Eclipse - error executable jar file

When I use the eclipse function export - executable jar etc ...

I get a message when It's making the jar

JAR export finished with warning. See details ...

Details : Could not read JAR file '.classpath'. Reason : error in opening zip file.

I have no idea what this means and what I need to do to solve this ...

Anyone an idea?

When you are packaging your application with the Runnable Jar File, this message is usually associated with some kind of permission issue on a %TEMP% directory.

Check also if the option to generate a script display the same behavior when executed.
