Christopher Smith updated GROOVY-11276:
---------------------------------------
Description:
There's a chance this is a duplicate of a ticket recently fixed, but it's odd
enough (and the message is unclear enough) that I'm reposting it.
{code}
Map<String, List<String>> idsForAccounts(Collection<String> persons) {
Map<Object, Object> fromGraph = retrieve()
// workaround for buggy database implementation follows
new HashMap<String, List<String>>().tap { result ->
putAll(fromGraph as Map<String, List<String>>)
persons.forEach {
if (!result.containsKey(it)) {
result.put(it, emptyList())
}
}
}
}
{code}
{code}
[Static type checking] - Cannot find matching method
java.util.HashMap#put(java.lang.String, java.util.List<#T>). Please check if
the declared type is correct and if the method exists.
@ line 73, column 21.
result.put(it, emptyList())
^
{code}
Update: Using a type witness as {{Collections.<String> emptyList()}} works.
