Re: [p2-dev] replacing default p2 uninstall action

["Meling, Matthias" <matthias.meling@xxxxxxxxxxx>]

Hi Johannes,

Instead of using a p2.inf file, can't you just edit the contents.xml that is created? This is of course a somewhat ugly solution... 

Otherwise you could have a look at org.eclipse.equinox.p2.publisher.actions.RootFilesAction.generateRootFileIUs(String, IPublisherResult). There the standard uninstall-instruction should be overwritten by your customized one.

( This is the "standard" instruction:

String unConfigurationData = "cleanupzip(source:@artifact, target:${installFolder});"; //$NON-NLS-1$

  touchpointData.put("uninstall", unConfigurationData); //$NON-NLS-1$

processTouchpointAdvice(cu, touchpointData, info, configSpec); )

Unfortunately I don't know how to debug this, as I always start the generation process from "Export...". Perhaps someone has a hint on how to do that?

Regards

Matthias

Hi,

We're currently trying to update the jre bundled with our rcp app using p2. I've documented my progress so far in the corresponding bug: 

https://bugs.eclipse.org/bugs/show_bug.cgi?id=300812#c29

My current problem is I am unable to override the root.win32.win32.x86.folder-instruction in my build.properties using instructions.uninstall=myUninstallAction in my p2.inf.


Any ideas?

Regards
Johannes
