We’ll talk about branches and how to use branches in the next video. They only merge the code into the main branch when they’re ready.īranches are slightly more advanced. ![]() Here, different people work on the code in different branches. If you encounter a conflict that is hundreds of lines long, it’ll be hard to resolve. This helps because it is easy to resolve a small conflict like the one we just resolved. Commits are free, so just make more commits. That means you make a commit for every little thing you do. The first way is to reduce the size of your commits. Preventing conflicts from happeningĬonflicts happen when two or more people work on the same file at the same time. What you need to do next is to push the changes up to the Git remote.Īnd this is how you resolve a Git conflict. If you look at the Git history, You can see that the remote master branch has a link back to the local master branch. This means our local branch is two commits ahead of the remote. When you commit the changes, you’ll see that the master branch in the sidebar says 2 up. If you look at the commit message area, you’ll see that Fork has filled in a commit message for you automatically. If the change is different, you will need to stage the files.Īfter staging, you need to commit the merge. In our case, the change is the one on our local, so we don’t see any files that need to be staged. When you head back to Fork, you’ll see that the changes are updated. Hello world! This is my third Github repo! Committing the merge What you’ll do is delete everything else that’s incorrect. In this case, let’s say “third” is the correct version. To fix the conflict, you choose the correct line of code. We need to choose between the “second Github repo” or the “third Github repo”. The code between > is the code from the remote repository (their code). If you open README.md now, you’ll see lines that say this: > snt2h1s3n4tnthd9au8d3324 The easiest way to resolve a conflict is to change the file on your computer. Git helps us do the merge automatically if it knows what is changed first, and what is changed later, and there are no ambiguities.īut, when there is a conflict, Git doesn’t know which version is correct - so you have to merge the code yourself. When you pull changes from the remote branch to the local branch, the change from the remote branch is merged into the local branch. In this case, it is the README.md file.įirst, let’s talk about why you need to merge. Here, you’ll see the files that contain conflicts. To see the conflict, you can go back to the changes section. What this means is you need to fix the conflict before you continue. In Fork, it says “Merging branch origin/master into master. This error message may be slightly different depending on the Git client you’re using. When you pull the changes, you’ll see an error message. We need to pull our changes onto our local branch to consolidate the changes. At the same time, our master branch has one commit ahead of the remote. This tells us there is one commit in the Git remote that is ahead of our master. If you look at the branch on the left, you can see that the master branch says one down one up. This happens because there are changes on the Git remote and on our local repository at the same time. Once the fetch is completed, you can see that origin/master is on a different fork compared to master. You can check for an update in your Git Client with the “Fetch” button. We’re going to commit this file and set the commit message to “Change first to third.” Hello world! This is my third Github repo! Instead of “second Github repository”, we’re going to say “third Github repository”. We’re also going make a commit message that says “Changed first to second” to see the effects in our Git History later.įor the second set of code, you can change the same README.md file on your local repository. ![]() ![]() Let’s say we change the text in README.md from “Hello world, this is my first Github repo” to “Hello world, this is my second Github repo”. In our case, we edit the files on GitHub to simulate a change. For the first set, we need someone to push code into the remote. To produce a Git conflict, we need two sets of code. You’ll learn how to resolve a Git conflict today.įirst, let’s produce a Git conflict so you see what happens. This happens because Git no idea whether your friend’s version is the updated version or your version is the updated version. When you pull their changes into your local repository, you’ll notice that there is a conflict. At the same time, you also made a change to the same line of code. Let’s say a friend of made a change to your repository and pushed the changes to the Git remote. Note: This the sixth video in the Git for beginners series.
