This fix would help a lot. Thanks

We keep hitting this too Would love to see this fix integrated. Thanks!

Fixed in 1.9.2

Thanks for pulling in the fix! I am wondering if the new version would be released soon, so we can update the plugin.

I'm still seeing this on Windows 7 in Jenkins 1.5.27 using the 1.9.2 version of the cobertura-plugin.

I am seeing this issue after upgrading to 1.9.2. It is on Linux though. The plugin does not appear to play nicely with deleting the workspace before the next build.

I'm going to try excluding that file as a work around.

This didn't work. #realTime

It made it past deleting the workspace but eventually tried deleting that file during the build. It appears that there is some sort of process that holds on to that file for a minute or two after the build is complete? Should this be a new bug?

I have the same problem on three build slaves (Windows Server 2008 R2) with some build jobs.
Currently i remove the lock on the coverage.xml with the tool "unlocker".
