So, at the exact spot where a new release is cut, you bump-that is, increase-the version number and then add a tag to that point. People often use tags for marking software versions. In other words, we’ll no longer be in detached HEAD state after this command. If you mark a commit with the tag “good-spot,” then you can use “good-spot” to refer to that commit instead of, say, a854d19. git checkout -b foo or 'git switch -c foo' (1) git branch foo (2) git tag foo (3) creates a new branch foo, which refers to commit f, and then updates HEAD to refer to branch foo. Think of them as a friendlier name for a commit. Git tags are labels or marks you can add to a commit. Alternative way would be to somehow avoid default git pull by Jenkins (that is required for Jenkins file since its in SCM repo) an find tag remotely inside the. Let’s start by answering some fundamental questions so we’re all on the same page. I’ll be testing the commands I write on both Windows and Linux (Ubuntu), but I expect them to work on macOS as well. We don’t make any assumptions regarding your choice of operating systems. You should be familiar with some basic Git commands.You should have Git installed on your system.You should be comfortable working with the command line.There are just a few requirements to follow along with this post: We’ll cover some fundamentals about both the git diff command and tags, so don’t worry if you’re not familiar with these terms.īy the end of the post, you’ll understand what tags are, how to diff them, and how to interpret the output of the diff itself. In this post you’ll learn how to compare two tags in Git. This command is very powerful and flexible, and it covers a lot of ground, but today we’ll be narrowing the scope down to the “git diff tags” use case. name : Git checkout : repo : '' dest : /srv/checkout version : release-0.22 - name : Read-write git checkout from github : repo : :mylogin/hello.git dest : /home/mylogin/hello - name : Just ensuring the repo checkout exists : repo : '' dest : /srv/checkout update : no - name : Just get information about the repository whether or not it has already been cloned locally : repo : '' dest : /srv/checkout clone : no update : no - name : Checkout a github repo and use refspec to fetch all pull requests : repo : dest : /src/ansible-examples refspec : '+refs/pull/*:refs/heads/*' - name : Create git archive from repo : repo : dest : /src/ansible-examples archive : /tmp/ansible-examples.zip - name : Clone a repo with separate git directory : repo : dest : /src/ansible-examples separate_git_dir : /src/ansible-examples.git - name : Example clone of a single branch : repo : dest : /src/ansible-examples single_branch : yes version : master - name : Avoid hanging when http(s) password is missing : repo : dest : /src/from-private-repo environment : GIT_TERMINAL_PROMPT : 0 # reports "terminal prompts disabled" on missing password # or GIT_ASKPASS: /bin/true # for git before version 2.3.In Git, you can use the git diff command for comparisons.
