Hello,

I have a problem and I just don't know what to try anymore:

I've created an Eclipse RCP application (feature based product) and now I want to support updates through p2. So far, so good. The steps for this are outlined in various blogs and articles but they just don't work for me. I'll reproduce them here. Please take a look and tell me what I've done wrong:

1. Export product repository (export product through wizard, check "Generate metadata repository"). Directory "repository" appears in output directory.

2. Run director application in order to export the product again, this time with p2 enabled (whatever that means). I've tried different ways to achieve it, including the graphical installer. I'll reproduce it for the director application:

eclipse -nosplash -application org.eclipse.equinox.p2.director
-metadataRepository file:${HOME}/output/repository
-artifactRepository file:${HOME}/output/repository
-destination ${HOME}/director_out
-bundlepool ${HOME}/director_out
-installIU de.[...].ui.product
-profile MyProjectProfile
-profileProperties org.eclipse.update.install.features=true
-p2.os linux -p2.ws gtk -p2.arch x86_64
-roaming
-debug -consolelog
-vmargs -Declipse.p2.data.area=${HOME}/director_out/p2

First question: What does the -profile parameter mean? All I've found on this tells me that it is a free-form string. What purpose does this serve?

3. Now, in theory, there should be a p2 enabled application in the -destination directory. The application is there and I can execute it. However, when I click on "Help" -> "Install New Software...", I get the familiar "Cannot complete the request. This installation has has not been configured properly for Software Updates." message and on the error log I see
"!ENTRY org.eclipse.equinox.p2.ui.sdk 2 0 2010-12-15 10:00:32.835
!MESSAGE Could not locate the running profile instance. The eclipse.p2.data.area and eclipse.p2.profile properties may not be set correctly in this application's config.ini file."

Among the settings in configuration/config.ini I find:

eclipse.p2.profile=MyProjectProfile
eclipse.p2.data.area=@config.dir/../p2

which seems to be correct.

Is there anything else that can cause this message? Maybe a missing plugin?

I've already searched the web for *hours* and all I can find is "Run director application".

Thanks in advance for your help.
