Extracting information of remote repository [message #1384896]

I'm trying to extract some information like name, size, last modified, etc. from remote repositories using JGit.
Let's take a random GitHub repository. There would be something like build, src, test etc. with some description and the last modified date.
How can I get these information with JGit?
I'm not sure if I have to clone, to build or to do something else with the repository.
I'm using JGit for Eclipse, do I also need EGit?

I've found some old tutorials, but they don't work with the newest version of JGit (for example the imports are incorrect).

Could anybody please provide me with a working code snippet?

For which objects are you trying to extract name, size, last modified etc ?
For most details about objects stored in git you need to clone the repository.

I don't understand how jgit should be able to provide any information about
the build of your project.

Let's take for example github.com/jquery/jquery. You can find there information like:

tjvantoll authored Friday at 10:13 PM
timmywil committed Monday at 10:43 PM

build	Release: ensure Sizzle is the latest tag	12 days ago
src	Wrap: Declare a dependency on the manipulation module	2 days ago
test	Ajax: Support usage without jQuery.event	2 days ago
[...]

I need information like these. Are there methods like getAuthor(), getLastCommit(), etc?
If not, is there another framework which can provide me with these information from Git?

on which exact page do you see this information, looking at
https://github.com/jquery/jquery
I can't see that

Yes, you need to clone the repo in order to get at the kind of information you want.

org.spearce was renamed to org.eclipse, that might solve some problems. That was almost five years ago, so those tutorials
are pretty old and there are much better APIs nowadays. You should try to stick with the org.eclipse.jgit.api package as
much as possible.

We don't have much tutorials on JGit, except what's been written by third parties, but there's a lot of code in the
form of unit tests, the pgm package and of course EGit.
