Subject [jira] [Commented] (VFS-536) DefaultFileMonitor will ignore files forever if directory is deleted and recreated
Date Mon, 05 Jan 2015 19:37:34 GMT

    [ https://issues.apache.org/jira/browse/VFS-536?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14264973#comment-14264973

Sam Halliday commented on VFS-536:
----------------------------------

Damnit, I wasn't running the right code... I was running our current code with the workaround
when I tried this (local/published ivy confusion)

> We're using VFS2 in our emacs scala ide https://github.com/ensime/ensime-server
> Unfortunately, I've just discovered that if we watch a directory, e.g. here we are watching
the target directory for class files that are created by a compiler
>  https://github.com/ensime/ensime-server/blob/master/src/main/scala/org/ensime/indexer/FileWatchers.scala#L28
> then if the directory is deleted and recreated (as is done by the SBT scala build tool!)
then monitoring events are ignored forever!
> I can confirm that file watching works fine if individual files are added or removed.
