Eric Milles commented on GROOVY-11731:
--------------------------------------
I don’t have the spec at hand, but FromString is supposed to be supplied a
single string that indicates the signature. So “Integer,Map<String,Object>” for
two params. Multiple option values indicate alternate signatures.

> Key: GROOVY-11731
> URL: https://issues.apache.org/jira/browse/GROOVY-11731
> Project: Groovy
> Issue Type: Bug
> Reporter: Sven
> Priority: Minor
>
> {code:java}
> @CompileStatic
> static void main(String[] args) {
> test({ int rowNumber, Map<String, Object> currentRow ->
> // This is a placeholder for the actual logic that would process each
> row.)
> println "Row number: $rowNumber"
> println "Current row: $currentRow"
> })
> }
> static void test(@ClosureParams(value = FromString, options = ["Integer",
> "Map<String, Object>"]) Closure closure) {
> int rowNumber = 0
> Map <String, Object> currentRow = [:]
> closure(rowNumber, currentRow)
> } {code}
> The above code works with groovy 3.0.18 and below after that it stops working
> I got it to work like that:
> {code:java}
> @CompileStatic
> static void main(String[] args) {
> test({ int rowNumber, Map<String, Object> currentRow ->
> // This is a placeholder for the actual logic that would process each
> row.)
> println "Row number: $rowNumber"
> println "Current row: $currentRow"
> })
> }
> static void test(@ClosureParams(value = FromString, options = ["Integer,
> Map<String, Object>"]) Closure closure) {
> int rowNumber = 0
> Map <String, Object> currentRow = [:]
> closure(rowNumber, currentRow)
> }
> {code}
> But either the doc is wrong or the implementation has a bug.
>
> The error I get is the following:
> Incorrect number of parameters. Expected 1 but found 2
> @ line 9, column 10.
> test({ int rowNumber, Map<String, Object> currentRow ->
> ^
