Daniel Abramowitz a3e25b23c6 Improve exception thrown when classes can't compile to be more clear (#33897)
Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/33897

Now the exception will display the class which caused the exception as well as helpful information as to why.

We've seen this happen a bunch due and have been very confused by the error message. It turns out that this processor runs before the classes listed are compiled. This means that if there's a compile error (or a missing import) the user will only see that this processor crashed, and not the compile error.

The additional information in the error is:

`java.lang.RuntimeException: Could not load classes set in ReactModuleList.nativeModules. Check that they exist and are imported correctly on class: com.meta.x.y.ReactPackage`

In this case,  `com.meta.x.y.ReactPackage` is the class which needs to be fixed. Before, the error message made no mention of this class or the annotation.

Changelog: [Internal] This will change the way the annotation processor crashes. It will throw a RuntimeException instead of a ClassCastException.

React Native brings React's declarative UI framework to iOS and Android. With React Native, you use native UI controls and have full access to the native platform.

  • Declarative. React makes it painless to create interactive UIs. Declarative views make your code more predictable and easier to debug.
  • Component-Based. Build encapsulated components that manage their state, then compose them to make complex UIs.
  • Developer Velocity. See local changes in seconds. Changes to JavaScript code can be live reloaded without rebuilding the native app.
  • Portability. Reuse code across iOS, Android, and other platforms.

React Native is developed and supported by many companies and individual core contributors. Find out more in our ecosystem overview.

📋 Requirements

React Native apps may target iOS 11.0 and Android 5.0 (API 21) or newer. You may use Windows, macOS, or Linux as your development operating system, though building and running iOS apps is limited to macOS. Tools like Expo can be used to work around this.

🎉 Building your first React Native app

Follow the Getting Started guide. The recommended way to install React Native depends on your project. Here you can find short guides for the most common scenarios:

📖 Documentation

The full documentation for React Native can be found on our website.

The React Native documentation discusses components, APIs, and topics that are specific to React Native. For further documentation on the React API that is shared between React Native and React DOM, refer to the React documentation.

The source for the React Native documentation and website is hosted on a separate repo, @facebook/react-native-website.

🚀 Upgrading

Upgrading to new versions of React Native may give you access to more APIs, views, developer tools, and other goodies. See the Upgrading Guide for instructions.

React Native releases are discussed in this discussion repo.
