[sorry for non-highlighted links - angry forum engine prevents me from making them :/]

Hello, i am trying to automate downloading eclipse packages jars from eclipse repositories like download.eclipse.org/releases/indigo without needing to run eclipse IDE at all, but stuck here with no documentation and idea how to proceed.

With little effort and plenty of time i was able to wrap all eclipse <-> repo http traffic into my little transparent squid porxy; here is dialog when installing egit extention: paste.pocoo.org/show/546345/

It was helpful for get basic pattern of URL constructing; it is ${repoUrl}/${repoChildName}/aggregate/plugins/${packageName}_${packageVersion}.jar.pack.gz; but for some reason not all packages are available for such downloading (bot almost all, yes).

I am speaking about such basic packages like jface or swt, URLs constructed for them in that manner simply not working - server returns 404 on them.

It is also not possible to delete them and look at the dialog of eclipse downloading them because they are required for eclipse very functioning.

Any hints how to fetch such packages and fetch them for correct architecture (in case of SWT)?

Thank you.

P2 has several headless ant tasks. Check out the following page:

There are some shell script wrappers at

We use the b3 aggregator to perform tasks like that.
You create a model of what you want from where using an editor, and then
run that from the command line.

The model of p2 that is included is also very useful for writing
utilities that manipulate p2 data, or operates on repositories.

It may be total overkill depending on what you want to do.

Thank you a lot! This p2-scripts set is exactly what i was missing for understanding basics of p2 repos structure. Though there is still a lot of dark places for me, but ultimately i see now the way of illuminating them.
