[news.eclipse.platform] Updating a feature from a local update site with

[Blazej Kroll <blazej.kroll@xxxxxxxxxx>]

Hello!
I am trying to update a feature from a local update site (I unzipped a 
previously downloaded site) using headless Update Manger (I am using 
Eclipse 3.2.2 and am not able to change that right now).

I installed a feature in headless mode from locally created update site 
with:

java -cp startup.jar org.eclipse.core.launcher.Main -application 
org.eclipse.update.core.standaloneUpdate -command install -from 
file:///c:/UPSITE/myfeature_7.0.1.D071219  -featureId 
com.myfeature.feature -version 7.0.1.D071219

Now, when I like to use the update command of headless update manager I 
run into error. I unzip the new version of the feature to the previously 
used local directory and run update (note that I do not have an Internet 
connection)

java -cp startup.jar org.eclipse.core.launcher.Main -application 
org.eclipse.update.core.standaloneUpdate -command update -featureId 
com.myfeature.feature -version 7.0.1.D080604

Then it results in the following error:

Connection failed.
Command failed.

Is such a scenario doable with update manager? Does it require an 
Internet connection for updating properly or is it a bug?

Would really appreciate your help,
