== Why is this an issue? Having all branches of a `match` or `if` chain with the same implementation indicates a problem. In the following code: [source,scala] ---- if (b == 0) { // Noncompliant doSomething } else { doSomething } i match { // Noncompliant case 1 => doSomething case 2 => doSomething case 3 => doSomething case _ => doSomething } ---- Either there is a copy-paste error that needs fixing or an unnecessary `match` or `if` chain that needs removing. === Exceptions This rule does not apply to `if` chains without `else`, nor to `match` without a `case _` alternative. [source,scala] ---- if (b == 0) { doSomething } else if (b == 1) { doSomething } ---- ifdef::env-github,rspecator-view[] ''' == Implementation Specification (visible only on this page) include::../message.adoc[] include::../highlighting.adoc[] ''' == Comments And Links (visible only on this page) include::../comments-and-links.adoc[] endif::env-github,rspecator-view[]
