Using ordinary git checkout
the command works exactly how I would expect it to. Here are the use cases I am trying to allow for with the same piece of code:
1) git checkout branchname
where branchname
does not exist locally but does on remote
2) git checkout branchname
where branchname
already exists locally
3) git checkout commitid
For context, the repository has previously been cloned as follows:
repo = Git.cloneRepository()
.setCloneSubmodules(true)
.setURI(repoUrl)
.setDirectory(createTempDir())
.setCloneAllBranches(true)
.call();
The standard JGit checkout command does not automatically create branches locally. The following piece of code works for scenarios 2 and 3:
repo.checkout()
.setName(branchOrCommitId)
.call();
With the amendment to create a new branch it only works with scenario 1:
repo.checkout()
.setCreateBranch(true)
.setName(branchOrCommitId)
.call();
Is there a neat solution to this issue I can use, considering the standard Git CLI already provides the automatic functionality within the command I am looking for?
Find the remote branch in remotes -> origin , then double-click that branch to get it selected locally.
There is no actual command called “git checkout remote branch.” It's just a way of referring to the action of checking out a remote branch. Git is a way for software developers to track different modifications of their code. It keeps all the various versions in a unique database.
First, make sure that the target branch exists by running the “git branch” command. Now that you made sure that your branch exists, you can switch from the master branch to the “feature” branch by executing the “git checkout” command. That's it!
What you want to do is create a branch if and only if a local one is NOT present. Here's what I came up with using streams where exampleRepo is the git repo object, checkout command is the CheckoutCommand, and branchName is the branch name.:
git.setCreateBranch(git.branchList()
.call()
.stream()
.map(Ref::getName)
.noneMatch("refs/heads/" + branchName);
