Jira 7 -> 8 componentmanager problem

[Csaba Horváth]

Hello All,

Please help me, we've just upgraded from Jira 7 to Jira 8.

1 of our scripts failed. ComponentManager no longer usable. Could you help me how can I revive the script?

ChangeHistoryManager changeHistoryManager = (ChangeHistoryManager)ComponentManager.getComponentInstanceOfType(ChangeHistoryManager.class);

The error message: [Static type checking] - The variable [ComponentManager] is undeclared.

Thank you!

The full script

List changeHistory = changeHistoryManager.getChangeHistories(issue);
for (int i = changeHistory.size() - 1; i >= 0; i--)
{
ChangeHistory changeHistoryItem = (ChangeHistory)changeHistory.get(i);

List changeItemBeans = changeHistoryItem.getChangeItems();
Iterator it = changeItemBeans.iterator();
while (it.hasNext())
{
GenericValue change = (GenericValue)it.next();
String changedField = change.getString("field");
if (changedField.equalsIgnoreCase("status"))
{
String oldStatus = change.getString("oldstring");
return oldStatus;
}
}
}
return null;

Some Details to above:

ComponentManager has been deprecated since JIRA 7.11, which is the reason that you cannot resolve this class any longer.

You should migrate to using ComponentAccessor instead-> https://docs.atlassian.com/software/jira/docs/api/7.11.0/com/atlassian/jira/component/ComponentAccessor.html

getComponent and  getComponentByType are two key methods to load components of a specific type. Sample code is below:

Old Code:

RemoteIssueLinkService remoteIssueLinkService = ComponentManager.getComponentInstanceOfType(RemoteIssueLinkService.class)

RemoteIssueLinkService.RemoteIssueLinkListResult links = remoteIssueLinkService.getRemoteIssueLinksForIssue(currentUser, issue)

New Code:

ComponentAccessor.getComponentOfType(RemoteIssueLinkService.class).getRemoteIssueLinksForIssue(currentUser, issue);
