Exception Guard – Detects hidden throw points in Kotlin, checks @throws docs/annotations and Java interop, helping you write safer, more predictable code.

⚡ Exception Guard

Exception Guard helps you write safer Kotlin code by detecting potential exceptions in your functions, methods, and classes.

Many apps crash unexpectedly because Kotlin does not enforce checked exceptions (unlike Java). This plugin makes those risks visible directly in the IDE, so you can handle them before they cause runtime errors.

✨ Features

  • 🔍 Kotlin - Java Function body checking
    Detects throw statements inside functions and highlights them as warnings.

  • 📖 Doc read
    If function KDoc contains @throws, a warning will be highlighted.

  • 🏷️ @Throws annotation checking
    Functions annotated with @Throws(...) will be detected and highlighted.

  • ☕ Java interop throws checking
    If a Java function declares throws, e.g.

    public void func() throws IllegalArgumentException { ... }

🚨 Why this plugin?

Kotlin does not support checked exceptions. This means developers often miss possible throws in code and documentation. As a result, many crashes happen silently and unpredictably.

Exception Guard ensures you are aware of every possible exception point in your codebase.
