------------------------------------

             Summary: no temp file cleanup in WagonFetcher after an error
                 Key: MINDEXER-94
                 URL: https://jira.codehaus.org/browse/MINDEXER-94
             Project: Maven Indexer
          Issue Type: Bug
    Affects Versions: 5.1.1
            Reporter: Tomas Stupka
            Priority: Minor
         Attachments: deleteTempFile.diff

see o.a.m.index.updater.WagonHelper.WagonFetcher.retrieve(name) in indexer.core 5.1.1

a temp file is created to store the remote index, but in case that the following retrieve( name, target ) call throws an exception, then no attempt is made to remove this file. 

Also that the temp folder might become polluted after a while - e.g in a scenario like we have encountered in NetBeans - see also https://netbeans.org/bugzilla/show_bug.cgi?id=246409

see also attached fix suggestion ...
