Problem downloading plugin in eclipse helios 2

Question

I am having problem in downloading my plug-in in eclipse helios2. the update site is: http://fast-code.sourceforge.net/install.htm . It worked fine up to helios1.

This is the error I get :

An error occurred while collecting items to be installed session context was:(profile=epp.package.jee, phase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=, action=). Problems downloading artifact: org.eclipse.update.feature,fastcodefeature,1.0.0.201012110203. Downloaded stream not a valid archive. Check the server.

Edit : here is my site.XML:

<?xml version="1.0" encoding="UTF-8"?>
<site>
   <feature url="features/fastcodefeature_1.2.0.jar" id="fastcodefeature" version="1.2.0">
  <category name="FastCode"/>
   </feature>
   <category-def name="FastCode" label="FastCode">
   <description>
     Fast Code Eclipse Plugin
  </description>
   </category-def>
</site>

now where it is getting the featured version: org.eclipse.update.feature,fastcodefeature,1.0.0.201012110203?

Answer 1

See "Downloaded stream not a valid archive. Check the server." May be archive isn't valid?

Answer 2

The problem is that your fastcodefeature_1.2.0.jar file is not a valid feature jar. It does not contain a MANIFEST.MF file. I would recommend rebuilding your feature (and associated plugins). File -> Export -> Deployable features should do the trick.
