Automatically install features? [message #484884]

Quick question (having just lost my 30-min post to a buggy preview post button I don't feel like making this long)

I want to install the Eclipse Modelling Framework automatically (via the command line) on top of my existing Eclipse 3.5 CDT distribution from a local site archive (emf-xsd-Update-2.5.0.zip).

When I run

java -cp startup.jar org.eclipse.core.launcher.Main
    -application  org.eclipse.update.core.standaloneUpdate
    -command addSite
    -from emf-xsd-Update-2.5.0.zip

I get

Exception in thread "main" java.lang.NoClassDefFoundError: org/eclipse/core/launcher/Main

Help!

Ok, so I was being a bit of a noob and using the 3.2 documentation instead of the 3.5 documentation ( http://help.eclipse.org/galileo/topic/org.eclipse.platform.d oc.isv/reference/misc/update_standalone.html) and the command line stuff has changed from startup.jar to the plugins/equinox stuff.

So now it runs and I can add a local site from an extracted emf update site. However, I'm struggling to add the features - when I try to add them I get an error that the feature could not be found at the location.

So I did

java -jar plugins/org.eclipse.equinox.launcher_<version>.jar
    -application  org.eclipse.update.core.standaloneUpdate
    -command addSite
    -from my_extracted_emf_dir

And that worked and it said the site had been added.

However, I then tried to add a feature.

java -jar plugins/org.eclipse.equinox.launcher_<version>.jar
    -application  org.eclipse.update.core.standaloneUpdate
    -command install
    -featureId emf_feature_name
    -version 2.5.0_blah
    -from my_extracted_emf_dir

But that borked out, saying that there was no rasource type on the -from url. Fine, so I added file:/ to the front of the absolute directory path to the extracted site update. However, that now fails saying that it cannot find the feature.

Going back into eclipse and checking the update UI, the local site doesn't even show up, so I'm now worndering if that even worked.

Any help would be greatly appreciated - has anyone done this or is there a quicker way to install all the features out of a site .zip archive? I am going to need to do this for EMF, GEF and the Linuxtools packages, all of which are distributed as these site .zip files.

So I'm still being a noob and not reading the massive warning at the top of that help page that the method is deprecated and I should be using the p2 director instead: http://help.eclipse.org/galileo/topic/org.eclipse.platform.d oc.isv/guide/p2_director.html

Will give that a bash and might come back if I still have problems...

Ok, so I think I'm slowly getting there...

I have got the P2 director looking at a local site for fetaures, but I'm now running into a problem. If I point the remote site url at

file:/path/to/emf-site.zip

java -jar plugins/org.eclipse.equinox.launcher_<version>.jar
    -application org.eclipse.update.core.standaloneUpdate
    -command mirror
    -from file:/path/to/emf-site.zip
    -to .

Then it tries to open the file

/path/to/emf-site.zip/site.xml

So it doesn't seem to understand a zipped site. That's fine, but if I unzip the site manually and pass the p2 director:

file:/path/to/emf-site-extracted

Then it analyses the features ok, but when it comes to install them it bombs out with a file not found error. This seems to be caused by the plugins in the extracted site zip being .jar.pack.gz files, but the site.xml refers to the plugins as plain .jar files. Any ideas how to fix this?
