groovy.lang.MissingMethodException：IssueLinkImpl而不是IssueLink

Question

In JIRA I try to change the issuetypelink to another linktype with the changeIssueLinkType function.

I get the following error:

groovy.lang.MissingMethodException: No signature of method: com.atlassian.jira.issue.link.DefaultIssueLinkManager.changeIssueLinkType() is applicable for argument types: (com.atlassian.jira.issue.link.IssueLinkImpl, com.atlassian.jira.issue.link.IssueLinkTypeImpl, com.atlassian.jira.user.DelegatingApplicationUser) values: [com.atlassian.jira.issue.link.IssueLinkImpl@fffff04e, com.atlassian.jira.issue.link.IssueLinkTypeImpl@ffe53fbd, ...] Possible solutions: changeIssueLinkType(com.atlassian.jira.issue.link.IssueLink, com.atlassian.jira.issue.link.IssueLinkType, com.atlassian.crowd.embedded.api.User)

I have no Idea how to fix it...

code:

    for (IssueLinkType linktype : issueLinkTypes) 
    {
        String name=linktype.getInward();
        if(name.equals("is parent of"))
        {
            linkTypeNew=linktype;
            break;
        }
    }

UserManager userManager = ComponentAccessor.getUserManager();
ApplicationUser sUser = userManager.getUserByKey("Username");

Collection<IssueLink> allIssueLinks =    ComponentAccessor.getIssueLinkManager().getIssueLinks(linkID);

for (Iterator<IssueLink> outIterator = allIssueLinks.iterator();    outIterator.hasNext();) {
         IssueLink issueLink = (IssueLink) outIterator.next();

        ComponentAccessor.getIssueLinkManager().changeIssueLinkType(issueLink,     linkTypeNew, sUser);
      }

Would be great if someone could help me:-/

Answer 1

Obviously your sUser variable is of wrong type. The method changeIssueLinkType() expects a user of type com.atlassian.crowd.embedded.api.User whereas you pass a user of type com.atlassian.jira.user.DelegatingApplicationUser .

I'm not a JIRA API expert, but as a quick fix I'd suggest the following:

import com.atlassian.crowd.embedded.api.User


ApplicationUser sUser = userManager.getUserByKey("Username")
User user = sUser as User // this line might fail!
....
ComponentAccessor.issueLinkManager.changeIssueLinkType issueLink, linkTypeNew, user

If the line fails, you have to create an instance of User on your own

Answer 2

Instead of passing in the sUser object (it implements ApplicationUser , which is not compatible with User ), you should call sUser.getDirectoryUser() and supply that result to your method call in order to get the correct user object type. You should also change the explicit ApplicationUser sUser = ... initialization to just def sUser = ... .

This works here because you have a DelegatingApplicationUser object which supports the getDirectoryUser method. If you have a different type of ApplicationUser implementation, which does not necessarily support that method, you would need to use a utility method to convert it. You can find more information on User vs ApplicationUser in Atlassian's documentation .
