Local variable is reassigned in closure or anonymous class

Last modified: 03 December 2024

Reports local variables assigned to expression with different type inside of closure or anonymous class.

Example:

int sum = 0
[1, 2, 3].each { sum += 'as' }
println(sum)

As a result, the integer variable sum is reassigned to a String expression.
