ScriptRunner script "Cannot find matching method" Transition

[Jevgenija K]

Hi! 

I'm sorry in advance if I sound like don't knw what I'm talking about. That's because I don't.

We've got 3 listener scripts set up, that copy issues from Service Desk to Core and sync all the info between the issues, including status, field updates and comments. At some point not long ago the script that synchronizes statuses stopped working.

We first thought that it cold be due to the fact that we've added some new events. We've updated the event list for the listener to include the new events. Apon investigating further we've discovered that there are two errors in the code: 

[Static type checking] - Cannot find matching method Transition#<init>(int,java.lang.Strng).

Here's the code

def transitionIssue(Issue issue, String value) {

if (value.equals(issue.getStatusId())) {
return;
}
WorkflowManager workflowManager = ComponentAccessor.getWorkflowManager();
IssueService issueService = ComponentAccessor.getIssueService()
// JiraAuthenticationContext jiraAuthenticationContext = ComponentAccessor.getJiraAuthenticationContext();
// ApplicationUser currentUser = jiraAuthenticationContext.getLoggedInUser();

try {

// jiraAuthenticationContext.setLoggedInUser(user);
String fromStatusId = issue.getStatus().getId();
//log.debug("Transitioning issue from " + issue.getStatus().getName() + "-" + fromStatusId + " to " + value);
JiraWorkflow workflow = workflowManager.getWorkflow(issue);
Map<String, Set<Transition>> transitionMap = new HashMap<>();
for (ActionDescriptor action : workflow.getAllActions()){
String statusToId = workflowManager.getNextStatusIdForAction(issue, action.getId());
//log.error("Action with id " +action.getId() + " leads to status " + statusToId);
if (!fromStatusId.equals(statusToId)) {
Transition transition = new Transition(action.getId(), statusToId);
for (StepDescriptor step: workflow.getStepsForTransition(action)){
transitionMap.compute((String) step.getMetaAttributes().get("jira.status.id"), new BiFunction<String, Set<Transition>, Set<Transition>>() {
@Override
public Set<Transition> apply(String k, Set<Transition> v) {
Set<Transition> transitionSet = v == null ? new HashSet<>() : v;
transitionSet.add(transition);
return transitionSet;
}
})
};
}
else {
log.error("The transition leads to itself");
}
};

and

[Static type checking] - Cannot call Script30#findPath(java.util.Map <java.lang.String,  java.util.Set>, java.util.Set < java.lang.String>, java.lang.String, java.lang.String) with arguments [java.util.Map<String, Set>, java.util.Set ,T extends java.lang.Object>, java.lan.String, java.land.String]

Code:

def Optional<List<Integer>> findPath(Map<String, Set<Transition>> transitionMap,
String statusFromId, String statusToId) {

return findPath(transitionMap, Collections.emptySet(), statusFromId, statusToId);
}

def Optional<List<Integer>> findPath(Map<String, Set<Transition>> transitionMap, Set<String> visited,
String statusFromId, String statusToId) {
List<Integer> shortestPath = null;
Set<Transition> transitions = transitionMap.get(statusFromId);
if (transitions == null) {
return Optional.empty();
} else {
Set<String> visitedPrime = new HashSet<>(visited);
visitedPrime.add(statusFromId);
for (Transition transition : transitions) {
if (transition.statusToId.equals(statusToId)) {
return Optional.of(Collections.singletonList(transition.actionId));
} else if (!visited.contains(transition.statusToId)) {
Optional<List<Integer>> path = findPath(transitionMap, visitedPrime, transition.statusToId, statusToId);
if (path.isPresent() && (shortestPath == null || shortestPath.size() - 1 > path.get().size())) {
shortestPath = new ArrayList<>();
shortestPath.add(transition.actionId);
shortestPath.addAll(path.get());
}
}
}
}
return Optional.ofNullable(shortestPath);
}

 Thank you in advance for any help!

This looks more like a syntax error where it can't find the method you used which I suspect the culprit is this line: 

Transition transition = new Transition(action.getId(), statusToId);

 You are declaring the Transition with some invalid constructor. Not sure if this is your full code, but I don't see this variable was being used elsewhere.

Thank you very much for the answer! My initial post did not contain the whole code, it's a rather long string. I'll post it here so that there is no confusion. What baffles me in this whole sitauation is that the listenere worked fine for three months and nobody made any changes in the code before the problem accured.

Your Transition class constructor has been set to private, causing it to not accessible. 

private Transition(int actionId, String statusToId) {
    this.actionId = actionId;
    this.statusToId = statusToId;
}

Please remove the private and try again.

Thank you very much for your help! This solved one error, but the other one persists and the listener still does not sync the issue statuses, unfortunetly. 

This is the error:

[Static type checking] - Cannot call Script30#findPath(java.util.Map <java.lang.String,  java.util.Set>, java.util.Set < java.lang.String>, java.lang.String, java.lang.String) with arguments [java.util.Map<String, Set>, java.util.Set ,T extends java.lang.Object>, java.lan.String, java.lang.String]

and this is the line of code, where the error pops (line 134, column 16): 

return findPath(transitionMap, Collections.emptySet(), statusFromId, statusToId);
