Fail to upgrade Jenkins on windows

[Alessandro Ferrucci]

I'm running jenkins on windows locally and whenever I try to upgrade it via the UI, it errors out with this:

jenkins.war Failure - java.nio.file.FileSystemException: C:\stuff\jenkins\jenkins.war: The process cannot access the file because it is being used by another process. at java.base/sun.nio.fs.WindowsException.translateToIOException(WindowsException.java:92) at java.base/sun.nio.fs.WindowsException.rethrowAsIOException(WindowsException.java:103) at java.base/sun.nio.fs.WindowsException.rethrowAsIOException(WindowsException.java:108) at java.base/sun.nio.fs.WindowsFileCopy.copy(WindowsFileCopy.java:164) at java.base/sun.nio.fs.WindowsFileSystemProvider.copy(WindowsFileSystemProvider.java:283) at java.base/java.nio.file.Files.copy(Files.java:1295) at org.apache.commons.io.FileUtils.copyFile(FileUtils.java:850) at org.apache.commons.io.FileUtils.copyFile(FileUtils.java:756) at hudson.lifecycle.Lifecycle.rewriteHudsonWar(Lifecycle.java:167) at hudson.model.UpdateCenter$HudsonUpgradeJob.replace(UpdateCenter.java:2482) at hudson.model.UpdateCenter$UpdateCenterConfiguration.install(UpdateCenter.java:1340) at hudson.model.UpdateCenter$DownloadJob._run(UpdateCenter.java:1875) at hudson.model.UpdateCenter$DownloadJob.run(UpdateCenter.java:1846) at java.base/java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:515) at java.base/java.util.concurrent.FutureTask.run(FutureTask.java:264) at hudson.remoting.AtmostOneThreadExecutor$Worker.run(AtmostOneThreadExecutor.java:121) at java.base/java.lang.Thread.run(Thread.java:834) I'm running Jenkins via java -jar jenkins.war The error makes complete sense since of course I'm running Jenkins at the time that it tries to update the war file, however this begs the question, how do other people update Jenkins while it's running? Thank you

Sounds a bit like Jenkins-19994

Hi,

Have you added all plugins(Windows) to the Jenkins?

That's hat you get when you run servers on Windows. Unlike Linux, Windows can't overwrite executables while they run (in this case your jenkins.war). You need to shutdown Jenkins, rpelace the file, start Jenkins.

Bye...

Jenkins can upgrade itself when run as a service in windows 

It can not when launched manually, at the same time it should not offer to update itself either.

You can install the service most simply with the msi installer, but then if you install is a package you should upgrade via a package to

So possibly install on a throw away VM then copy files and register the service manually.  I think there may even be some docs on jenkins.io to say how to do this.

It never worked back when we were running Jenkins on Windows (Server 2008 R2, as service). Fortunately we switched our controller to Linux some years ago...

For me it does upgrade itself perfectly well (Server 2016, Zulu Java, currently jenkins 2.319.2 running as service).

 Only issue: I better manually restart the service after that because sometimes my builds start getting awfully slow.
