Unused 'catch' parameter

Reports catch parameters that are unused in their corresponding blocks. This inspection will not report any catch parameters named "ignore" or "ignored".

Example:

try {
    def arr = new int[3]
    arr[5] = 5
} catch(Exception ex) {
    println('Catching the exception')
}

Here the parameter ex is never used in catch block.

After the quick-fix is applied:

try {
    def arr = new int[3]
    arr[5] = 5
} catch(Exception ignored) {
    println('Catching the exception')
}
