KT.PRINT_STACK_TRACE

Print the stacktrace of an exception

This rule reports code that tries to print the stacktrace of an exception. Instead of simply printing a stacktrace a better logging solution should be used.

Noncompliant Code

Copy

fun foo() {
    Thread.dumpStack()
}

fun bar() {
    try {
        // ...
    } catch (e: IOException) {
        e.printStackTrace()
    }
}

Compliant Code

Copy

val LOGGER = Logger.getLogger()

fun bar() {
    try {
        // ...
    } catch (e: IOException) {
        LOGGER.info(e)
    }
}
