Re: [p2-dev] Specify required execution environment

[Andrew Niefer <aniefer@xxxxxxxxxx>]

I see import package statements in  org.eclipse.equinox.security_1.0.200.v20090520-1800.
 The metadata generator doesn't do an analysis on the classes themselves.

For the javax.security.auth.spi package,
you need an IU to represent the execution environment.  This is generally
done automatically for products,  by default there is a "a.jre.javase"
version="1.6.0" IU which provides the packages for that EE.  We
have code that generates these IUs for any execution environment, but we
don't currently have any command line tools or ant tasks to do it.  The
simplest way to get the IU would be to mirror it out of another repo that
already contains it, or to run a product build to get one generated.

I have created a feature including a few
equinox bundles for an eventual server container driven by equinox. I have
exported this feature and others into a p2 repository. That works fine.

I can see some requirements in the metadata for the org.eclipse.equinox.security
IU. Namely:

<requires size='18'>    
   <required namespace='java.package' name='javax.crypto'
range='0.0.0'/>        <required namespace='java.package'
name='javax.crypto.spec' range='0.0.0'/>        <required
namespace='java.package' name='javax.security.auth' range='0.0.0'/>
       <required namespace='java.package' name='javax.security.auth.callback'
range='0.0.0'/>        <required namespace='java.package'
name='javax.security.auth.login' range='0.0.0'/>      
 <required namespace='java.package' name='javax.security.auth.spi'
range='0.0.0'/>        <required namespace='java.package'
name='org.eclipse.core.internal.runtime' range='0.0.0'/>    
   <required namespace='java.package' name='org.eclipse.core.runtime'
range='0.0.0'/>        <required namespace='java.package'
name='org.eclipse.core.runtime.jobs' range='0.0.0'/>      
 <required namespace='java.package' name='org.eclipse.core.runtime.preferences'
range='0.0.0'/>        <required namespace='java.package'
name='org.eclipse.osgi.framework.log' range='[1.0.0,2.0.0)'/>  
     <required namespace='java.package' name='org.eclipse.osgi.service.datalocation'
range='[1.0.0,2.0.0)'/>        <required namespace='java.package'
name='org.eclipse.osgi.service.debug' range='[1.0.0,2.0.0)'/>  
     <required namespace='java.package' name='org.eclipse.osgi.service.environment'
range='[1.1.0,2.0.0)'/>        <required namespace='java.package'
name='org.eclipse.osgi.util' range='[1.1.0,2.0.0)'/>      
 <required namespace='java.package' name='org.osgi.framework' range='[1.4.0,2.0.0)'/>
       <required namespace='java.package' name='org.osgi.service.prefs'
range='[1.1.0,2.0.0)'/>        <required namespace='java.package'
name='org.osgi.util.tracker' range='[1.3.3,2.0.0)'/>      </requires>

This is the org.eclipse.equinox.security
bundle version 1.2.0.I20090522-1010.

It looks like the metadata generator got those requirements not from the
manifest, but by analyzing the classes in the bundle, because the bundle
manifest has no package imports, only required bundles. But that is not
my question :)

I am trying to install a feature with this bundle a few different ways
(installer, agent and director) and none work. They all complain that there
is no provider of the javax.security.auth.spi package. For example the
agent output is:

Cannot complete the install because one
or more required items could not be found.
  Software being installed: Equinox OSGi Core and Runtime Bundles
Feature 3.5.0.r001 (com.infor.container.equinox.core.feature.feature.group
3.5.0.r001)
  Missing requirement: Equinox Java Authentication and Authorization
Service (JAAS) 1.0.100.v20090520-1800 (org.eclipse.equinox.security 1.0.100.v20090520-1800)
requires 'package javax.security.auth.spi 0.0.0' but it could not be found
  Cannot satisfy dependency:
    From: Equinox OSGi Core and Runtime Bundles Feature 3.5.0.r001
(com.infor.container.equinox.core.feature.feature.group 3.5.0.r001)
    To: org.eclipse.core.net [1.2.0.I20090522-1010]
  Cannot satisfy dependency:
    From: Internet Connection Management 1.2.0.I20090522-1010
(org.eclipse.core.net 1.2.0.I20090522-1010)
    To: bundle org.eclipse.equinox.security [1.0.0,2.0.0)

We intend to run this with Java 1.6, and I expect the boot classloader
to provide those packages. How do I tell the installer, agent, and directory
that this will be the case?
