file --> in this case j2objc-annotations-1.1.jar from the folder in the error.

Run the build android command again and it will work correctly
