Java monitor GitHub repository

I want to create a Java application that monitors a GitHub repository, pulls changes to the machine it is running on and triggers a method when something in the repo has changed.

while(true)
{
    if(new commits on the remote github repo)
    {
        pullChanges();
        doSomething();
    }
}

I am currently using JGit and regularly deleting the local repository to clone a new one and compare the combined file size to check if anything has changed. This is incredibly hacky and not reliable (if a commit just changes a letter, the file sizes would be the same)

I changed it to clone the repository when the java application starts, after that I created a seperate thread that pulls new commits from the repository every 30 seconds and checks if something has changed with the 'FetchResult' returned from the Java method.

These helped me:

Cloning a repo

Pulling commits

You can use GitHub Webhooks.

Webhooks allow you to build or set up integrations which subscribe to certain events on GitHub.com. When one of those events is triggered, we'll send a HTTP POST payload to the webhook's configured URL. Webhooks can be used to update an external issue tracker, trigger CI builds, update a backup mirror, or even deploy to your production server. You're only limited by your imagination.

Your method to get a diff between your local copy and the remote is too tricky to be reliable.

See this post: How to check for changes on remote (origin) Git repository?
