I’m using Mylyn and I have many Task in my Task List.
After upgrading from MyEclipse 2022 to 2023.01.01 (clean install), a popup is appearing after the workspace has loaded:

Problem occurred:
An internal error occurred during: “Task List Indexer”.
Could not load codec ‘Lucene60’. Did you forget to add lucene-backward-codecs.jar?

Has anyone an idea, how to solve this problem?

Thomas,

Thank you for the report – seems to be a bug in Mylyn we may have inadvertently picked up. We’re going to include a fix to this in an upcoming MyEclipse maintenance release. In the meanwhile, there are a couple of workarounds.

1) You could update to a newer version of Mylyn by installing it from this update site: https://download.eclipse.org/mylyn/updates/release/3.26.1
or
2) Delete the directory [workspace_location]/.metadata/.mylyn/.taskListIndex/ before starting MyEclipse. This will result in the Index being rebuilt and resolve the initial error you see. You will still see errors when you save / edit existing tasks or create new tasks, but I believe they are still persisted by the IDE.

Sorry for the inconvenience caused, thanks again for the report!

Thomas,

We’ve fixed this in 2023.1.2, do update to pick up the fix.

Thanks!
