Inspectopedia Help

Condition of 'if' expression is constant

Reports if expressions that have true or false constant literal condition and can be simplified.

While occasionally intended, this construction is confusing and often the result of a typo or previous refactoring.


fun example() { if (true) { throw IllegalStateException("Unexpected state") } }

The quick-fix removes the if condition:

fun example() { throw IllegalStateException("Unexpected state") }
