[IVYDE] eclipse file locking problem in ivy cache

[Marcel Wagner <ma...@gmx.de>]

We use in our projects a SNAPSHOT working model, so we publish a lot 
SNAPSHOT.jar files. Ivy supports this through checkmodified="true", to 
include also the date into its resolve strategy. On the command line, 
through ivy/ant all is fine. In eclipse there is a problem, the jars for 
each projects are in the cache directory, so all the projects locks the 
SNAPSHOT.jar. Now publishing a new SNAPSHOT.jar is useless in IvyDE, 
IvyDE can't replace the jar in the cache, it seems locked through other 
projects referencing the SNAPHOT.jar. ;-( So IvyDE should release all 
jars files in all projects classpath containers before making a resolve 
or the jars should retrieved in their own directory for each project 
like ivy is doing.

Regards,
Marcel

Marcel:
   I'm personally pretty sure that the jars are locked by Eclipse and  
not so much by Ivy.  If you're using Windows, you can use a  
downloadable utility called Unlocker to, well, unlock the jars.   
After you've done this, however, Eclipse will probably throw  
innumerable errors until you throw your hands up in despair and/or  
disgust, shut it down, and restart.  The lesson to take away is that  
Eclipse is what has the jars locked; this is strongly implicated by  
the fact that I personally more or less never use the workspace  
resolver.  I suspect that retrieving the artifacts rather than using  
them from cache would help to some degree, though I've not yet  
investigated this possibility.
