In case you are using the Tower Git client, you can simply right-click any commit and choose "Check Out " from the contextual menu: The Detached HEAD State However, you are now also in a state called "Detached HEAD". You will then have that revision's files in your working copy. To checkout a specific commit, you can use the git checkout command and provide the revision hash as a parameter: $ git checkout 757c47d4 Maybe you want to experiment with a specific, old revision and therefore need to have that revision's files in your working copy folder. There are very few reasons to checkout a commit (and not a branch). In case you are using the Tower Git client, you can double-click the branch you want or (in case you have lots and lots of branches) simply use the "Quick Action" dialog to enter the branch's name, not using the mouse at all: Checking Out Commits Any new commits you make from this point on (until you switch branches again) will be recorded in this branch's context. This branch will then be your current working branch, also referred to as "HEAD" in Git. With the git switch command (or, alternatively, the git checkout command), you can simply provide the name of the branch you want to checkout. Here's how to do this: $ git switch my-branch As said, most of the time you'll want to "checkout" branches, and not individual commits. This makes branches a very safe and convenient tool in Git. The user does not have to do this manually. This also means that, if a new commit is made in that context, the branch pointer is automatically moved to that newest commit. This means that, actually, branches don't point to a certain commit but really always to the latest commit on the corresponding branch. Branches are very practical because they are pointers to the latest commit in a certain context (it helps to think of branches simply as specific, separate contexts with names). The Spring environment will pickup the git.properties files.Īctuator will identify that the file exists and will expose it on the properties.Most of the time, you will want to checkout a branch (and not a specific revision). This was pretty seamless so let’s explain what happens behind the scenes.īy doing mvn clean compile the git.properties file get’s generated.īy running the application, the info endpoint will be enabled based on the properties include=health,infoĬurl We shall be presented with the git information Can be done by adding the setting on the properties or env variables. Then you need to enable the info endpoint. Import .SpringBootApplication ĬonfigurableApplicationContext context = n(Application.class, args) So let’s import our Spring boot dependenciesĪlso we shall update our main class in order to spin up our Spring Boot Application On Spring we have actuator endpoints that show various information like health or in our case info.Įventually we can inject this information to the info actuator endpoint. It’s much easier to have an endpoint that exposes this piece of information, than checking binaries. Obviously this will work, the file will be located at target/classes/git.properties, but we do want to make it easier to retrieve that information. We will start by a simple maven Project with a hello world application. You did not cut off your new version yet and multiple deployment are executed, having that information included helps. Imagine the case of multiple deployments in a shared staging environment using the same version. The git commit-id plugin is very useful to depict the state of the git repository when a binary has been created.
