Re: [p2-dev] Re: [pde-dev] error running P2 metadata generation 
I'm guessing it's either:

* your -config property, which needs a file: prefix, or
* -publishartifacts and/or -publishartifactrepository, which I've never used before, or 
* the fact that you're missing -site and/or -updatesite, or
* the fact that you've got file:/f:/ instead of file:f:/, as in the examples here [1]. 

http://wiki.eclipse.org/Equinox_p2_Metadata_Generator
Of course Ian will probably say you should be using the Publisher, not the Generator... 

http://wiki.eclipse.org/Equinox/p2/Publisher
But as it appears you're using Eclipse 3.4, not 3.5, you're stuck w/ last year's model until you upgrade.

Why would it be giving me this strange error?

Can you try
p2.gathering = true
(instead of generate.metadata = true). This should use the publisher (the new tool for generating metadata).

    Some guesses:

    * ${buildDirectory} is not defined
    * ${buildDirectory} contains spaces
    * ${buildDirectory} contains the wrong slashes
* repo.name <http://repo.name> properties need to be wrapped with quotes 

    You could try running the generator by hand and pass in all the
    required parameters. Here's the syntax I used the last time I had to
    regen metadata for an update site:

    cd /tmp/jbtm2nupdate/3.1.0.M2; rm -fr artifacts.jar content.jar; \
    /home/nboldt/eclipse/eclipse/eclipse -vm /opt/jdk1.5.0/bin/java \

        here is my product.properties file p2 segment:

        p2.metadata.repo = file:${buildDirectory}/repo
        p2.artifact.repo = file:${buildDirectory}/repo

        Artifact Repo
        p2.flavor = tooling
        p2.publish.artifacts=true

        can anyone shed some light on why I'm getting the NPE?
