[tycho-user] Exporting a Target Definition file

[Aaron Digulla <digulla@xxxxxxxx>]

Hello,

The story so far. Since the mirror options in the p2 ant tasks either  
download too much (the whole site with all versions of all IUs, >> 1Gb  
for Indigo) or too little, I used a script to download features.

Basically the script installs Eclipse, runs the ant task to install  
the feature(s) I want and then deletes all the files which came from  
the install ZIP. Which leaves me with a set of files in  
features/plugins which work with the least amount of effort.

Then I was told that Eclipse has a Target Definition editor which  
could do the same for me.

I was able to create a Target Definition file (took me only 3 days  
because of various bugs in the editor; that's about the same amount of  
work my first approach took, so I'm not sure how much there is to be  
gained here... in fact with my own tool set, I know what every part  
does and how to fix it.)

When I click the "Export" button, Eclipse considers my puny request  
for half an hour and then creates a directory with features and  
plugins. This p2 repo is broken - Tycho won't find the SWT fragments  
in it, for example - but it's a start. Using the  
org.eclipse.equinox.p2.publisher.FeaturesAndBundlesPublisher, I can  
convert this into something that Tycho will like.

But I'd like something that I can pass on to a fellow developer  
without many explanations: I want to 100% automate the process.

Is there an ant task or a Tycho plugin to export a *.target file into  
a p2 repository?

Is there a better way to do this?

Regards,
