I want to get the last commit metadata (the youngest one by date) in a repository using JGit. I know that I can get the commit metadata using try (RevWalk walk = new RevWalk(repository)) { RevCommit commit = walk.parseCommit(repository.resolve(commitHash)); } But how to get the latest commit hash? Is there any other way to get the youngest by date RevCommit in a repository directly? Grzegorz Górkiewicz Compare by dates of last commits in all branches. ListMode.ALL can be changed to ListMode.REMOTE to compare only remote branches. Or... the fluent setter .setListMode(whatever) can be omitted to

Is there a way to programmatically download a single file from a remote git repository, in Java? I prefer a solution which uses as little bandwidth as possible, preferably only downloading that single file. I do not need to browse the repository, I already have the file's path. I prefer a solution which does not depend on other applications (e.g. an installation of another git client on the machine). A Java library which contains a git client implementation itself would be optimal. I was able to do something similar with Subversion using SVNKit and I've seen there is a pure java implementation

I am playing around with cloning a remote existing repo with jGit following the guide here: https://github.com/centic9/jgit-cookbook/blob/master/src/main/java/org/dstadler/jgit/porcelain/CloneRemoteRepository.java I'm using CFML for my example: Git = createObject( 'java', 'org.eclipse.jgit.api.Git' ); localPath = createObject( 'java', 'java.io.File' ).init( expandPath( 'temp' ) ); result = Git.cloneRepository() .setURI( 'https://github.com/github/testrepo.git' ) .setDirectory( localPath ) .call(); result.close(); The clone works great, but file locks are not released on "pack" files inside

How do I merge in JGit? Let's say I want to merge master with foo branch, how do I do this? To merge, you can use the MergeCommand (in package org.eclipse.jgit.api), after a CheckoutCommand . To provide you with an example, because indeed Jgit lacks examples: Git git = ... // you get it through a CloneCommand, InitCommand // or through the file system CheckoutCommand coCmd = git.checkout(); // Commands are part of the api module, which include git-like calls coCmd.setName("master"); coCmd.setCreateBranch(false); // probably not needed, just to make sure coCmd.call(); // switch to "master"

I am trying to use JGit to get the differences of a file from the last commit to the most recent uncommitted changes. How can I do this with JGit? (using the command line would be the output of git diff HEAD ) Following several discussions ( link1 , link2 ) I come with a piece of code that is able to find the files that are uncommited, but it I cannot get the difference of the files Repository db = new FileRepository("/path/to/git"); Git git = new Git(db); AbstractTreeIterator oldTreeParser = this.prepareTreeParser(db, Constants.HEAD); List<DiffEntry> diff = git.diff().setOldTree(oldTreeParser
