Eclipse Oomph: Checkout a Tag instead of a Branch? [message #1733717]

Is it possible to checkout a tag instead of a Branch with Oomph?

Context:
We would like to have an Oomph Steam that does the checkout of the release commit (where the maven version is fixed to a fix version instead of the SNAPSHOT version we have in our branches). For the moment this commit is only marked with a TAG and not with an explicit branch.

Thank you in advance.

Jeremie,

No, the code right now wants to create a local branch with the name in
the task.

For future reference, this is the stack trace:

Is there any particular reason why Oomph cannot create a local branch from a remote tag? Or is this just a bug?

It's simply designed to check out a branch for an existing remote branch.

private static void createBranch(SetupTaskContext context, Git git,
String checkoutBranch, String remoteName) throws Exception
{
context.log("Creating local branch " + checkoutBranch);

CreateBranchCommand command = git.branchCreate();
command.setUpstreamMode(SetupUpstreamMode.SET_UPSTREAM);
command.setName(checkoutBranch);
command.setStartPoint("refs/remotes/" + remoteName + "/" +
checkoutBranch);
command.call();

StoredConfig config = git.getRepository().getConfig();
config.setBoolean(ConfigConstants.CONFIG_BRANCH_SECTION,
checkoutBranch, ConfigConstants.CONFIG_KEY_REBASE, true);
config.save();
}

We'd have to write different logic to create a branch for a tag instead
of an exiting "checkoutBranch". So it's working as designed, hence not
a bug.

Of course it's possible in principle to create a local branch for an
existing remote tag, but we've not designed that. You could open a
Bugzilla enhancement request for that (or just create a remote branch
for the tag)...
