using jgit with railo

[Michael Sprague]

I've been trying to get some Git integration set up via CFML on Railo and am wondering if anyone here has worked with jGit before.. I have tried adding jGit to the classpath and loading it via the javaloader cfc and I can't seem to get anything past that working. I found the documentation here ( http://wiki.eclipse.org/JGit/User_Guide#Repository ) but it doesn't help me much with getting started. 

Right now I just want to pass in the local directory of the repository and do a git status which seems like it should be simple enough but I think my lack of Java experience is getting in the way. Does anyone have any advice or experience setting this up? Thanks in advance.

I've tried using jGit before but got nowhere, so gave up and used a
shell script.

If all you need is "git status" you don't even need a script.

You can't do what I was initially thinking ("cd #Dir# && git status" -
works from command line but cfexecute complains that 'cd' isn't a
program), but what you can do is tell git to look at a different
directory like this:

<cfexecute
variable = "GitStatus"
name = "git --work-tree=#Dir# --git-dir=#Dir#/.git status"
timeout = 2
/>

(On Windows, if you don't have git on the path, you'll need
"C:\Program Files (x86)\Git\bin\git" there instead.)

I agree with peter,

I tried to use jGit but when I tried it you needed to understand all the internals of how git works to even do anything.

So I opted for the execute. Someday if jGit is actually usable I would like to use it since it would be nice to get information back from it without having to parse it.

If you do get jGit working let us know how :)

I had tried using cfexecute previously but didn't know how to pass the directory in. I just tested Peter's code and that did the trick. Thanks, Peter.

Long story short, I just want to write a commit hook for the main repository so when we push changes there it will update a testing server without having to ssh or remote in to do it. 

At some point I'd like to do some more complex work with it so hopefully jGit will become a bit more user friendly in future releases.

Thanks for the replies.

I've got two extensions for jGit-- one that uses the "deep down" API and
isn't very functional, and one that uses the CLI jar, which does
everything that the CLI can do, pretty much (forced checkouts were not
working last I checked, but I haven't updated it in a bit).

They should be in github before too long (in assembla somewhere right
now, I think).

I'd be interested in checking out both once they're available. If you don't mind, please reply here once they are.

Thanks,

I've been using the cfexecute method for git commands as well. I've
been doing it like this:

<cfexecute name="/bin/bash" arguments="-c 'cd -P #ExpandPath('/')#;
git rev-parse --short HEAD'" variable="server.codeversion"
timeout="1" />

This gets the latest short git log hash into a variable, which I then
tack onto my CSS link tags like this:

<link type="text/css" rel="stylesheet" href="/styles/global.css?
v=<cfoutput>#server.codeversion#</cfoutput>">

But I've been reading places that say that cfexecute has a lot of
overhead/cost so it should be run on every page request. I have this
inside a function that runs onApplicationStart or whenever I pass in a
specific url parameter - which I would run once after each deployment
to reinitialize certain global variables and functions.


I'd be interested in jgit too. I'll look into it and post back here if
I get anything working.

I'll holler when they're in their own project in github, but FWIW, using
the CLI jar is as easy as calling the main method with the arguments
you'd pass the command line executable.

It'll be bundled up into an extension though, so you won't have to
bother finding/installing jars, etc..

Cool, I may try playing around with the CLI jar this weekend then. Thanks, and looking forward to checking out the extensions.
