Custom deliverable - Examine index wrong LuceneIndexFolder

[giordanop]

What went wrong?

I'm writing a custom deliverable "rebuildindex", which rebuilds the Examine indexes.
This is the code snippet:

public override async Task<DeliverableResponse> Run(string command, string[] args)
{
      await Out.WriteLineAsync("rebuildindex START");
      ExamineManager.Instance.RebuildIndex();
      return DeliverableResponse.Continue;
}

So, quite simple.

What should have happened?

I would expect that indexes are correctly updated in their folder "\wwwroot\App_Data\TEMP\ExamineIndexes..." , but they are built in another folder: "\wwwroot\~\App_Data\TEMP\ExamineIndexes..."

Debugging, I see that the LuceneIndexFolder contains the wrong folder
(UmbracoExamine.UmbracoContentIndexer) ExamineManager.Instance.IndexProviderCollection[2]).LuceneIndexFolder contains "\wwwroot\~\App_Data\TEMP\ExamineIndexes\..."

How can I reproduce the issue?

1. I installed Chauffeur
2. I implemented a custom deliverable "rebuildIndex"
3. I ran Chauffeur with "rebuildIndex"
4. It creates a new folder structure under "\wwwroot\~\App_Data\TEMP\ExamineIndexes" and rebuilds indexes inside it
