java.io.IOException: File that was copied to backup could not be deleted: ... eclipse.exe [message #1585260]

Hi,

I'm building a self updating RCP product using the approach described here:
https://mahichir.wordpress.com/2012/08/07/eclipse-rcp-and-p2-headless-update-on-startup/
The product is then packaged as native executable installer (using Advanced Installer tool) and distributed. It usually gets installed in the program files folder. At some point I package an update (p2 repository using the Product Export wizard) and upload it to an update site.
The product gets the update, but the update operation fails with a message:

!MESSAGE Backup of file C:\Program Files\MyCompany\MyProduct\eclipse.exe failed.
!STACK 0
java.io.IOException: File that was copied to backup could not be deleted: C:\Program Files\MyCompany\MyProduct\eclipse.exe
	at org.eclipse.equinox.internal.p2.touchpoint.natives.BackupStore.moveToBackup(BackupStore.java:282)
	at org.eclipse.equinox.internal.p2.touchpoint.natives.BackupStore.backup(BackupStore.java:248)
        .............

The complete log file is attached.

I'm using Eclipse Luna 4.4.1 both as IDE and a target platform.
I'm wondering why P2 tries to replace the eclipse.exe file in the existing application? Can I tell somehow the repository to not include this binary artifact (eclipse.exe), so that the update goes smoothly - probably during the export?
At this moment I manually patch the generated content.xml (in the content.jar) in the p2 repository by removing the occurences of the eclipse.exe native artifact.

Any help would be appreciated.

Best Regards,
Dinko

I'm seeing a similar problem.

I'm using Eclipse Luna 4.4.2 as my target platform, and the class BackupStore is in version 1.1.100.v20140523-0116 of the org.eclipse.equinox.p2.touchpoint.natives bundle.

When I try to update my RCP application, I get this stack trace...

Similar error, different file than yours.

I hope someone sees this and offers us some pointers on how to get around this issue.

try to start eclipse update via luncher.jar instead of eclipse.exe for update process. There is a bug for windows. https://bugs.eclipse.org/bugs/show_bug.cgi?id=427148

Try starting eclipse update via "plugins/org.eclipse.equinox.launcher_1.3.0.v20130327-1440.jar"
