This rule reports catch blocks for exceptions that have a type that is too generic. It should be preferred to catch specific exceptions to the case that is currently handled. If the scope of the caught exception is too broad it can lead to unintended exceptions being caught.

Noncompliant Code

fun foo() {
    try {
        // ... do some I/O
    } catch(e: Exception) { } // too generic exception caught here
}

Compliant Code

fun foo() {
    try {
        // ... do some I/O
    } catch(e: IOException) { }
}
