Reloading on Windows fails to delete tmp dir

[Adam Payne]

You might need to add a sleep between stopping jetty and redeploying. It looks like jetty can't delete and recreate the temp explode directory. I'd guess it's possibly because the stopping server still has a lock on it.

File watcher detected changes of the war file. Reloading webapp automatically as configured.

Yes, that's file lock. I managed to get rid on the error setting

    <Set name="persistTempDirectory">true</Set>

Thanks a lot akurdyukov!
For those (like me) not fluent in Jetty-lore: you have to create a file jetty-web.xml inside your WEB-INF dir, with the following contents:

<?xml version="1.0"  encoding="ISO-8859-1"?>
<!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN" "http://www.eclipse.org/jetty/configure.dtd">
<Configure class="org.eclipse.jetty.webapp.WebAppContext">
    <Set name="persistTempDirectory">true</Set>
</Configure>
